Two tails in NGC 3656, and the major merger origin of shell and minor axis dust lane ellipticals [PDF]

open access: yes, 1997
I report on the discovery of two faint (~ 26.8 Rmag/arcsec^2) tidal tails around the shell elliptical NGC 3656 (Arp 155). This galaxy had previously been interpreted as a case of accretion, or minor merger.

Mergers of Luminous Early-Type Galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
Galaxy mergers play an important role in many astrophysical processes, such as growth of massive galaxies, triggering AGN, formation of supermassive black hole (SMBH) binaries, and gravitational wave (GW) radiation. Merger rate is one of key quantities for these studies.

THE LOCAL DWARF GALAXIES:BUILDING BLOCKS OFMASSIVE ONES? I.THE FORNAX DWARF GALAXY

open access: yesOdessa Astronomical Publications, 2008
A chemical evolution of the Local Group dwarf galaxy Fornax is considered in the framework of the merger scenario. We suppose a galactic stellar halo to be formed as separate fragments which then merge; thus, we can calculate the set of such the ...

Interacting galaxies and mergers

open access: yesNature Astronomy, 2019
Two landmark papers in the 1970s contributed strongly to establishing the importance of galaxy interactions and mergers in the formation and evolution of galaxies, using only gravity, and the ensuing dynamical friction.

Ultraluminous Infrared Galaxies: Mergers of Sub‐L* Galaxies? [PDF]

open access: yesThe Astrophysical Journal, 2001
A sample of 27 low-redshift, mostly cool, ultraluminous infrared galaxies (ULIRGs) has been imaged at 1.6 μm with the Hubble Space Telescope (HST) Near-Infrared Camera and Multi-Object Spectrometer (NICMOS). The majority (67%) of the sample's galaxies are multiple-nucleus galaxies with projected separations of up to 17 kpc, and the rest of the sample ...

Galaxy Zoo: Major Galaxy Mergers Are Not a Significant Quenching Pathway* [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract We use stellar mass functions to study the properties and the significance of quenching through major galaxy mergers. In addition to SDSS DR7 and Galaxy Zoo 1 data, we use samples of visually selected major galaxy mergers and post-merger galaxies.

The Dragonfly Galaxy. III. Jet Brightening of a High-redshift Radio Source Caught in a Violent Merger of Disk Galaxies

open access: yesThe Astrophysical Journal, 2023
The Dragonfly galaxy (MRC 0152-209), the most infrared-luminous radio galaxy at redshift z ∼ 2, is a merger system containing a powerful radio source and large displacements of gas.

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 ...

Origin and Evolution of Dust-obscured Galaxies in Galaxy Mergers

open access: yesThe Astrophysical Journal, 2022
Abstract Dust-obscured galaxies (DOGs), which are observationally characterized as faint in the optical and bright in the infrared, are the final stage of galaxy mergers and are essential objects in the evolution of galaxies and active galactic nuclei (AGNs).
