The Outskirt Stellar Mass of Low-Redshift Massive Galaxies is an Excellent Halo Mass Proxy in Illustris/IllustrisTNG Simulations
Shuo Xu, Song Huang, Alexie Leauthaud +4
Recent observations suggest that the extended stellar halos of low-redshift massive galaxies are tightly connected to the assembly of their dark matter halos. In this paper, we use…
The mass-dependent UVJ diagram at cosmic noon: A challenge for galaxy evolution models and dust radiative transfer
Andrea Gebek, Benedikt Diemer, Marco Martorano +9
Context. The UVJ color-color diagram is a widely used diagnostic to separate star-forming and quiescent galaxies. Observational data from photometric surveys reveal a strong stella…
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…
A Multi-Wavelength Technique for Estimating Galaxy Cluster Mass Accretion Rates
John Soltis, Michelle Ntampaka, Benedikt Diemer +7
The mass accretion rate of galaxy clusters is a key factor in determining their structure, but a reliable observational tracer has yet to be established. We present a state-of-the-…
A dynamics-based density profile for dark haloes -- III. Parameter space
Benedikt Diemer
In the previous paper of this series, we proposed a new function to fit halo density profiles out to large radii. This truncated Einasto profile models the inner, orbiting matter a…
