In the wake of dark giants: new signatures of dark matter self-interactions in equal-mass mergers of galaxy clusters [PDF]
Author(s): Kim, SY; Peter, AHG; Wittman, D | Abstract: © 2017 The Authors. Merging galaxy clusters have been touted as one of the best probes for constraining selfinteracting darkmatter, but fewsimulations exist to back up this claim.

ABSTRACT As the urgency to address global crises such as climate change and inequality intensifies, the concept of regenerative development has emerged as a transformative approach going beyond sustainability to actively restore and enhance both ecological and social systems.

Apparent Effect of Dust Extinction on the Observed Outflow Velocity of Ionized Gas in Galaxy Mergers
In this study, we examine photoionization outflows during the late stages of galaxy mergers, with a specific focus on the relation between the observed velocity of outflowing gas and the apparent effects of dust extinction.

Origins of the Evil Eye: M64's Stellar Halo Reveals the Recent Accretion of an SMC-mass Satellite
M64, often called the “Evil Eye” galaxy, is unique among local galaxies. Beyond its dramatic, dusty nucleus, it also hosts an outer gas disk that counter-rotates relative to its stars.

From Discs to Bulges: effect of mergers on the morphology of galaxies [PDF]
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 ...

Massive close pairs measure rapid galaxy assembly in mergers at high redshift [PDF]
We compare mass-selected close pairs at z > 1 with the intrinsic galaxy merger rate in the Illustris Simulations. To do so, we construct three 140 arcmin^2 lightcone catalogs and measure pair fractions, finding that they change little or decrease with ...

Sersic properties of disc galaxy mergers [PDF]
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.

LGBTQ+ Affirmative Care Training in Counselor Education: A Community‐Based Inquiry
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+

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