Modeling galaxy formation in a cosmological context presents one of the greatest
challenges in astrophysics today due to the vast range of scales and numerous physical …

As they grow, galaxies can transition from irregular/spheroidal with 'bursty'star formation
histories (SFHs), to discy with smooth SFHs. But even in simulations, the direct physical …

The extragalactic background light (EBL) is of fundamental importance both for
understanding the entire process of galaxy evolution and for γ-ray astronomy, but the overall …

We present evidence for very high gas fractions and extended molecular gas reservoirs in
normal, near-infrared-selected (BzK) galaxies at z∼ 1.5. Our results are based on multi …

Exploiting the deep high-resolution imaging of all five CANDELS fields, and accurate
redshift information provided by 3D-HST, we investigate the relation between structure and …

We use multiscale smoothed particle hydrodynamic simulations to study the inflow of gas
from galactic scales (∼ 10 kpc) down to≲ 0.1 pc, at which point the gas begins to resemble …

The most common means of converting an observed CO line intensity into a molecular gas
mass requires the use of a conversion factor (X CO). While in the Milky Way this quantity …

We use a suite of semi-empirical models to predict the galaxy–galaxy merger rate and
relative contributions to bulge growth as a function of mass (both halo and stellar), redshift …

Mergers and the spin of the dark matter halo are factors traditionally believed to determine
the morphology of galaxies within a Λ cold dark matter (ΛCDM) cosmology. We study this …

We implement physically motivated recipes for partitioning cold gas into different phases
(atomic, molecular, and ionized) in galaxies within semi-analytic models of galaxy formation …
