MOST SUBMILLIMETER GALAXIES ARE MAJOR MERGERS [PDF]

open access: yesThe Astrophysical Journal, 2010
We analyse subarcsecond resolution interferometric CO line data for twelve sub-millimetre-luminous (S850um > 5mJy) galaxies with redshifts between 1 and 3, presenting new data for four of them. Morphologically and kinematically most of the twelve systems appear to be major mergers. Five of them are well-resolved binary systems, and seven are compact

A survey of dual active galactic nuclei in simulations of galaxy mergers: frequency and properties [PDF]

open access: yes, 2016
We investigate the simultaneous triggering of active galactic nuclei (AGN) in merging galaxies, using a large suite of high-resolution hydrodynamical simulations.

A semi-analytic model comparison - gas cooling and galaxy mergers [PDF]

open access: yes, 2010
We use stripped-down versions of three semi-analytic galaxy formation models to study the influence of different assumptions about gas cooling and galaxy mergers.

CORRELATION BETWEEN GALAXY MERGERS AND LUMINOUS ACTIVE GALACTIC NUCLEI [PDF]

open access: yes, 2015
It is not yet clear what triggers the activity of active galactic nuclei (AGNs), but galaxy merging has been suspected to be one of the main mechanisms fueling the activity.

Distinguishing Mergers and Disks in High-redshift Observations of Galaxy Kinematics [PDF]

open access: yesAstrophysical Journal, 2019
The majority of massive star-forming galaxies at z ∼ 2 have velocity gradients suggestive of rotation, in addition to large amounts of disordered motions.

Galaxy Zoo: Mergers – Dynamical models of interacting galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2016
The dynamical history of most merging galaxies is not well understood. Correlations between galaxy interaction and star formation have been found in previous studies, but require the context of the physical history of merging systems for full insight into the processes that lead to enhanced star formation.

Dark Matter Halo Mergers I: Dependence on Environment & Redshift Evolution [PDF]

open access: yes, 2009
This paper presents a study of the specific merger rate as a function of group membership, local environment, and redshift in a very large, $500h^{-1} Mpc$, cosmological N-body simulation, the \textit{Millennium Simulation}.

GALAXY MERGERS DRIVE SHOCKS: AN INTEGRAL FIELD STUDY OF GOALS GALAXIES [PDF]

open access: yes, 2015
We present an integral field spectroscopic study of radiative shocks in 27 nearby ultraluminous and luminous infrared galaxies (U/LIRGs) from the Great Observatory All-sky LIRG Survey, a subset of the Revised Bright Galaxy Sample.

Comparison of black hole growth in galaxy mergers with gasoline and ramses [PDF]

open access: yes, 2015
Supermassive black hole dynamics during galaxy mergers is crucial in determining the rate of black hole mergers and cosmic black hole growth. As simulations achieve higher resolution, it becomes important to assess whether the black hole dynamics is ...

The Role Of Mergers In Galaxy Formation

open access: yes, 2017
The combination of high spatial resolution from space and 3D spectroscopy from ground is a remarkable tool to dissect distant galaxies and their internal motions. Combining HST and VLT instruments, it has robustly captured the evolution of the Hubble Sequence since the last 8 billion years.
