We present a detailed study of the stellar kinematic properties of red member galaxies in the cores of four strong lensing galaxy clusters at intermediate redshifts included in...

Of the eROSITA/eFEDS sources (Brunner et al., 2022A&A...661A...1B, Cat. J/A+A/661/A1, Paper I), 24774 of 27369 have reliable counterparts (90.5%) in the main sample and 231...

The Perseus cluster is a nearby cool-core galaxy cluster that hosts an archetypal radio mini-halo. Recent Low Frequency Array (LOFAR) High Band Antenna (HBA) observations at...

We present the design and observations of low-resolution JWST/NIRSpec PRISM spectroscopy from the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization...

Taking advantage of ~4700 deg^2^ optical coverage of the Southern sky offered by the VST ATLAS survey, we construct a new catalogue of photometrically selected galaxy groups and...

We study the global kinematics of the Perseus galaxy cluster (A426) at redshift z=0.017 using a large sample of galaxies from our new MMT/Hectospec spectroscopic observation for...

In 2022 November, the James Webb Space Telescope (JWST) returned deep near-infrared images of A2744-a powerful lensing cluster capable of magnifying distant, incipient galaxies...

The radio jets of radio galaxies in galaxy clusters are often bent due to the ram pressure of the intracluster medium. Most studies of bent radio tails initially identified...

We study the physical properties of weak-lensing subhalos in the Coma cluster of galaxies using data from galaxy redshift surveys. The data include 12,989 galaxies with measured...

Over the years, several compact group catalogues have been constructed using different methods, but most of them are not deep enough to go beyond the very local universe with a...

We present the clump populations detected in 18 lensed galaxies at redshifts 1-- 8.5 within the lensing cluster field SMACS0723. The recent JWST Early Release Observations of...

We present a catalogue of 4499 groups and clusters of galaxies from the first data release of the multi-filter (5 broad, 7 narrow) Southern Photometric Local Universe Survey...

Observational extragalactic catalogs over wide sky areas are essential for uncovering the large-scale structure of the Universe. They allow, among others, cosmological studies...

Several studies have reported a nearly linear correlation between the molecular gas and star formation rate surface density, the so-called Kennicutt-Schmidt (KS) law. We aim to...

We examine the H I gas kinematics of galaxy pairs in two clusters and a group using Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pilot survey observations. We...

Using the Five-hundred-meter Aperture Spherical radio Telescope, we have performed an Ursa Major supergroup HI survey covering the entire UMa region centered at...

We present 21-cm observations of a 10x2deg^2^ region in the Virgo cluster, obtained as part of the Arecibo Galaxy Environment Survey. 289 sources are detected over the full...

We present the multiwavelength photometry of two Frontier Fields massive galaxy clusters, MACS-J0717 and MACS-J1149, and their parallel fields, ranging from Hubble Space...

We present an analysis of the X-ray active galactic nucleus (AGN) population in a sample of seven massive galaxy clusters in the redshift range 0.35<z<0.45. We utilize...

The Spitzer Reionization Lensing Cluster Survey (SRELICS, PI: Bradac) is the Spitzer counterpart to the RELICS HST Treasury program (PI: Coe) to survey 41 massive galaxy clusters.
