BAX X-Ray Galaxy Clusters and Groups Catalog
This table contains the BAX X-Ray Galaxy Clusters and Groups Catalog. BAX (`Base de Donnees Amas de Galaxies X': see <a... -
Bochum Galactic Disk Survey (BGDS) DR2 light curves
This service exposes the light curves of stars produced by the Bochum Galactic Disk Survey DR2; several million light curves are provided in the SDSS i and r bands. The... -
BGDS DR2 Matched Photometry Cone Search
Median photometry in U, B, V, z, r, and i broadbands as well as the narrow bands OIII, NB, Halpha and SII for particular objects; all measurements have... -
BGDS DR2 Median Photometry Cone Search
Extracted sources from the Bochum Galactic Disk Survey. We provide median photometry in U, B, V, z, r, and i broadbands as well as the narrow bands OIII,... -
AllWISE Catalog of Mid-IR AGNs
This table contains an all-sky sample of ~1.4 million active galactic nuclei (AGNs) meeting a two-color infrared photometric selection criterion for AGNs as applied to sources... -
Abell Clusters Measured Redshifts Catalog
The all-sky ACO (Abell, Corwin and Olowin 1989, ApJS, 70, 1) Catalog of 4073 rich clusters of galaxies and 1175 southern poor or distant S-clusters has been searched for... -
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,... -
MATLAS ultra diffuse galaxies
Recent advances in deep dedicated imaging surveys over the past decade have uncovered a surprisingly large number of extremely faint low surface brightness galaxies with large... -
A GCs search in M31 with Gaia, PS1, LAMOST, PAndAS
We have found 50 new globular cluster (GC) candidates around M31 with Gaia Early Data Release 3 (EDR3), with the help of Pan-STARRS1 DR1 magnitudes and Pan-Andromeda... -
Bright gamma-ray blazars among the 4LAC
Gamma-ray flares of blazars may be accompanied by high-energy neutrinos due to interactions of high-energy cosmic rays in the jet with photons, as suggested by the detection of... -
WISDOM Proj XII ALMA CO(2-1) of clumps and clouds
We present a study of molecular structures (clumps and clouds) in the dwarf galaxy NGC 404 using high-resolution (~0.86 * 0.51 pc^2^) Atacama Large Millimeter/sub-millimeter... -
Stellar properties of Sun-like stars from SDST II
Studies of solar twins have key impacts on the astronomical community, but only ~100-200 nearby solar twins (<1 kpc) have been reliably identified over the last few decades.... -
RVs of O-type stars in BLOeM survey
The interpretation of observations of gravitational waves, transients, and distant galaxies in the high-redshift Universe heavily relies on our understanding of massive stars at... -
Star ages with ML and GALAH DR3 spectra
We present the first large-scale study that demonstrates how ages can be determined for large samples of stars through Galactic chemical evolution. Previous studies found that... -
~1000 RC sources in M33 with the VLA
Studying the interplay between massive star formation and the interstellar medium (ISM) is paramount to understand the evolution of galaxies. Radio continuum (RC) emission... -
Unobscured QSO cand. in the southern sky with KS4
We present a catalog of unobscured quasi-stellar object (QSO) candidates in the Southern Hemisphere from the early interim data of the KMTNet Synoptic Survey of Southern Sky... -
Comprehensive radio study of NLS1s
Narrow-line Seyfert 1 (NLS1) galaxies are a type of active galactic nuclei (AGN) that were originally classified as sources with little to no radio emission. Although the class... -
Euclid obs. of extragalactic star clusters
We examine the star cluster populations in the three nearby (3.20-3.45Mpc) galaxies IC 342, NGC 2403, and Holmberg II, observed as part of the Euclid Early Release Observations... -
Binary clusters in the Galactic disk
Binary clusters (BCs) provide valuable observational constraints on the formation, early evolution, and dynamical interactions of star clusters. Their spatial and kinematic...
