A Splashback-like Feature of Central Galaxies in Galaxy Clusters

Yuanyuan Zhang, Susmita Adhikari, Louise O. V. Edwards +3

We investigate a splashback-like feature in the outer region of central galaxies (CGs) in clusters. This feature is detected as a "dip" in the radial slope of the CG surface bright…

The mass profiles of dwarf galaxies from Dark Energy Survey lensing

Joseph Thornton, Alexandra Amon, Risa H. Wechsler +7

We present a novel approach to extracting dwarf galaxies from photometric data to measure their average halo mass profile with weak lensing. We characterise their stellar mass and…

UniverseMachine: Predicting Galaxy Star Formation over Seven Decades of Halo Mass with Zoom-in Simulations

Yunchong Wang, Ethan O. Nadler, Yao-Yuan Mao +3

We apply the empirical galaxy--halo connection model UniverseMachine to dark matter-only zoom-in simulations of isolated Milky Way (MW)--mass halos along with their parent cosmolog…

Probing galaxy evolution in massive clusters using ACT and DES: splashback as a cosmic clock

Susmita Adhikari, Tae-hyeon Shin, Bhuvnesh Jain +113

We measure the projected number density profiles of galaxies and the splashback feature in clusters selected by the Sunyaev--Zeldovich (SZ) effect from the Advanced Atacama Cosmolo…

The binary-host connection: astrophysics of gravitational wave binaries from their host galaxy properties

Susmita Adhikari, Maya Fishbach, Daniel E. Holz +2

Gravitational waves produced from the merger of binary neutron stars (BNSs) are accompanied by electromagnetic counterparts, making it possible to identify the associated host gala…

How Accurately Can We Detect the Splashback Radius of Dark Matter Halos and its Correlation With Accretion Rate?

Enia Xhakaj, Benedikt Diemer, Alexie Leauthaud +5

The splashback radius () of dark matter halos has recently been detected using weak gravitational lensing and cross-correlations with galaxies. However, different metho…

Kinematics of cluster galaxies and their relation to galaxy evolution

Susmita Adhikari, Neal Dalal, Surhud More +1

We study the kinematics of galaxies within massive clusters, as a probe of the physics of star-formation quenching within clusters. Using N-body simulations, we argue that satellit…

Probing Self-interacting Dark Matter with Disk Galaxies in Cluster Environments

Lucas F. Secco, Amanda Farah, Bhuvnesh Jain +3

Self-Interacting Dark Matter (SIDM) has long been proposed as a solution to small scale problems posed by standard Cold Dark Matter (CDM). We use numerical simulations to study the…
