Photometric parameters for 98 early-type galaxies in the central for 11 clusters, belonging to the Ursa Major supercluster, are presented. Galaxies in the following clusters...

A catalogue of 1192 galaxies in the central regions (30' x 30') of 11 clusters in the Ursa Major supercluster is presented. For each galaxy equatorial and relative coordinates...

Detailed identification of radio sources within the Abell radii in 26 rich galactic clusters of the FIRST catalog with optical objects of the APM and DSS surveys had been...

We present free-form gravitational lensing models derived with the WSLAP+ code for the six Hubble Frontier Fields clusters using the latest data available from the Frontier...

We quantify the star formation (SF) in the inner cores (R/R_200_~<0.3) of 24 massive galaxy clusters at 0.2~<z~<0.9 observed by the Herschel Lensing Survey and the...

We present an updated strong-lensing analysis of the massive cluster Abell 370 (A370), continuing the work first presented in L17. In this new analysis, we take advantage of the...

The well-known cluster of galaxies ZwCl0024+1652 at z~0.4 lacks an in-depth morphological classification of its central region. While previous studies provide a visual...

We propose a new soft clustering scheme for classifying galaxies in different activity classes using simultaneously four emission-line ratios: log([NII]/H{alpha}),...

We study a sample of 207 nearby galaxy groups and clusters observed with XMM-Newton. Key aspects of this sample include the large size, the high data quality, and the large...

We present the results of a search for galaxy clusters and groups in the ~2deg^2^ of the COSMOS field using all available X-ray observations from the XMM-Newton and Chandra...

This paper is the second in a series presenting the results of our deep H{alpha}-line survey towards protoclusters at z>2, based on narrow-band imaging with the Subaru...

We identify a sample of 1959 massive clusters of galaxies in the redshift range of 0.7<z<1.0 from the survey data of Sloan Digital Sky Survey (SDSS) and Wide-field...

We have mapped the structure and connectivity of the Shapley supercluster core and its surroundings as traced by its member galaxies. To achieve this, we have carried out a new...

We present an analysis of the relatively low mass (~2400M_{sun}_), ~800Myr, Galactic open cluster, NGC 2818, using Gaia DR2 results combined with VLT/FLAMES spectroscopy. Using...

We present the study of the dynamical status of the galaxy cluster CL1821+643, a rare and intriguing cool-core cluster hosting a giant radio halo. We base our analysis on new...

The observed delay-time distribution (DTD) of Type-Ia supernovae (SNe Ia) is a valuable probe of SN Ia progenitors and physics, and of the role of SNe Ia in cosmic metal...

We used optical imaging and spectroscopic data to derive substructure estimates for local Universe (z<0.11) galaxy clusters from two different samples. The first was selected...

We present a sample of 329 low-to intermediate-redshift (0.05<z<0.3) brightest cluster galaxies (BCGs) in X-ray-selected clusters from the SPectroscopic IDentification of...

The Coma supercluster (100h^-1^Mpc) offers an unprecedented contiguous range of environments in the nearby Universe. In this paper, we present a catalogue of spectroscopically...

We present an extensive compendium of photometrically determined structural properties for all Calar Alto Legacy Integral Field spectroscopy Area (CALIFA)galaxies in the third...
