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.

Alignment of galaxies and clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We investigated the influence of environment on cluster galaxies by examining the alignment of the brightest cluster galaxy (BCG) position angle with respect to the host cluster X-ray position angle. The cluster position angles were measured using high spatial resolution X-ray data taken from the Chandra ACIS archive, that significantly improved the ...

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. We find that there exists a characteristic scale where the properties of galaxies suddenly start to depend on the clustercentric radius at fixed ...

Cluster-counterpart Voids: Void Identification from Galaxy Density Field
The Astrophysical Journal, 2023 We identify cosmic voids from galaxy density fields under the theory of void–cluster correspondence. We extend the previous novel void-identification method developed for the matter density field to the galaxy density field for practical applications ...

Accretion of galaxy groups into galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼ 1014 $\rm M_\odot$ from the cosmological hydrodynamical simulation Illustris and follow their galaxies with stellar mass M⋆ ≥ 1.5 × 108 $\rm M_\odot$.

ON THE DETERMINATION OF GALAXY STRUCTURE ELLIPTICITY
Odessa Astronomical Publications, 2007 We discuss factors influencing the determination of the observed shape of galaxy clusters when the covariance ellipse method is involved. The analysis of 377 Abell clusters show that at greater distances from the cluster center the ellipticity is rather ...

The Astrophysical Journal, 2023 Active galactic nuclei (AGNs) are widely believed to be one of the promising acceleration sites of ultrahigh-energy cosmic rays (CRs). Essentially, AGNs are powered by the gravitational energy of matter falling into supermassive black holes. However, the
