Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Alex Drlica-Wagner, Chanda Prescod-Weinstein, Hai-Bo Yu, Andrea Albert, Arka Banerjee | Summary: Cosmological and astrophysical observations currently provide the the only robust, positive evidence for dark matter. Cosmic probes of dark matter, which seek to determine the fundamental properties of dark matter through observations of the […]
Kavli Affiliate: Daniel S. Akerib | First 5 Authors: Jodi Cooley, Tongyan Lin, W. Hugh Lippincott, Tracy R. Slatyer, Tien-Tien Yu | Summary: This report summarizes the findings of the CF1 Topical Subgroup to Snowmass 2021, which was focused on particle dark matter. One of the most important scientific goals of the next decade is […]

Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Blazars are active galactic nuclei that launch collimated, powerful jets of magnetized relativistic plasma. Their primary jet, whose emission typically spans from low-frequency radio to very high-energy ($gtrsim0.1$ TeV) $gamma$-rays (Blandford […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: David J. Schlegel, Juna A. Kollmeier, Greg Aldering, Stephen Bailey, Charles Baltay | Summary: In this white paper, we present the MegaMapper concept. The MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts at $2<z<5$. In order to achieve […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: David J. Schlegel, Simone Ferraro, Greg Aldering, Charles Baltay, Segev BenZvi | Summary: In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 million galaxies and quasars and capturing […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Philip Mansfield, Yunchong Wang, Xiaolong Du, Susmita Adhikari | Summary: We present Symphony, a compilation of $262$ cosmological, cold dark matter-only zoom-in simulations spanning four decades of host halo mass, from $10^{11}~M_{mathrm{odot}}$ to $10^{15}~M_{mathrm{odot}}$. This compilation includes three existing simulation suites at the […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Brittany E. Miles, Beth A. Biller, Polychronis Patapis, Kadin Worthen, Emily Rickman | Summary: We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a $<$20 M$_mathrm{Jup}$ widely separated ($sim$8arcsec, a = 150 au), young, planetary-mass companion that shares photometric colors […]
