Active galactic nuclei (AGN) are powered by the accretion of material onto a supermassive
black hole (SMBH) and are among the most luminous objects in the Universe. However, the …

Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

In this paper we present the MOSFIRE Deep Evolution Field (MOSDEF) survey. The
MOSDEF survey aims to obtain moderate-resolution (R= 3000-3650) rest-frame optical …

We describe the design and data analysis of the DEEP2 Galaxy Redshift Survey, the
densest and largest high-precision redshift survey of galaxies at z∼ 1 completed to date …

We perform a spectroscopic analysis of 492 450 galaxy spectra from the first two years of
observations of the Sloan Digital Sky Survey (SDSS) III/Baryonic Oscillation Spectroscopic …

The shutdown of star formation in galaxies is generally termed" quenching." Quenching may
occur through a variety of processes, eg, active galactic nucleus (AGN) feedback, stellar …

Passive red galaxies frequently contain warm ionized gas and have spectra similar to low-
ionization nuclear emission-line regions (LINERs). Here we investigate the nature of the …

We present results from the MOSFIRE Deep Evolution Field (MOSDEF) survey on rest-frame
optical active galactic nucleus (AGN) identification and completeness at z∼ 2.3. With our …

ABSTRACT We introduce the Mass-Excitation (MEx) diagnostic to identify active galactic
nuclei (AGNs) in galaxies at intermediate redshift. In the absence of near-infrared …

ABSTRACT We use 317,000 emission-line galaxies from the Sloan Digital Sky Survey to
investigate line-ratio selection of active galactic nuclei (AGNs). In particular, we demonstrate …
