Gentle reenergization of electrons in merging galaxy clusters. [PDF]
Sci Adv, 2017 Cosmic ray electrons reenergized in merging galaxy clusters: A phenomenon observed with low-frequency radio telescopes. Galaxy clusters are the most massive constituents of the large-scale structure of the universe.

Detection of anti-correlation of hot and cold baryons in galaxy clusters [PDF]
Nature Communications, 2019 Galaxy clusters contain vast amount of dark matter and baryonic matter. Here the authors show the observational detection of the anti-correlation of gas mass and stellar mass observables in the most massive galaxy clusters, indicating such clusters ...

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.

Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm [PDF]
The Astrophysical JournalWe present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities.

An excess of small-scale gravitational lenses observed in galaxy clusters [PDF]
Science, 2020 Galaxy clusters contain more small-scale gravitational lenses than expected from cosmological simulations. Gravitational lenses in galaxy clusters The large mass of a galaxy cluster deflects light from background objects, a phenomenon known as ...

The radial acceleration relation in galaxy clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2020 Recently, the discovery of the radial acceleration relation (RAR) in galaxies has been regarded as an indirect support of alternative theories of gravity such as modified Newtonian dynamics (MOND) and modified gravity.

Diffuse Radio Emission from Galaxy Clusters [PDF]
Space Science Reviews, 2019 In a growing number of galaxy clusters diffuse extended radio sources have been found. These sources are not directly associated with individual cluster galaxies.

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.
