The Connection between Halo Assembly History and the Stellar Distribution I: The Central Stellar Mass - Richness Plane
Shuo Xu, Song Huang, Alexie Leauthaud +4
Recent observations suggest intrinsic links between the stellar components of massive halos and their assembly histories. Using massive halos with $\log[M_{\rm halo}/M_\odot] \geq…
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 ΛCDM
Miguel Enríquez-Vargas, Aldo Rodríguez-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…
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…
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…
Non-Monotonic Relations of Galaxy Star Formation, Radius, and Structure at Fixed Stellar Mass
Jimena Stephenson, Aldo Rodriguez-Puebla, S. M. Faber +9
We investigate the relation between galaxy structure and star formation rate (SFR) in a sample of central galaxies with and axial ratios .…
The evolution of radial gradients of MaNGA quiescent elliptical galaxies: inside-out quenching or outer mass growth?
V. Avila-Reese, H. Ibarra-Medel, I. Lacerna +5
Using spatially-resolved fossil record analysis on a large sample of 'red and dead' elliptical galaxies (classical ellipticals, CLEs) from the MaNGA/SDSS-IV DR15 survey, we reconst…
The Contribution of In-situ and Ex-situ Star Formation in Early-Type Galaxies: MaNGA versus IllustrisTNG
Carlo Cannarozzo, Alexie Leauthaud, Grecco A. Oyarzún +6
We compare stellar mass surface density, metallicity, age, and line-of-sight velocity dispersion profiles in massive () present-day early-type g…
Stellar velocity dispersion and initial mass function gradients in dissipationless galaxy mergers
Carlo Nipoti, Carlo Cannarozzo, Francesco Calura +2
The stellar initial mass function (IMF) is believed to be non-universal among early-type galaxies (ETGs). Parameterizing the IMF with the so-called IMF mismatch parameter $α_{\rm I…
The merger-driven evolution of massive early-type galaxies
Carlo Cannarozzo, Carlo Nipoti, Alessandro Sonnenfeld +4
The evolution of the structural and kinematic properties of early-type galaxies (ETGs), their scaling relations, as well as their stellar metallicity and age contain precious infor…
The cosmic evolution of the stellar massvelocity dispersion relation of early-type galaxies
Carlo Cannarozzo, Alessandro Sonnenfeld, Carlo Nipoti
We study the evolution of the observed correlation between central stellar velocity dispersion and stellar mass of massive ($M_*\gtrsim 3\times 10^{10}\,\mathr…
