Stellar properties of Sun-like stars SDST III
The Survey for Distant Solar Twins aims to find stars very similar to the Sun at distances of 1-4kpc, several times more distant than any currently known solar twins and... -
Omega/WINGS clusters/fields galaxies
The observed properties of galaxies are strongly dependent on both their total stellar mass and their morphology. Furthermore, the environment is known to play a strong role in... -
HSC gLSB galaxies structures and SB properties
Rare giant low surface brightness galaxies (gLSBGs) act as a stress test for the current galaxy formation paradigm. To answer the question 'How rare are they?', we estimate... -
n-catpure abundances in NGC 6752
Globular clusters have been widely studied in terms of light element variations present in their different stellar populations. However, the nature of the polluter(s)... -
Remnant merger structures of ETGs with SDSS
We search for signatures of recent galaxy close interactions and mergers in a sample of 202 early-type galaxies in the local universe from the public SDSS Stripe82 deep images... -
X-ray catalog and classification of 4FGL-DR4 UGSs
Our survey of the fourth Fermi Large Area Telescope catalog (4FGL) unassociated gamma-ray source regions using the X-Ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT)... -
NESSI: resolving wide binaries in Gaia & SUPERWIDE
Stellar systems consisting of three or more stars are not an uncommon occurrence in the Galaxy. Nearly 50% of solar-type wide binaries with separations >1000AU are actually... -
MGQPC photo-z and high-probability pair catalogs
The identification of physically associated kiloparsec-scale quasar pairs is important for understanding galaxy evolution, the growth of supermassive black holes, and the... -
CEERS Key Paper. VIII. NIRSpec & NIRCam sp.
We use James Webb Space Telescope Near-Infrared Camera Wide Field Slitless Spectroscopy (NIRCam WFSS) and the Near-Infrared spectrograph (NIRSpec) in the Cosmic Evolution Early... -
3D kinematics in the ONC. II. Mass-dependent results
We present the kinematic analysis of 246 stars within 4' from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formation across the... -
QSOs at z~4 from Subaru/HSC wide field & BH masses
We investigate the black hole mass function (BHMF) and Eddington-ratio distribution function (ERDF) of broad-line active galactic nuclei (AGNs) at z=4, based on a sample of 52... -
Classifying intermediate-z galaxies in SDSS
We select a sample of 1437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey galaxy properties from the Portsmouth group by detection of the... -
ACO 746 analysis with Subaru & MMT spectra data
The galaxy cluster A746 (z=0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intricate... -
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... -
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...
