The First Systematic Survey of Stellar Halos in High-Inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies
Bojun Tao, Hong-Xin Zhang, Wenting Wang +8
Stellar halos are the only major stellar component of disk galaxies that lack systematic observational characterization, yet they encode critical information about galaxy merger hi…
Reaching for the Edge II: Stellar Halos out to Large Radii as a Tracer of Dark Matter Halo Mass
Katya Leidig, Benedikt Diemer, Song Huang +3
The diffuse outskirts of brightest cluster galaxies (BCGs) encode valuable information about the assembly history and mass of their host dark matter halos. However, the low surface…
Testing the Stellar Feedback-driven Breathing Mode in Low-mass Galaxies with Gas Kinematics
Yifei Luo, Joseph Wick, Alexie Leauthaud +7
Hydrodynamic simulations have proposed that stellar feedback and bursty star-formation can produce dark matter cores in low-mass galaxies. A key prediction is that feedback-driven…
Improving Galaxy Cluster Selection with the Outskirt Stellar Mass of Galaxies
Matthew Kwiecien, Tesla Jeltema, Alexie Leauthaud +53
The number density and redshift evolution of optically selected galaxy clusters offer an independent measurement of the amplitude of matter fluctuations, . However, recent res…
Relationship between 2D and 3D Galaxy Stellar Mass and Correlations with Halo Mass
Conghao Zhou, Alexie Leauthaud, Shuo Xu +8
Recent studies suggest that the stars in the outer regions of massive galaxies trace halo mass better than the inner regions and that an annular stellar mass provides a low scatter…
