PHOTOMETRIC DECOMPOSITION OF MERGERS IN DISK GALAXIES [PDF]
The Astrophysical Journal, 2014 Several observational studies and numerical simulations suggest that mergers must contribute to the evolution of galaxies; however, the role that they play is not yet fully understood. In this paper we study a sample of 52 double nucleus disk galaxies that are considered as candidates for a minor merger event.

Enhanced Star Formation and Black Hole Accretion Rates in Galaxy Mergers in IllustrisTNG50
The Astrophysical JournalMany theoretical and observational studies have suggested that galaxy mergers may trigger enhanced star formation or active galactic nucleus activity.

A Multiwavelength Study of Active Galactic Nuclei in Post-merger Remnants
The Astrophysical Journal, 2023 We investigate the role of galaxy mergers in triggering active galactic nuclei (AGN) in the nearby universe. Our analysis is based on a sample of 79 post-merger remnant galaxies with deep X-ray observations from Chandra/XMM-Newton capable of detecting a ...

Buried AGNs in Advanced Mergers:Mid-infrared color selection as a dual AGN finder
, 2017 A direct consequence of hierarchical galaxy formation is the existence of dual supermassive black holes (SMBHs), which may be preferentially triggered as active galactic nuclei (AGN) during galaxy mergers. Despite decades of searching, however, dual AGNs

From Discs to Bulges: effect of mergers on the morphology of galaxies [PDF]
, 2015 We study the effect of mergers on the morphology of galaxies by means of the simulated merger tree approach first proposed by Moster et al. This method combines N-body cosmological simulations and semi-analytic techniques to extract realistic initial ...

LGBTQ+ Affirmative Care Training in Counselor Education: A Community‐Based Inquiry
Counselor Education and Supervision, EarlyView.ABSTRACT Counselor educators, counselors‐in‐training, and LGBTQ+ community members engaged in a community‐based qualitative inquiry exploring LGBTQ+ affirmative care education. Findings revealed counselor educators’ components and delivery of content, developmental implications for applying LGBTQ+ affirmative care, and gaps between education and LGBTQ+

Intermediate Mass Ratio Inspirals in Milky Way Galaxies
The Astrophysical JournalA consequence of a nonzero occupation fraction of massive black holes (MBHs) in dwarf galaxies is that these MBHs can become residents of larger galaxy halos via hierarchical merging and tidal stripping.

Sersic properties of disc galaxy mergers [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Sersic parameters characterising the density profiles of remnants formed in collision-less disc galaxy mergers are obtained; no bulge is included in our simulations. For the luminous component we find that the Sersic index is n ~ (1.5,5.3) with ~ 3 +/- 1 and an effective radius of R_e ~ (1.6,12.9) kpc with ~ 5 +/- 3 kpc.

Close Pairs as Proxies for Galaxy Cluster Mergers
, 2008 Galaxy cluster merger statistics are an important component in understanding the formation of large-scale structure. Unfortunately, it is difficult to study merger properties and evolution directly because the identification of cluster mergers in ...
