Abell Clusters
The ABELL database contains information from a catalog of clusters of galaxies, each having at least 30 members within the magnitude range m3 to m3+2 (m3 is the magnitude of the... -
HEAO 1 A2 Piccinotti Catalog
The HEAO 1 A-2 experiment's operations began on day 224 of 1977 (12 August 1977) and ended on day 739 of 1977 (9 January 1979). The A-2 experiment performed two independent,... -
Archive of AGN spectral observations
The archive of AGN spectral observations is obtained on AZT-8 telescope at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. It represents the result of... -
SRG/eROSITA zsp of 216 galaxy clusters
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The... -
MeerKAT Absorption Line Survey (MALS). I. DR1
The MeerKAT Absorption Line Survey (MALS) has observed 391 telescope pointings at the L band (900-1670MHz) at {delta}<~+20{deg}. We present radio continuum images and a... -
Gaia EDR3 trailing & leading tidal tail of M2
Using photometry and proper motions from Gaia Early Data Release 3, we detect a 45{deg} long trailing stellar debris stream associated with the old, metal- poor globular cluster... -
Xray obs. of gal. hosting nuclear star clusters
We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense... -
Ages, masses & kinematics of GALAH MS turnoff stars
Main-sequence turnoff (MSTO) stars are good tracers of Galactic populations since their ages can be reliably estimated from atmospheric parameters. Based on the GALAH survey, we... -
Galaxies bulge & disk data from SHARDS & HST
We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we modeled the surface... -
Distances to Local Group galaxies. II. Fornax dSph
We determine three independent Population II distance moduli to the Fornax dwarf spheroidal (dSph) galaxy, using wide-field, ground-based VI imaging acquired with the... -
MALS SALT-NOT survey of MIR-selected AGN at z<3.5
We present results of an optical spectroscopic survey using SALT and the Nordic Optical Telescope to build a Wide-field Infrared Survey Explorer mid-infrared color-based,... -
EXPRES radial volocity for {tau} Ceti
To accurately characterize the planets a star may be hosting, stellar parameters must first be well determined. {tau}Ceti is a nearby solar analog and often a target for... -
SFACT. III. SFF01 -10 and -15 spectral data
The Star Formation Across Cosmic Time (SFACT) survey is a new narrowband survey designed to detect emission-line galaxies (ELGs) and quasi-stellar objects (QSOs) over a wide... -
SFACT. II. SFF01 -10 and -15 emission line objects
Star Formation Across Cosmic Time (SFACT) is a new narrowband (NB) survey designed to detect faint emission-line galaxies (ELGs) and QSOs over a broad range of redshifts. Here... -
Mrk 421 multiwavelength light curves
We have performed the first broadband study of Mrk 421 from radio to TeV gamma rays with simultaneous measurements of the X-ray polarization from IXPE. The data were collected... -
DESI Peculiar Velocity survey
We describe the target selection and characteristics of the DESI Peculiar Velocity Survey, the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP)... -
Core-collapses supernovae host galaxies
We present a comprehensive study of an unbiased sample of 150 nearby (median redshift, z = 0.014) core-collapse supernova (CCSN) host galaxies drawn from the All-Sky Automated... -
Stellar companions of exoplanet host stars
Stellar multiplicity is a key aspect of exoplanet diversity, as the presence of more than one star in a planetary system can have both devastating and positive effects on its... -
Quiescent galaxies from SHELS and SDSS
We use surveys covering the redshift range 0.05<z<3.8 to explore quiescent galaxy scaling relations and the redshift evolution of the velocity dispersion, size, and... -
Opt. morphologies of FIR & submm host gal. in COSMOS
We present a host morphological study of 1266 far-infrared galaxies (FIRGs) and submillimeter galaxies (SMGs) in the Cosmic Evolution Survey field using the F160W and F814W...
