LINEAR SUBSTRUCTURES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2019 We propose detailed scheme that is describing the morphology of linear substructures in galaxy clusters. Our base morphological scheme di- vides galaxy clusters using numerical criteria according the parameters: concentration to the cluster center, the ...

Witnessing the growth of the nearest galaxy cluster [PDF]
, 2016 We present results from Suzaku Key Project observations of the Virgo Cluster, the nearest galaxy cluster to us, mapping its X-ray properties along four long `arms' extending beyond the virial radius.

3D-Matched-Filter Galaxy Cluster Finder I: Selection Functions and CFHTLS Deep Clusters [PDF]
, 2009 We present an optimised galaxy cluster finder, 3D-Matched-Filter (3D-MF), which utilises galaxy cluster radial profiles, luminosity functions and redshift information to detect galaxy clusters in optical surveys.

Mass Distribution in Galaxy Cluster Cores [PDF]
, 2016 Many processes within galaxy clusters, such as those believed to govern the onset of thermally unstable cooling and active galactic nucleus feedback, are dependent upon local dynamical timescales. However, accurate mapping of the mass distribution within

Dark matter phenomenology of high-speed galaxy cluster collisions
European Physical Journal C: Particles and Fields, 2017 We perform a general computational analysis of possible post-collision mass distributions in high-speed galaxy cluster collisions in the presence of self-interacting dark matter.

THE UBIQUITY OF COEVAL STARBURSTS IN MASSIVE GALAXY CLUSTER PROGENITORS [PDF]
, 2016 The universe’s largest galaxy clusters likely built the majority of their massive >1011 M galaxies in simultaneous, short-lived bursts of activity well before virialization.

The Galaxy Cluster Merger Catalog: An Online Repository of Mock Observations from Simulated Galaxy Cluster Mergers [PDF]
, 2016 We present the “Galaxy Cluster Merger Catalog.” This catalog provides an extensive suite of mock observations and related data for N-body and hydrodynamical simulations of galaxy cluster mergers and clusters from cosmological simulations.

Unidentified line in x-ray spectra of the Andromeda galaxy and Perseus galaxy cluster. [PDF]
Physical Review Letters, 2014 We report a weak line at 3.52±0.02 keV in x-ray spectra of the Andromeda galaxy and the Perseus galaxy cluster observed by the metal-oxide-silicon (MOS) and p-n (PN) CCD cameras of the XMM-Newton telescope.

THE DETERMINATION OF THE MORPHOLOGICAL TYPES OF GALAXY CLUSTERS USING CLUSTER CARTOGRAPHY
Odessa Astronomical Publications, 2016 We discuss the possibility of using the Cluster Cartography set for the determined the morphological types of galaxy clusters. The applied morphological scheme was proposed by Panko (2013).
