Dancing to CHANGA: a self-consistent prediction for close SMBH pair formation time-scales following galaxy mergers [PDF]

open access: yes, 2017
We present the first self-consistent prediction for the distribution of formation timescales for close Supermassive Black Hole (SMBH) pairs following galaxy mergers.

Impact of galaxy mergers on the colours of cluster galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
ABSTRACT We examine the ultraviolet and optical colours of 906 cluster galaxies from the KASI-Yonsei Deep Imaging Survey of Clusters (KYDISC). The sample has been divided into two categories, morphologically disturbed and undisturbed galaxies, based on the visual signatures related to recent mergers. We find that galaxies with signatures

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.

Merger relics of cluster galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2013
Context. Sheen and collaborators recently found that a surprisingly large portion (38%) of massive early-type galaxies in heavy clusters show strong merger-related disturbed features. This contradicts the general understanding that massive clusters are hostile environments for galaxy mergers. Considering the significance of mergers in galaxy evolution,

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.

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

open access: yes, 2017
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.

Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX) [PDF]

open access: yesEPJ Web of Conferences
Galaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster medium.

A Chandra X-Ray Survey of Optically Selected Close Galaxy Pairs: Unexpectedly Low Occupation of Active Galactic Nuclei

open access: yesThe Astrophysical Journal, 2023
High-resolution X-ray observations offer a unique tool for probing the still-elusive connection between galaxy mergers and active galactic nuclei (AGNs).

Spatially Offset Active Galactic Nuclei. II. Triggering in Galaxy Mergers [PDF]

open access: yes, 2017
Galaxy mergers are likely to play a role in triggering active galactic nuclei (AGNs), but the conditions under which this process occurs are poorly understood.

Observational Constraints on Correlated Star Formation and Active Galactic Nuclei in Late-stage Galaxy Mergers [PDF]

open access: yes, 2017
Galaxy mergers are capable of triggering both star formation and active galactic nuclei (AGNs) and therefore may represent an important pathway in the co-evolution of galaxies and supermassive black holes (SMBHs).
