CoRGI in MaNGA - II. NGC 5717: cold-gas accretion and disk growth in a BGG
Damir Gasymov, Ivan Yu. Katkov, Eva K. Grebel +6
Large-scale stellar counter-rotation, in which two coplanar stellar components rotate in opposite directions, is usually interpreted as a signature of external gas accretion. Such…
The galactic HI-to-halo mass relation from isolated galaxies to cosmological hydrodynamic simulations
Marie Korsaga, Jonathan Freundlich, Benoit Famaey +15
The relation between HI and dark matter (DM) halo masses provides key insights into gas accretion and the regulation of galaxy formation. In a previous study based on SPARC and LIT…
Non-linear halo bias for accurate modelling of cosmic infrared background anisotropies
Baptiste Jego, Matthieu Béthermin, Katarina Kraljic +3
Halo models provide the standard framework for interpreting cosmic infrared background (CIB) anisotropies and inferring the connection between dusty star-forming galaxies and their…
Anisotropy of Satellite Galaxies-I: Contrasting Correlations with Central Galaxy, Host Halo, and Large-Scale Filament Structures
Zhuoming Zhang, Weiguang Cui, Yun Chen +2
Using the SIMBA, EAGLE, and IllustrisTNG-100 galaxy formation simulations, we examine the anisotropy of the satellite distribution and its dependencies on central galaxies, host ha…
The Evolution of the Spin Alignments of Dark Matter Halos in the Cosmic Web
David Tobar, Rory Smith, Antonio Montero-Dorta +2
We investigate the evolution of dark matter halo spin alignments with respect to cosmic filaments, exploring how halo mass, proximity to filaments, and major mergers influence thei…
Downsizing does not extend to dwarf galaxies: identifying the stellar mass regimes shaped by supernova and AGN feedback
Ilin Lazar, Sugata Kaviraj, Garreth Martin +10
We explore how the fraction of red (quenched) galaxies varies in the dwarf galaxy regime (10^7 MSun < Mstar < 10^9.5 MSun), using a mass-complete sample of ~5900 dwarfs at z<0.15,…
