We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg^2^ of imaging data from the Kilo Degree Survey (KiDS). For a flat...

We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational...

The increasingly neutral intergalactic gas at z>6 impacts the Lyman-{alpha} (Ly{alpha}) flux observed from galaxies. One luminous galaxy, COLA1, stands out because of its...

We present new VLT/MUSE observations of the Hubble Frontier Field (HFF) galaxy cluster MACS J1149.5+2223, lensing the well-known supernova "Refsdal" into multiple images, which...

We quantify the stellar rotation of galaxies by computing the {lambda}R parameter, a proxy for the stellar angular momentum in a sample of 106 intermediate-redshift galaxies...

We present the First Cosmic Gamma-ray Horizon (1CGH) catalogue, featuring gamma-ray detections above 10GeV based on 16 years of observations with the Fermi Large Area Telescope...

This work is part of ongoing efforts to detect fast radio bursts using the Murchison Widefield Array (MWA) in a spectral window below 300MHz. We used an image-based method based...

The high-ionization mid-IR lines, excited in the narrow-line regions of active galactic nuclei (AGN), barely affected by stellar excitation and dust extinction, trace the AGN...

This paper presents a search for high redshift galaxies from the Euclid Early Release Observations program `Magnifying Lens.' The 1.5deg2 area covered by the twin Abell lensing...

The Euclid Early Release Observations (ERO) programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7deg^2^,...

The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of ~5700deg^2^. The high angular resolution of LOFAR with...

This catalog contains the third major update of new optical and radio data for the strong sources in the Revised Third Cambridge Catalogue (3CR). Positions, redshifts,...

We present volume-limited samples of cataclysmic variables (CVs) and AM CVn binaries jointly selected from SRG/eROSITA eRASS1 and Gaia DR3 using an X-ray + optical color-color...

Galactic X-ray sources are diverse, ranging from active M dwarfs to compact object binaries, and everything in between. The X-ray landscape of today is rich, with point source...

Our knowledge of Giga-electron volt (GeV) radio galaxies has been revolutionized by the Fermi-LAT Telescope, which provides an excellent opportunity to study the physical...

A two-component model of radio emission has been used to explain some radio observational properties of Active Galactic Nuclei (AGNs) and, in particular, of blazars. In this...

The field of computer vision has greatly matured in the past decade, and many of the methods and techniques can be useful for astronomical applications. One example is in...

This paper presents the identification of galaxy clusters from the photometric redshift catalog based on three imaging surveys of SCUSS, Sloan Digital Sky Survey, and unWISE. By...

We present deep, wide-field, Ks-band (2.14-micron) images towards 87 southern massive star formation regions traced by methanol maser emission. Using point-spread function...

We present a catalogue of the 322 damped Lyman alpha absorbers taken from the literature. All damped Lyman alpha absorbers are included, with no selection on redshift or quasar...
