Handy Relation between Binary Black Hole Merger Times and Host Galaxy Properties [PDF]

open access: greenThe Astrophysical Journal Letters
Over the past 15 yr, the evidence has clearly demonstrated that massive black hole (MBH) binary merger timescales depend strongly on the structural and kinematic properties of their host galaxy.

Isolated Galaxies versus Interacting Pairs with MaNGA

open access: yesGalaxies, 2015
We present preliminary results of the spectral analysis on the radial distributions of the star formation history in both a galaxy merger and a spiral isolated galaxy observed with MaNGA.

Starbursts in multiple galaxy mergers [PDF]

open access: yesThe Astrophysical Journal, 2000
We numerically investigate stellar and gaseous dynamical evolution of mergers between five identical late-type disk galaxies with the special emphasis on star formation history and chemical evolution of multiple galaxy mergers.

The Merger Rate of Massive Galaxies [PDF]

open access: bronzeThe Astrophysical Journal, 2006
We calculate the projected two point correlation function for samples of luminous and massive galaxies in the COMBO-17 photometric redshift survey, focusing particularly on the amplitude of the correlation function at small projected radii and exploring the constraints such measurements can place on the galaxy merger rate.

Deep Learning for Galaxy Mergers in the Galaxy Main Sequence [PDF]

open access: yesProceedings of the International Astronomical Union, 2019
Starburst galaxies are often found to be the result of galaxy mergers. As a result, galaxy mergers are often believed to lie above the galaxy main sequence: the tight correlation between stellar mass and star formation rate.

A New Dissociative Galaxy Cluster Merger: RM J150822.0+575515.2

open access: goldThe Astrophysical Journal
Galaxy cluster mergers that exhibit clear dissociation between their dark matter, intracluster gas, and stellar components are great laboratories for probing dark matter properties.

Galaxy Mergers Moulding The Cgm

open access: green, 2017
Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and the extra-galactic medium. However, our understanding of how galaxy mergers, a major evolutionary transformation, impact the CGM remains deficient.

Galaxy mergers in a fractal cosmology

open access: yesEuropean Physical Journal C: Particles and Fields
This work discusses the influence of galaxy mergers in the evolution of a parabolic Lemaître–Tolman–Bondi (LTB) cosmology with simultaneous big bang endowed with two consecutive single fractal galaxy distributions systems possessing fractal dimension D ...

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.

Galaxy cluster mergers [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We present the results of an Eulerian adaptive mesh refinement (AMR) hydrodynamical and N-body simulation in a $ $CDM cosmology. The simulation incorporates common cooling and heating processes for primordial gas. A specific halo finder has been designed and applied in order to extract a sample of galaxy clusters directly obtained from the simulation ...
