THE COSMIC COCKTAIL Three Parts Dark Matter
release For immediate release Contact: Andrew DeSio Publication Date: June 11, 2014 (609) 258-5165 [email protected] Weaving a tale of scientific discovery, adventures in cosmology, and the hunt for dark matter, Dr. Katherine Freese explores just what exactly the universe is made out of in THE COSMIC COCKTAIL Three Parts Dark Matter “Freese tells her trailblazing and very personal story of how the worlds of particle physics and astronomy have come together to unveil the mysterious ingredients of the cosmic cocktail that we call our universe.” Brian Schmidt, 2011 Nobel Laureate in Physics, Australian National University What is dark matter? Where is it? Where did it come from? How do scientists study the stuff when they can’t see it? According to current research, our universe consists of only 5% ordinary matter (planets, comets, galaxies) while the rest is made of dark matter (26%) and dark energy (69%). Scientists and researchers are hard at work trying to detect these mysterious phenomena. And there are none further ahead in the pursuit than Dr. Katherine Freese, one of today’s foremost pioneers in the study of dark matter. In her splendidly written new book THE COSMIC COCKTAIL: Three Parts Dark Matter (Publication Date: June 11, 2014; $29.95), Dr. Freese tells the inside story of the epic quest to solve one of the most compelling enigmas of modern science—what is the universe made of? Blending cutting-edge science with her own behind-the-scenes insights as a leading researcher in the field, acclaimed theoretical physicist Katherine Freese recounts the hunt for dark matter, from the predictions and discoveries of visionary scientists like Fritz Zwicky— the Swiss astronomer who coined the term "dark matter" in 1933—to the deluge of data today from underground laboratories, satellites in space, and the Large Hadron Collider. -
Catherine Cesarsky, French Astrophysicist Astrophysics Is An
PROFILE - Catherine Cesarsky, French astrophysicist Astrophysics is an interdisciplinary branch of astronomy which mainly concerns the physics and study of the properties of objects in the universe (e.g. stars, planets, galaxies, interstellar medium), such as their luminosity, density, temperature and chemical composition, their formation and evolution. This field of research is a pillar of Franco-Swedish cooperation since astronomy and astrophysics is the second most important area of joint publications (after physics) between France and Sweden with more than 2,700 publications over the period 2010-2020. Over the years, French and Swedish astronomers have found reasons to cooperate in numerous programmes on the ground and in space, both on stars and their composition and on the interstellar medium, nebulae and galaxies. We had the pleasure of meeting a leading figure in this field and a foreign member of the Royal Swedish Academy of Sciences since 2005, Catherine Cesarsky. Read our interview below. You have a doctorate in astronomy from Harvard University, you did a post-doctorate at the California Institute of Technology, one of the largest research centres in astronomy, before returning to France and becoming a researcher in 1974 in the Astrophysics Department of the CEA in Saclay. Today you are President of the international project office for the construction of the world's largest radio telescope, SKA ("Square Kilometer Array"). What led you to take an interest in galaxies and more particularly in the origin and propagation of cosmic rays? These things often happen by chance. I was looking for a thesis supervisor when I was a student at Harvard University and I was lucky enough to meet an astrophysicist and plasma physicist from Princeton at a congress who offered me a summer job on cosmic rays. -

We study the compatibility of the observed DAMA modulation signal with in- elastic scattering of dark matter (DM) off of the 0:1% Thallium (Tl) dopant in DAMA. In this work we test whether there exist regions of parameter space where the Tl interpretation gives a good fit to the most recent data from DAMA, and whether these regions are compati- ble with the latest constraints from other direct detection experiments. Previously, Chang et al. in 2010 [1], had proposed the Tl interpretation of the DAMA data, and more recently (in arXiv:2102.08367v2 [hep-ph] 17 Mar 2021 2019) the DAMA/LIBRA collaboration [2] found regions in parameter space of Tl inelastic scattering that differ by more than 10σ from a no modulation hypothesis. -
Arxiv:2010.00015V3 [Hep-Ph] 26 Apr 2021 Galactic Halo Can Scatter with Exoplanets, Lose Energy, and Gles Are the Same Set of Planets, Without DM Heating
MIT-CTP/5230 SLAC-PUB-17556 Exoplanets as Sub-GeV Dark Matter Detectors Rebecca K. Leane1, 2, ∗ and Juri Smirnov3, 4, y 1Center for Theoretical Physics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA 2SLAC National Accelerator Laboratory, Stanford University, Stanford, CA 94039, USA 3Center for Cosmology and AstroParticle Physics (CCAPP), The Ohio State University, Columbus, OH 43210, USA 4Department of Physics, The Ohio State University, Columbus, OH 43210, USA (Dated: April 27, 2021) We present exoplanets as new targets to discover Dark Matter (DM). Throughout the Milky Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat flow within exoplanets. We estimate upcoming infrared telescope sensitivity to this scenario, finding actionable discovery or exclusion searches. We find that DM with masses above about an MeV can be probed with exoplanets, with DM-proton and DM-electron scattering cross sections down to about 10−37cm2, stronger than existing limits by up to six orders of magnitude. Supporting evidence of a DM origin can be identified through DM-induced exoplanet heating correlated with Galactic position, and hence DM density. This provides new motivation to measure the temperature of the billions of brown dwarfs, rogue planets, and gas giants peppered throughout our Galaxy. Introduction{Are we alone in the Universe? This ques- Exoplanet Temperatures tion has driven wide-reaching interest in discovering a 104 planet like our own. Regardless of whether or not we ever find alien life, the scientific advances from finding DM Heating and understanding other planets will be enormous. From a particle physics perspective, new celestial bodies pro- vide a vast playground to discover new physics. -

Kea, NASA/GSFC She lit up a room with her wonderful smile; she made everyone in her presence feel that they were important. On October 5, 2008 one of our rising stars in astronomy had fallen. Dr. Beth Brown was an Astrophysicist in the Science and Exploration Directorate at NASA’s Goddard Space Flight Center. Beth was always fascinated by space: she grew up watching Star Trek and Star Wars, which motivated her to become an astronaut. However, her eyesight prevented her from being eligible for astronaut training, which led to her pursuing the stars through astronomy. Beth pursued her study of the stars more seriously at Howard University where she majored in physics and astronomy. Upon learning that her nearsightedness would limit her chances of becoming an astronaut, Beth’s love for astronomy continued to grow and she graduated summa cum laude from Howard University. Beth continued her education at the University of Michigan in Ann Arbor. There she received a Master’s Degree in Astronomy in 1994 on elliptical galaxies and she obtained her Ph.D. -

FERMILAB-PUB-16-157-A A History of Dark Matter Gianfranco Bertone1 and Dan Hooper2;3 1GRAPPA, University of Amsterdam, Netherlands 2Center for Particle Astrophysics, Fermi National Accelerator Laboratory, USA and 3Department of Astronomy and Astrophysics, The University of Chicago, USA (Dated: May 26, 2016) Although dark matter is a central element of modern cosmology, the history of how it became accepted as part of the dominant paradigm is often ignored or con- densed into a brief anecdotical account focused around the work of a few pioneering scientists. The aim of this review is to provide the reader with a broader historical perspective on the observational discoveries and the theoretical arguments that led the scientific community to adopt dark matter as an essential part of the standard cosmological model. arXiv:1605.04909v2 [astro-ph.CO] 24 May 2016 2 CONTENTS I.
