Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it
can control the critical process of transforming galaxies from star forming to quiescent …

We investigate the evolution of galaxy gas-phase metallicity (O/H) over the range z= 0–3.3
using samples of∼ 300 galaxies at z∼ 2.3 and∼ 150 galaxies at z∼ 3.3 from the MOSDEF …

Negative feedback from active galactic nuclei (AGN) is the leading mechanism for the
quenching of massive galaxies in the vast majority of modern galaxy evolution models …

We present detections of [O iii] λ4363 and direct-method metallicities for star-forming
galaxies at z= 1.7–3.6. We combine new measurements from the MOSFIRE Deep Evolution …

We present a census of ionized gas outflows in 599 normal galaxies at redshift 0.6< z< 2.7,
mostly based on integral field spectroscopy of Hα,[N ii], and [S ii] line emission. The sample …

Collisions and interactions between gas-rich galaxies are thought to be pivotal stages in
their formation and evolution, causing the rapid production of new stars, and possibly …

The question of whether galaxy mergers are linked to the triggering of active galactic nuclei
(AGN) continues to be a topic of considerable debate. The issue can be broken down into …

We derive a UV-optical stellar dust attenuation curve of galaxies at z= 1.4–2.6 as a function
of gas-phase metallicity. We use a sample of 218 star-forming galaxies, excluding those with …

We perform joint modeling of the composite rest-frame far-UV and optical spectra of redshift
1.85≤ z≤ 3.49 star-forming galaxies to deduce key properties of the massive stars, ionized …

Despite solid theoretical and observational grounds for the pairing of supermassive black
holes (SMBHs) after galaxy mergers, definitive evidence for the existence of close (sub …
