Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics
Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33
Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…
The Sensitivity of Substructure Lensing to SIDM Core-collapse Model Variation
Charlie Mace, Birendra Dhanasingham, Zhichao Carton Zeng +4
Strong gravitational lensing has emerged as a powerful probe of dark matter substructure, and shows particularly strong promise as a test of self-interacting dark matter (SIDM). Th…
Limits of self-interacting neutrinos from the BAO and CMB phase shift
Abbé M. Whitford, Cullan Howlett, Tamara M. Davis +2
Neutrinos with Standard Model interactions free-stream in the early Universe, leaving a distinct phase shift in the pattern of baryon acoustic oscillations (BAO). When isolated, th…
Astrophysical Tests of Dark Matter Self-Interactions
Susmita Adhikari, Arka Banerjee, Kimberly K. Boddy +11
Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the Standard Model that have dark sectors with light mediators or strong dynamics. The self-i…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Satellite Galaxies
Jonah C. Rose, Mariangela Lisanti, Paul Torrey +24
We analyze the properties of satellite galaxies around 1,024 Milky Way-mass hosts from the DREAMS Project, simulated within a CDM cosmology. Utilizing the TNG galaxy-formation…
Neural posterior estimation of the line-of-sight and subhalo populations in galaxy-scale strong lensing systems
Birendra Dhanasingham, Francis-Yan Cyr-Racine, Daniel Gilman
Strong gravitational lensing is a powerful probe for studying the fundamental properties of dark matter on sub-galactic scales. Detailed analyses of galaxy-scale lenses have reveal…
