The green valley is a red herring: Galaxy Zoo reveals two evolutionary pathways towards quenching of star formation in early-and late-type galaxies

K Schawinski, CM Urry, BD Simmons… - Monthly Notices of …, 2014 - academic.oup.com
Abstract We use SDSS+ GALEX+ Galaxy Zoo data to study the quenching of star formation
in low-redshift galaxies. We show that the green valley between the blue cloud of star …

Galaxy pairs in the Sloan Digital Sky Survey–IV. Interactions trigger active galactic nuclei

SL Ellison, DR Patton, JT Mendel… - Monthly Notices of the …, 2011 - academic.oup.com
Galaxy–galaxy interactions are predicted to cause gas inflows leading to enhanced nuclear
star formation. This prediction is borne out observationally, and is also supported by the gas …

The diversity and variability of star formation histories in models of galaxy evolution

KG Iyer, S Tacchella, S Genel… - Monthly Notices of …, 2020 - academic.oup.com

Morphology-density relation, quenching, and mergers in CARLA clusters and protoclusters at 1.4< z< 2.8

S Mei, NA Hatch, S Amodeo, AV Afanasiev… - Astronomy & …, 2023 - aanda.org
At redshifts of z≲ 1.3, early-type galaxies (ETGs) and passive galaxies are mainly found in
dense environments, such as galaxy clusters. However, it remains unclear whether these …

The Argo simulation–I. Quenching of massive galaxies at high redshift as a result of cosmological starvation

R Feldmann, L Mayer - Monthly Notices of the Royal …, 2015 - academic.oup.com
Observations show a prevalence of high-redshift galaxies with large stellar masses and
predominantly passive stellar populations. A variety of processes have been suggested that …

Incidence of WISE-selected obscured AGNs in major mergers and interactions from the SDSS

ME Weston, DH McIntosh, M Brodwin… - Monthly Notices of …, 2016 - academic.oup.com
We use the Wide-field Infrared Survey Explorer (WISE) and the Sloan Digital Sky Survey
(SDSS) to confirm a connection between dust-obscured active galactic nuclei (AGNs) and …

Black hole–galaxy scaling relationships for active galactic nuclei with reverberation masses

MC Bentz, E Manne-Nicholas - The Astrophysical Journal, 2018 - iopscience.iop.org
We have utilized high-resolution optical Hubble Space Telescope images and deep, ground-
based near-infrared images to examine the host galaxies of 37 active galactic nuclei (AGNs) …

Galaxy-scale outflows driven by active galactic nuclei

J DeBuhr, E Quataert, CP Ma - Monthly Notices of the Royal …, 2012 - academic.oup.com
We present hydrodynamical simulations of major mergers of galaxies and study the effects
of winds produced by active galactic nuclei (AGN) on interstellar gas in the AGN's host …

Decreased specific star formation rates in AGN host galaxies

TT Shimizu, RF Mushotzky, M Meléndez… - Monthly Notices of …, 2015 - academic.oup.com
