We have studied the morphologies of infrared-luminous galaxies at 0.3 ≤ z 1011 L☉]. We find that the high-redshift samples are dominated by galaxies with concentrations similar to local late-type disk galaxies; however, they are significantly more asymmetric than most local galaxies but are similar in both regards to local LIRGs. On average, the high-redshift infrared-active galaxies are slightly more asymmetric than the less active ones, although they do include a significantly higher portion…

GOODS-Herschel and CANDELS: The Morphologies of Ultraluminous Infrared Galaxies at z ~ 2
Using deep 100 and 160 μm observations in GOODS-South from GOODS-Herschel, combined with high-resolution HST/WFC3 near-infrared imaging from CANDELS, we present the first detailed morphological

We present a morphology study of intermediate-redshift (0.2 < z < 1.2) luminous infrared galaxies (LIRGs) and general field galaxies in the GOODS fields using a revised asymmetry measurement method
The Environment on a Few Mpc Scales of Infrared Luminous Galaxies at Redshift z~1
We investigate the environment of infrared-luminous galaxies [ -->LIR(8–1000 μ m) > 1011 L☉]. We focus on the redshift range -->0.7 ≤ z≤ 1, where these galaxies dominate the star formation activity

The Oxygen Abundances of Luminous and Ultraluminous Infrared Galaxies
Luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) dominate the star formation rate budget of the universe at -->z 1, yet no local measurements of their heavy-element abundances exist.
The Tully–Fisher relation for S0 galaxies
We present a study of the local B- and Ks-band Tully–Fisher relation (TFR) between absolute magnitude and maximum circular speed in S0 galaxies. To make this study, we have combined kinematic data,

Black Hole Accretion in Low-Mass Galaxies since z ~ 1
We have selected a sample of X-ray-emitting active galactic nuclei (AGNs) in low-mass host galaxies (~5 × 109-2 × 1010 M☉) out to z ~ 1. By comparing to AGNs in more massive hosts, we have found that
