Report of the Topical Group on Cosmic Probes of Dark Matter for Snowmass 2021
Alex Drlica-Wagner, Chanda Prescod-Weinstein, Hai-Bo Yu +37
Cosmological and astrophysical observations currently provide the only robust, positive evidence for dark matter. Cosmic probes of dark matter, which seek to determine the fundamen…
Uncovering dark matter density profiles in dwarf galaxies with graph neural networks
Tri Nguyen, Siddharth Mishra-Sharma, Reuel Williams +1
Dwarf galaxies are small, dark matter-dominated galaxies, some of which are embedded within the Milky Way. Their lack of baryonic matter (e.g., stars and gas) makes them perfect te…
Inferring subhalo effective density slopes from strong lensing observations with neural likelihood-ratio estimation
Gemma Zhang, Siddharth Mishra-Sharma, Cora Dvorkin
Strong gravitational lensing has emerged as a promising approach for probing dark matter models on sub-galactic scales. Recent work has proposed the subhalo effective density slope…
A Stimulating Explanation of the Extragalactic Radio Background
Andrea Caputo, Hongwan Liu, Siddharth Mishra-Sharma +2
Despite an intense theoretical and experimental effort over the past decade, observations of the extragalactic radio background at multiple frequencies below 10 GHz are not underst…
Strong Lensing Source Reconstruction Using Continuous Neural Fields
Siddharth Mishra-Sharma, Ge Yang
From the nature of dark matter to the rate of expansion of our Universe, observations of distant galaxies distorted through strong gravitational lensing have the potential to answe…
Machine Learning and Cosmology
Cora Dvorkin, Siddharth Mishra-Sharma, Brian Nord +8
Methods based on machine learning have recently made substantial inroads in many corners of cosmology. Through this process, new computational tools, new perspectives on data colle…
Snowmass2021: Vera C. Rubin Observatory as a Flagship Dark Matter Experiment
Yao-Yuan Mao, Annika H. G. Peter, Susmita Adhikari +30
Establishing that Vera C. Rubin Observatory is a flagship dark matter experiment is an essential pathway toward understanding the physical nature of dark matter. In the past two de…
Snowmass2021 Cosmic Frontier White Paper: Puzzling Excesses in Dark Matter Searches and How to Resolve Them
Rebecca K. Leane, Seodong Shin, Liang Yang +36
Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Ast…
Astrophysical and Cosmological Probes of Dark Matter
Kimberly K. Boddy, Mariangela Lisanti, Samuel D. McDermott +16
While astrophysical and cosmological probes provide a remarkably precise and consistent picture of the quantity and general properties of dark matter, its fundamental nature remain…
