We investigated the properties of galaxy clusters in the region of the Hercules supercluster using observational data from the SDSS and 2MASS catalogs and the NED. We have selected 13 galaxy clusters with a total dynamical mass of 4.82 × 1015M⊙ in a 100 × 45 Mpc supercluster region in the plane of the sky (0.030 < z < 0.041). In addition, our sample includes eight clusters from the immediate neighborhoods of the superclusters and ten field clusters at the same z. The derived properties of the…

Peculiar motions of galaxy clusters and groups in the Hercules and Leo supercluster regions

We present the results of our study of the peculiar motions for 41 galaxy clusters and groups in the regions of the Hercules and Leo superclusters (0.027 < z < 0.045). For this purpose, based on SDSS

Dwarf-to-giant galaxy ratio in superclusters and in the field at 0.02 < z < 0.05

We report the results of the study of red-sequence (RS) galaxies in 47 galaxy clusters (0.023 < z < 0.047) located in different environments: in the superclusters Hercules and Leo, and in the field,

Evolution of galaxy groups

We study the variations of the properties of groups of galaxies with dynamical masses of 1013M⊙ 0.027, and is located in the regions of the following superclusters of galaxies: Hercules, Leo, Bootes,

Properties of 34 massive galaxy groups within 0.012 < z < 0.027

In order to extend the relationship between the infrared luminosity of groups and clusters of galaxies and their dynamic mass to the 1–5 × 1013M⊙ mass region, we selected from the study of Ramella et

Galaxy Clusters and Their Outskirts: the “Red Sequence”, Star Formation Rate, Stellar Mass

We study the nearest outskirts (R < 3R200c) of 40 groups and clusters of galaxies of the local Universe (0.02 < z < 0.045 and 300 km s-1 < σ < 950 km s-1). Using the SDSS DR10 catalog data, we

Structure of galaxy groups and clusters and measurement of their masses

We report the results of measurement and comparison of masses for a sample of 29 groups and clusters of galaxies (z < 0.1). We use the SDSSDR7 archive data to determine dynamical masses from the

Outskirts of Galaxy Clusters A1139, A1314, A1656, A2040, A 2052, A2107: Star-Formation Rate

We investigate the variation of the fraction of galaxies with suppressed star formation (MK < −21.m5) and early-type galaxies (fracE) of the “red sequence” along the projected radius in six galaxy

Pre-main-sequence stars older than 8 Myr in the Eagle nebula

Attention is given to a population of 110 stars in the NGC 6611 cluster of the Eagle nebula that have prominent near-infrared excess and optical colours typical of pre-main-sequence (PMS) stars older

Constraints on large-scale magnetic fields in the intergalactic medium using cross-correlation methods

Large-scale coherent magnetic fields in the intergalactic medium are presumed to play a key role in the formation and evolution of the cosmic web, and in large scale feedback mechanisms. However,

Quantifying the rarity of the local super-volume

We investigate the extent to which the number of clusters of mass exceeding $10^{15}\, M_{\odot }\, h^{-1}$ within the local super-volume ($\lt 135\mathrm{\, Mpc\, }h^{-1}$) is compatible with the

Mass Profile of the Infall Region of the Abell 2199 Supercluster

Using a redshift survey of 1323 galaxies (1092 new or remeasured) in a region of 95 deg2 centered on the nearby galaxy cluster Abell 2199, we analyze the supercluster containing A2199, A2197, and an

We present a morphological study of the two richest superclusters from the 2dFGRS (SCl 126, the Sloan Great Wall, and SCl 9, the Sculptor supercluster). We use Minkowski functionals, shapefinders,

Kinematics of the Hercules Supercluster

The Hercules supercluster consists of the Abell clusters A2147, A2151, and A2152. Previous studies of the kinematics have been confounded by the difficulty of correctly assigning galaxies to the
