Feedback driven interactions between dark and luminous matter to explain tight galaxy scaling relations
Leen Alrawas, Andrea V. Macciò, Carlo Cannarozzo
The tight empirical correlation linking the stellar disk scale length to the dark matter scale radius has been proposed as possible evidence for a fundamental coupling…
Empirical estimates of how massive galaxies can be in ÎCDM
Miguel EnrÃquez-Vargas, Aldo RodrÃguez-Puebla, Aditya Manuwal +3
Using Extreme Value Statistics applied to the observed galaxy stellar mass and the UV luminosity functions, we empirically estimate masses and luminosities of the most extreme gala…
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…
On matching galaxy number densities to reconstruct galaxy evolutionary tracks
Aldo Rodriguez-Puebla, Vladimir Avila-Reese, Joel R. Primack +1
The cumulative number density matching approach equates number densities between adjacent redshifts to derive empirical galaxy evolution tracks from the observed galaxy stellar mas…
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…
Gas accretion at high redshift: cold flows all the way
Stefan Waterval, Carlo Cannarozzo, Andrea V. Macciò
We study in detail how massive galaxies accrete gas through cosmic time using cosmological hydrodynamical simulations from the High-z Evolution of Large and Luminous Objects (HELLO…
