The Effect of Splashback on Weak Lensing Mass Estimates of Galaxy Clusters and Groups
Yuanyuan Zhang, Susmita Adhikari, Matteo Costanzi +3
The splashback radius of a dark matter halo, which corresponds to the first apocenter radius reached by infalling matter and substructures, has been detected around galaxy clusters…
Symphony: Cosmological Zoom-in Simulation Suites over Four Decades of Host Halo Mass
Ethan O. Nadler, Philip Mansfield, Yunchong Wang +9
We present Symphony, a compilation of cosmological, cold-dark-matter-only zoom-in simulations spanning four decades of host halo mass, from $10^{15}~M_{\mathrm{\o…
A Better Way to Define Dark Matter Haloes
Rafael Garcia, Edgar Salazar, Eduardo Rozo +5
Dark matter haloes have long been recognized as one of the fundamental building blocks of large scale structure formation models. Despite their importance -- or perhaps because of…
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…
Observational Inference on the Delay Time Distribution of Short Gamma-ray Bursts
Michael Zevin, Anya E. Nugent, Susmita Adhikari +3
The delay time distribution of neutron star mergers provides critical insights into binary evolution processes and the merger rate evolution of compact object binaries. However, cu…
Insights into the origin of halo mass profiles from machine learning
Luisa Lucie-Smith, Susmita Adhikari, Risa H. Wechsler
The mass distribution of dark matter haloes is the result of the hierarchical growth of initial density perturbations through mass accretion and mergers. We use an interpretable ma…
Accurate Model of the Projected Velocity Distribution of Galaxies in Dark Matter Halos
Han Aung, Daisuke Nagai, Eduardo Rozo +2
We present a percent-level accurate model of the line-of-sight velocity distribution of galaxies around dark matter halos as a function of projected radius and halo mass. The model…
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: Dark Matter Physics from Halo Measurements
Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine +41
The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, an…
Dark Energy Survey Year 3 Results: Three-Point Shear Correlations and Mass Aperture Moments
L. F. Secco, M. Jarvis, B. Jain +87
We present high signal-to-noise measurements of three-point shear correlations and the third moment of the mass aperture statistic using the first 3 years of data from the Dark Ene…
