The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective

open access: yesUniverse, 2022
Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

Growing supermassive black holes in the late stages of galaxy mergers are heavily obscured [PDF]

open access: yes, 2017
Mergers of galaxies are thought to cause significant gas inflows to the inner parsecs, which can activate rapid accretion on to supermassive black holes (SMBHs), giving rise to active galactic nuclei (AGN). During a significant fraction of this process,

Real galaxy mergers from galaxy pair catalogues [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Mergers of galaxies are extremely violent events shaping their evolution. Such events are thought to trigger starbursts and, possibly, black hole accretion. Nonetheless, it is still not clear how to know the fate of a galaxy pair from the data available at a given time, limiting our ability to constrain the exact role of mergers.

Building the red sequence through gas-rich major mergers [PDF]

open access: yes, 2009
Understanding the details of how the red sequence is built is a key question in galaxy evolution. What are the relative roles of gas-rich vs. dry mergers, major vs. minor mergers or galaxy mergers vs. gas accretion? In Wild et al.

Constraining the galaxy–halo connection over the last 13.3 Gyr: star formation histories, galaxy mergers and structural properties [PDF]

open access: yes, 2017
We present new determinations of the stellar-to-halo mass relation (SHMR) at $z=0-10$ that match the evolution of the galaxy stellar mass function, the SFR$-M_*$ relation,and the cosmic star formation rate.

The Origin of Double-peaked Narrow Lines in Active Galactic Nuclei. IV. Association with Galaxy Mergers [PDF]

open access: yesAstrophysical Journal, 2018
Double-peaked narrow emission lines in active galactic nucleus (AGN) spectra can be produced by AGN outflows, rotation, or dual AGNs, which are AGN pairs in ongoing galaxy mergers.

Simulations of Galaxy Mergers [PDF]

open access: yesSymposium - International Astronomical Union, 1983
The last few years have seen a considerable amount of effort devoted to the problem of simulating the coalescence of galaxies. After a discussion of the merits and limitations of the N-body techniques that have been used, I summarise the insight this research gives into the mechanisms driving strong interactions in galaxy collisions and into the ...

Stellar populations in gas-rich galaxy mergers II. Feedback effects of Type Ia and II supernovae [PDF]

open access: yes, 1998
We numerically investigate chemodynamical evolution of major disk-disk galaxy mergers in order to explore the origin of mass-dependent chemical, photometric, and spectroscopic properties observed in elliptical galaxies.

Back to the Green Valley: How to Rejuvenate an S0 Galaxy through Minor Mergers

open access: yesGalaxies, 2015
About half of the S0 galaxies in the nearby Universe show signatures of recent or ongoing star formation. Whether these S0 galaxies were rejuvenated by the accretion of fresh gas is still controversial.

SDSS-IV MaNGA: How Galaxy Interactions Influence Active Galactic Nuclei

open access: yesThe Astrophysical Journal, 2023
We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release of the MaNGA integral field spectroscopic survey.
