(credit: Space Warps, Canada-France-Hawaii Telescope Legacy Survey) Foreword FOREWORD We advanced four missions to reinforce the WPI activities: science, fusion, globalization and system reform. I lined up those prominent scientifc results in “Research Highlights”. “Tea-time” scheme is keeping its impor- tant role as the mutual interaction among mathematicians, physicists and astronomer. Established interna- tional research environment could be seen in the large numbers of application for the post-doctorial posi- tions, the number of nearly 800 visitors with a half of them coming from abroad, organized 17 highly reputed international workshops and so on. The institute activated system reform in the University, result- ing honored UTokyo President’s Award for business transformation. We proposed an ambitious plan to include statistics in our research, joining a new international graduate program such as the Global Science Graduate Course (GSGC), created a new program to bring graduate students from Oxford University, push for new projects such as LiteBIRD, and make sure that the institute will be sustainable. We are looking into an even brighter future! Hitoshi Murayama Director t is my great pleasure to present the Kavli IPMU annual report for fscal year 2015. The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) was founded on October I 1, 2007. We proposed to address fve basic questions about the Universe, how it began, what it is made of, what its fate is, what its fundamental laws are, and why we exist in it. We do so by combining mathemat- ics, physics, and astronomy, employing accelerator-based experiments, underground experiments, and observations at telescopes. This Institute literally started from scratch, but now has grown to a size of about 150 people on site including graduate students and support staf. In 2015, we were extremely happy that the 2015 Nobel Prize in Physics was awarded to the Kavli IPMU Principal Investigator, Takaaki Kajita, director of the University of Tokyo Institute for Cosmic Ray Research. His historic discovery of neutrino oscillation provides us the key clue to the long-standing problem that we tackle “why do we exist in the Universe?” A tiny amount of neutrino mass could have tilted the balance between matter and anti-matter and prevented a complete annihilation of these two and hence us, which is a well-known theory proposed by M. Fukugita and T. Yanagida at the Kavli IPMU. The discovery motivates our leading neutrino experiments including T2K and KamLAND-ZEN. 2 Kavli IPMU Annual Report 2015 Kavli IPMU Annual Report 2015 3 Introduction STATISTICS Introduction Total Number of Staff 297 300 1 300 500 480 STAFF PUBLICATIONS 285 273 449 450 250 247 230 400 347 350 202 350 200 300 158 255 259 252 150 236 245 250 236 209 202 165 194 200 100 80 125 150 115 100 50 63 21 27 25 28 27 30 32 31 50 18 10 22 9 0 3 7 11 10 11 10 10 10 10 10 0 Oct. 2007 Mar. 2008 Mar. 2009 Mar. 2010 Mar. 2011 Mar. 2012 Mar. 2013 Mar. 2014 Mar. 2015 Mar. 2016 FY 2007 FY 2008 FY 2009 FY 2010 FY 2011 FY 2012 FY 2013 FY 2014 FY 2015 Researchers 18 63 125 165 194 209 236 245 255 259 Research Support Stafs 0 10 22 27 25 28 27 30 32 31 Administrative staf 3 7 11 10 11 10 10 10 10 10 Total 21 80 158 202 230 247 273 285 297 300 (1,000,000 JPY) Percentage of Overseas 3,910 RESEARCHERS 300 TOTAL 3,425 41% 35% 3500 3,372 40% 3,262 250 44% EXPENDITURE 38% 3000 2,844 2,844 2,707 1301 1024 1842 200 52% 98 105 90 1225 56% 105 2500 2,362 79 846 150 1410 100 2000 453 397 58% 1524 911 538 489 92 425 93 91 90 100 60 1500 1,366 92 96 117 231 444 653 574 27% 147 150 169 48 88 80 486 486 130 131 Personal 112 17 94 1000 404 234 50 Project Activities 896 28% 65 73 388 18 46 Travel Expenses 25 3 500 906 987 1027 1101 1023 1006 0 25 825 Oct. 2007 Mar. 2008 Mar. 2009 Mar. 2010 Mar. 2011 Mar. 2012 Mar. 2013 Mar. 2014 Mar. 2015 Mar. 2016 Equipment 288 635 Other Research Project 0 132 Overseas 5 17 60 92 100 79 105 98 105 90 FY 2007 FY 2008 FY 2009 FY 2010 FY 2011 FY 2012 FY 2013 FY 2014 FY 2015 Domestic 13 46 65 73 94 130 131 147 150 169 % of Overseas 28% 28% 48% 56% 52% 38% 44% 40% 41% 35% % of Female 0% 2% 5% 6% 5% 2% 5% 5% 6% 4% Visitors RESEARCH 1800 300 BREAKDOWN OF 1689 1600 2491449 246 ACTIVITIES 232 250 FY 2015 TOTAL 1400 549 222 196 1200 186 1201

    New directions in strong lensing Masamune Oguri RESCEU/Physics/Kavli IPMU University of Tokyo 2019/8/23 CosmoCruise@Sea Reference − arXiv:1907.06830 Strong gravitational lensing of explosive transients Masamune Oguri1,2,3 1Research Center for the Early Universe, University of Tokyo, Tokyo 113-0033, Japan 2Department of Physics, University of Tokyo, Tokyo 113-0033, Japan 3Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI), University of Tokyo, Chiba 277-8582, Japan E-mail: [email protected] Abstract. Recent rapid progress in time domain surveys makes it possible to detect various types of explosive transients in the Universe in large numbers, some of which will be gravitationally lensed into multiple images. Although alargenumberofstronglylenseddistantgalaxiesandquasarshavealready been discovered, strong lensing of explosive transients opens up new applications, including improved measurements of cosmological parameters, powerful probes of small scale structure of the Universe, and new observational tests of dark matter scenarios, thanks to their rapidly evolving light curves as well as their compact sizes. In particular, the compactness of these transient events indicates that the wave optics e↵ect plays an important role in some cases, which can lead to totally new applications of these lensing events. Recently we have witnessed first discoveries of strongly lensed supernovae, and strong lensing events of other types of explosive transients such as gamma-ray bursts, fast radio bursts, and gravitational waves from compact binary mergers are expected to be observed soon. In this review article, we summarize the current state of research on strong gravitational lensing of explosive transients and discuss future prospects.

  • Inflation, Large Branes, and the Shape of Space
    Inflation, Large Branes, and the Shape of Space Brett McInnes National University of Singapore email: [email protected] ABSTRACT Linde has recently argued that compact flat or negatively curved spatial sections should, in many circumstances, be considered typical in Inflationary cosmologies. We suggest that the “large brane instability” of Seiberg and Witten eliminates the negative candidates in the context of string theory. That leaves the flat, compact, three-dimensional manifolds — Conway’s platycosms. We show that deep theorems of Schoen, Yau, Gromov and Lawson imply that, even in this case, Seiberg-Witten instability can be avoided only with difficulty. Using a specific cosmological model of the Maldacena-Maoz type, we explain how to do this, and we also show how the list of platycosmic candidates can be reduced to three. This leads to an extension of the basic idea: the conformal compactification of the entire Euclidean spacetime also has the topology of a flat, compact, four-dimensional space. arXiv:hep-th/0410115v2 19 Oct 2004 1. Nearly Flat or Really Flat? Linde has recently argued [1] that, at least in some circumstances, we should regard cosmological models with flat or negatively curved compact spatial sections as the norm from an Inflationary point of view. Here we wish to argue that cosmic holography, in the novel form proposed by Maldacena and Maoz [2], gives a deep new interpretation of this idea, and also sharpens it very considerably to exclude the negative case. This focuses our attention on cosmological models with flat, compact spatial sections. Current observations [3] show that the spatial sections of our Universe [as defined by observers for whom local isotropy obtains] are fairly close to being flat: the total density parameter Ω satisfies Ω = 1.02 0.02 at 95% confidence level, if we allow the imposition ± of a reasonable prior [4] on the Hubble parameter.

Schwarz,3 Nathan Seiberg,1 and Edward Witten4 1Department of Physics, Rutgers University, Piscataway, NJ 08855-0849 2Institute for Theoretical Physics, University of California, Santa Barbara, CA 93106-4030 3California Institute of Technology, Pasadena, CA 91125 4Institute for Advanced Study, Princeton, NJ 08540 Abstract We consider various aspects of compactifications of the Type I/heterotic Spin(32)/Z2 theory on K3. One family of such compactifications in- cludes the standard embedding of the spin connection in the gauge group, and is on the same moduli space as the compactification of arXiv:hep-th/9605184v1 25 May 1996 the heterotic E8 × E8 theory on K3 with instanton numbers (8,16). Another class, which includes an orbifold of the Type I theory re- cently constructed by Gimon and Polchinski and whose field theory limit involves some topological novelties, is on the moduli space of the heterotic E8 × E8 theory on K3 with instanton numbers (12,12). These connections between Spin(32)/Z2 and E8 × E8 models can be demonstrated by T duality, and permit a better understanding of non- perturbative gauge fields in the (12,12) model. In the transformation between Spin(32)/Z2 and E8 × E8 models, the strong/weak coupling duality of the (12,12) E8 × E8 model is mapped to T duality in the Type I theory. The gauge and gravitational anomalies in the Type I theory are canceled by an extension of the Green-Schwarz mechanism.

  • 8.962 General Relativity, Spring 2017 Massachusetts Institute of Technology Department of Physics
    8.962 General Relativity, Spring 2017 Massachusetts Institute of Technology Department of Physics Lectures by: Alan Guth Notes by: Andrew P. Turner May 26, 2017 1 Lecture 1 (Feb. 8, 2017) 1.1 Why general relativity? Why should we be interested in general relativity? (a) General relativity is the uniquely greatest triumph of analytic reasoning in all of science. Simultaneity is not well-defined in special relativity, and so Newton's laws of gravity become Ill-defined. Using only special relativity and the fact that Newton's theory of gravity works terrestrially, Einstein was able to produce what we now know as general relativity. (b) Understanding gravity has now become an important part of most considerations in funda- mental physics. Historically, it was easy to leave gravity out phenomenologically, because it is a factor of 1038 weaker than the other forces. If one tries to build a quantum field theory from general relativity, it fails to be renormalizable, unlike the quantum field theories for the other fundamental forces. Nowadays, gravity has become an integral part of attempts to extend the standard model. Gravity is also important in the field of cosmology, which became more prominent after the discovery of the cosmic microwave background, progress on calculations of big bang nucleosynthesis, and the introduction of inflationary cosmology. 1.2 Review of Special Relativity The basic assumption of special relativity is as follows: All laws of physics, including the statement that light travels at speed c, hold in any inertial coordinate system. Fur- thermore, any coordinate system that is moving at fixed velocity with respect to an inertial coordinate system is also inertial.

  • Lessons from the First Multiply Imaged Supernova: a Revised Light-Traces
    Draft version August 26, 2020 Typeset using LATEX twocolumn style in AASTeX63 Lessons from the first multiply imaged supernova: A revised Light-Traces-Mass strong lensing model for the galaxy cluster MACS J1149.5+2223 Adi Zitrin1 1Physics Department, Ben-Gurion University of the Negev, P.O. Box 653, Be'er-Sheva 84105, Israel (Received; Revised; Accepted) Submitted to ApJ ABSTRACT Our light-traces-mass (LTM) strong-lensing model for MACS J1149.5+2223 has played several key roles over the last decade: it aided the identification of multiple images in this cluster and the study of MACS1149-JD1 at redshift z ' 9, it was used to estimate the properties of the first multiply imaged supernova, Refsdal, in its discovery paper, and of the first caustic crossing event by a cluster, Lensed Star 1. Supernova Refsdal supplied an invaluable opportunity to conduct a blind test of the ability of common lens-modeling techniques to accurately describe the properties of SN Refsdal's images and predict the reappearance of one of its counter images that was due about a year post-discovery of the original Einstein cross. Thanks to this practice, in which our submitted model yielded some outlying results, we located a numerical artifact in the time delay (TD) calculation part of the code, which was now fixed. This artifact did not influence the reproduction of multiple images (i.e., the deflection fields { which are those constrained directly from the observations) or the derived mass model, and so it remained unnoticed prior to supernova Refsdal, emphasizing the importance of blind tests in astronomy.

It is an autonomous institute fully funded by the Department of Atomic Energy, Government of India. Till October 10, 2000 the Institute was known as Mehta Research Institute of Mathematics and Mathematical Physics (MRI) after which it was renamed as Harish-Chandra Research Institute (HRI) after the internationally acclaimed mathematician, late Prof Harish-Chandra. The Institute started with efforts of Dr. B. N. Prasad, a mathematician at the University of Allahabad with initial support from the B. S. Mehta Trust, Kolkata. Dr. Prasad was succeeded in January 1966 by Dr. S. R. Sinha, also of Allahabad University. He was followed by Prof. P. L. Bhatnagar as the first formal Director. After an interim period in January 1983, Prof. S. S. Shrikhande joined as the next Director of the Institute. During his tenure the dialogue with the Department of Atomic Energy (DAE) entered into decisive stage and a review committee was constituted by the DAE to examine the Institutes fu- ture. In 1985 N. D. Tiwari, the then Chief Minister of Uttar Pradesh, agreed to provide sufficient land for the Institute and the DAE promised financial sup- port for meeting both the recurring and non-recurring expenditure.

It achieves this status in physics because it provides unification for contradictory laws of physics, namely quantum mechanics and general relativity. While based on advanced theoretical mathematics, its public discourse is growing in prevalence and its rhetorical power is leading to a scientific revolution, even among the public.
