Wide-sep. lensed QSOs + dual-QSO cand. from CatNorth
Wide-separation lensed quasars (WSLQs) represent a special but rare subclass of strongly lensed quasars with multiple images, magnified by massive galaxy cluster lenses, which... -
159897 APOGEE Abundances from spectra with SNR<150
Large spectroscopic surveys rely on automated pipelines to deliver homogeneous stellar labels; however, a substantial fraction of observations are carried out at a low... -
AGN 8GHz measurements
Very long baseline interferometry (VLBI) measurements of the sizes of compact extragalactic radio sources, jetted active galactic nuclei, provide data for probing the angular... -
VST ATLAS QSO survey I photometric study
We present the VST ATLAS Quasar Survey, consisting of ~1229000 quasar (QSO) candidates with 16 < g < 22.5 over ~4700 deg^2^. The catalogue is based on VST ATLAS+NEOWISE... -
NS in binary systems kick velocities study
Understanding the natal kicks received by neutron stars (NSs) during formation is a critical component of modelling the evolution of massive binaries. Natal kicks are an... -
Coma Cluster DESI galaxies
We investigate the kinematic properties of the Coma galaxy cluster using a new, large, spectroscopic sample of member galaxies, from the Dark Energy Spectroscopic Instrument... -
JWST Bullet Cluster redshifts and spectra
The Bullet Cluster (1E 0657-56), located at a redshift of 0.296, is among the best-known merging galaxy clusters and a key laboratory for dark matter studies. Although the mass... -
HECATE nearby galaxies stellar properties
We present the Heraklion Extragalactic Catalogue, or HECATE, an all-sky value-added galaxy catalogue, aiming to facilitate present and future multiwavelength and multimessenger... -
large-scale 3D extinction mapping
Three-dimensional extinction mapping of the Milky Way faces a fundamental trade-off: Gaia's precise astrometry and photometry enable high-resolution mapping but only to limited... -
Stellar mass and morphology in the cosmic web
In this work, we investigate if the location of galaxies within the large-scale structures (LSS) of the Universe leaves an imprint in their stellar mass (M) and morphology. To... -
FRIs and FRIIs in LoTSS DR2 with galaxy clusters
The origin of the morphological dichotomy between Fanaroff-Riley Class I (FRI) and Class II (FRII) radio galaxies has long been debated. In this study, we investigate whether... -
OB associations from LAMOST DR7 & Gaia DR3
OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution,... -
Radio-loudness stat. of QSOs from Quaia-VLASS
Quasars are objects of high interest in extragalactic astrophysics, cosmology, and astrometry. One of their useful qualities is their potential radio-loudness. However, the... -
All-sky cat. of molecular clouds from 3D dust map
Understanding the distribution and properties of molecular clouds is crucial for tracing the structure and evolution of the interstellar medium (ISM) and the large-scale... -
Extinction catalog from Gaia DR3 & LAMOST DR11
We present a comprehensive 3D dust-reddening map covering the entire Milky Way, constructed by combining reddening estimates based on Large Sky Area Multi-Object Fiber... -
New redshifts for SDSS galaxies from visual inspection
This work presents a catalog of reidentified redshifts of 853 galaxies for which the redshifts of overlapping foreground objects were registered in the Sloan Digital Sky Survey... -
Optical polarization variability of 15 blazars
Optical polarization can be an important probe of particle acceleration and high-energy emission processes in relativistic jets from supermassive black holes. Here, we combine... -
HE 1237-2252 spectra
Extreme sudden changes in the flow of accreting gas onto supermassive black holes manifest themselves via large-amplitude multiband continuum variability, as well as changes to... -
Galaxy clusters in the LoTSS-DR3
The third data release (DR3) of the LOFAR Two-metre Sky Survey (LoTSS) provides an unprecedented view of the northern sky at 144MHz, comprising more than 13 million radio... -
NGC 7213 ATCA 5.5 and 9GHz and Swift/XRT obs.
Low-luminosity active galactic nuclei (LLAGNs) often host weak radio jets whose propagation and impact on their host galaxies are strongly influenced by the surrounding...
