2019 Astrophysics Senior Review Senior Review Subcommittee Report
2019 Astrophysics Senior Review Senior Review Subcommittee Report 2019 Astrophysics Senior Review - Senior Review Subcommittee Report June 4-5, 2019 SUBCOMMITTEE MEMBERS Dr. Alison Coil, University of California San Diego Dr. Megan Donahue, Michigan State University Dr. Jonathan Fortney, University of California Santa Cruz Ms. Maura Fujieh, NASA Ames Research Center Dr. Roberta Humphreys, University of Minnesota Dr. Mark McConnell, University of New Hampshire / Southwest Research Institute Dr. John O’Meara, Keck Observatory Dr. Rebecca Oppenheimer, American Museum of Natural History Dr. Alexandra Pope, University of Massachusetts Amherst Dr. Wilton Sanders, NASA/University of Wisconsin-Madison, retired Dr. David Weinberg, The Ohio State University - Chair 1 EXECUTIVE SUMMARY The eight missions evaluated by the 2019 Astrophysics Senior Review constitute a portfolio of extraordinary scientific power, on topics that range from the atmospheres of planets around nearby stars to the nature of the dark energy that drives the accelerating expansion of the cosmos. The missions themselves range from the venerable Great Observatories Hubble and Chandra to the newest Explorer missions NICER and TESS. All of these missions are operating at a high level technically and scientifically, and all have sought ways to make their operations cost-efficient and their data valuable to a broad community. The complementary nature of these missions makes the overall capability of the portfolio more than the sum of its parts, and many of the most exciting developments in contemporary astrophysics draw on observations from several of these observatories simultaneously. The Senior Review Subcommittee recommends that NASA continue to operate and support all eight of these missions. -
A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes
A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes WUJUN MI Doctoral Thesis Stockholm, Sweden 2019 KTH Fysik TRITA-SCI-FOU 2019:41 SE-106 91 Stockholm ISBN 978-91-7873-286-9 SWEDEN Akademisk avhandling som med tillstånd av Kungl Tekniska högskolan framlägges till offentlig granskning för avläggande av teknologie doktorsexamen i fysik fredagen den 27 september 2019 klockan 10.00 i E3, Osquars backe 14, Kungliga Tekniska Högskolan, Stockholm. © Wujun Mi, September 2019 Tryck: Universitetsservice US AB iii Abstract Over the past half century, the focusing X-ray telescope has played a very prominent role in X-ray astronomy at the frontier of fundamental physics. The finer angular resolution and increased effective area have enabled more and more exciting discoveries and detailed studies of the high-energy universe, including the cosmic X-ray background (CXB) radiation, black holes in active galactic nuclei (AGN), galaxy clusters, supernova remnants, and so on. At present, nearly all the state-of-the-art focusing X-ray telescopes are based on Wolter-I optics or its variations, for which the throughput is severely restricted by the mirror’s surface roughness, figure error, alignment error, and so on. Within the course of this work, we have developed a novel point-focusing refractive lens, the stacked prism lens (SPL), which is built by stacking disks embedded with various number of prismatic rings. As a Fresnel-like X-ray lens, it could provide a significantly higher efficiency and larger effective aper- ture than the conventional compound refractive lenses (CRLs). The aim of this thesis is to demonstrate the feasibility of the stacked prism lens and investigate the application to a next-generation hard X-ray telescope. -

The black holes are spinning in a non-aligned fashion, which means they have different orientations relative to the overall orbital motion of the pair. LIGO found a hint of this phenomenon in at least one black hole of the GW170104 system.

TRUMPER MPI fur Extraterrestrische Physik, D-8O46 Garching-bei-Miinchen The ROSAT launch on June 1, 1990 happened to be after the IAU Colloquium No. 123 before the deadline for submitting manuscripts. I therefore take the liberty to deviate grossly from the manuscript of my talk and give a short up to date mission summary. A more complete description of the mission can be found in References 1 and 2. The launch of the Delta II rocket was perfect and the orbital parameters reached are very close to nominal: height 580 km, inclination 53°. The predicted satellite's lifetime in this orbital is at least 10 years. The switch-on of the spacecraft and instrument subsystems could be completed without any losses. All systems are in good health. ROSAT carries two instruments: — a large Wolter telescope covering the energy range 0.1-2.4 keV with two position sensitive proportional counters (PSPC) and one high resolution imager (HRI) and — Wolter-Schwarzschild-telescope with two channel plate detectors covering the adjacent XUV-range. The novel features of the X-ray telescope are: — large collecting power — good spectral resolution of the PSPC's: AE/E ~ 0.4 at 1 keV; four colours — low background of the PSPC's: 3 x 10-5 cts/arcmin2 sec — high angular resolution with the HRI: < 4 arcsec half power width (PSPC ~ 25 arcsec) The ROSAT mission comprises three phases: After the initial calibration and verification phase an all sky survey is carried out during half a year, followed by a period of pointed observations. -

In particular, we are interested in the intermediate-duration bursts (shell flashes fueled by thick helium piles) with the ill-understood phenomenon of strong flux fluctuations. Nine such bursts have been discussed in the literature to date. Swift is particularly suitable for finding additional examples. We find and list a total of 134 X-ray bursts; 44 are detected with BAT only, 41 with XRT only, and 49 with both. Twenty-eight bursts involve automatic slews. We find 12 intermediate-duration bursts, all detected in observations involving automatic slews. Five show remarkably long Eddington-limited phases in excess of 200 s. Five show fluctuations during the decay phase; four of which are first discussed in the present study. -
