Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster [PDF]

, 2018
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a subset of galaxy clusters.

Velocity Dispersion of 335 Galaxy Clusters Selected from the Sloan Digital Sky Survey: Statistical Evidence for Dynamical Interaction, and Against Ram-Pressure Stripping [PDF]

Mon.Not.Roy.Astron.Soc. 359 (2005) 1415-1420, 2005
There has been plenty of observational evidence of cluster galaxy evolution. However, it has been difficult to identify the origin of the cluster galaxy evolution. Here we show that gravitational interaction/friction between galaxies is the statistically dominant physical mechanism responsible for the cluster galaxy evolution, and that the well-favored

Galaxy cluster mergers [PDF]

Monthly 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 $\Lambda$CDM cosmology. The simulation incorporates common cooling and heating processes for primordial gas.

Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm [PDF]

The Astrophysical Journal
We present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities.

The rotation of Galaxy Clusters [PDF]

Published in Astrofizika, Vol. 58, No. 3, pp. 353-363 (August 2014), 2015
The method for detection of the galaxy cluster rotation based on the study of distribution of member galaxies with velocities lower and higher of the cluster mean velocity over the cluster image is proposed. The search for rotation is made for flat clusters with $a/b>1.8$ and BMI type clusters which are expected to be rotating.

Interactions of Galaxies in the Galaxy Cluster Environment [PDF]

The Astrophysical Journal, 2009
We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the SDSS galaxies associated with the Abell galaxy clusters.

Contrasting distributions and expression characteristics of transcribing repeats in Setaria viridis. [PDF]

Plant Genome
Abstract Repetitive DNA contributes significantly to plant genome size, adaptation, and evolution. However, little is understood about the transcription of repeats. This is addressed here in the plant green foxtail millet (Setaria viridis). First, we used RepeatExplorer2 to calculate the genome proportion (GP) of all repeat types and compared the GP of

Enhanced sensitivity of TAPscan v4 enables comprehensive analysis of streptophyte transcription factor evolution. [PDF]

Plant J
SUMMARY Transcription‐associated proteins (TAPs) fulfill multiple functions in regulatory and developmental processes and display lineage‐specific evolution. TAPscan is a comprehensive and highly reliable tool for genome‐wide TAP annotation via domain profiles.

THE ORIENTATION OF GALAXIES IN GALAXY CLUSTERS [PDF]

The Astrophysical Journal, 2010
We present an analysis of the spatial orientations of galaxies in the 247 optically selected rich Abell clusters, having in the considered area at least 100 members. We investigated the relation between angles giving information about galaxy angular momenta and the number of members in each structure.
