We apply a friends-of-friends algorithm to the combined Updated Zwicky Catalog (UZC, Cat. )and Southern Sky Redshift Survey (SSRS2, Cat. ) to construct a catalog of 1168 groups...

We report 60 new radial velocities, as well as new photographic and CCD photometry. Cone search capability for table J/AJ/105/788/table1 (Photometric & Spectroscopic data)

New results are presented of Arecibo observations in the 21 cm line of 765 galaxies with declinations between 15.5 deg and 21.5 deg, in the Pisces-Perseus supercluster zone. If...

Measurements of 544 radial velocities, 229 optical and 315 in the 21cm HI line, are presented for galaxies, mostly in the declination strip +33.5 deg<Dec<+39.5deg in the...

As part of a program to study the kinematics of cD clusters of galaxies, we have measured the radial velocities of 75 galaxies in the field of Abell 2107. Sixty-eight of these...

(no description available) Cone search capability for table J/A+AS/106/1/table4 (Radio sources in the clusters fields) Cone search capability for table J/A+AS/106/1/table5...

The use of galaxy clusters as cosmological probes relies on a detailed understanding of their properties. They define cluster selection and ranking, which is linked to a...

We analysed the clustering of a photometric sample of galaxy clusters selected from the Third Data Release of the Kilo-Degree Survey, focusing on the redshift-space two-point...

We are investigating the star formation in galaxies of the actively evolving Dorado group where, for a large fraction of both early- and late-type galaxies, signatures of...

We investigate the relations between nuclear star clusters (NSCs) and their host galaxies, as well as conduct a comparison between the structural properties of nucleated and...

Brightest cluster galaxies (BCGs) have grown by accreting numerous smaller galaxies and can be used as tracers of cluster formation and evolution in the cosmic web. However,...

Thermal gas in the center of galaxy clusters can show substantial motions that generate surface brightness and temperature discontinuities known as cold fronts. The motions may...

Ophiuchus is one of the most massive clusters known, but due to its low Galactic latitude its optical properties remain poorly known. We investigate the optical properties of...

Leo T is the lowest mass gas-rich galaxy currently known and studies of its gas content help us understand how such marginal galaxies survive and form stars. We present deep...

We report observations of the radio galaxy 3C317 (at z=0.0345) located at the center of the Abell cluster A2052, obtained with the VLT/MUSE integral field spectrograph. The...

A fraction of galaxy clusters host diffuse radio sources whose origins are investigated through multi-wavelength studies of cluster samples. We investigate the presence of...

We analyze the globular cluster (GC) systems in two very different galaxies, NGC 3115 and NGC 1399. With the papers of this series, we aim at highlighting common and different...

At low redshift, early-type galaxies often exhibit a rising flux with decreasing wavelength in the 1000-2500{AA} range, called "UV upturn". The origin of this phenomenon is...

Neutral hydrogen represents the major observable baryonic constituent of galaxies that fuels the formation of stars through transformation of molecular hydrogen. The emission of...

We cross-correlate the Planck Catalogue of Compact Sources (PCCS) with the fully sampled 84deg^2^ Herschel Virgo Cluster Survey (HeViCS) fields. We search for and identify the...
