Dwarf galaxies are excellent cosmological probes, because their shallow potential wells make them very sensitive to the key processes that drive galaxy evolution, including...

We study the bar pattern speeds and corotation radii of 225 barred galaxies, using integral field unit data from MaNGA and the Tremaine-Weinberg method. Our sample, which is...

We present the Extragalactic Serendipitous Swift Survey (ExSeSS), providing a new well-defined sample constructed from the observations performed using the Swift X-ray...

We combine photometric metallicities with astrometry from Gaia DR3 to examine the chemodynamic structure of ~250000 K dwarfs in the solar neighbourhood (SN). In kinematics, we...

Galaxy morphology in atomic hydrogen (H I) and in the ultraviolet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H I disc...

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...

We present a homogeneous analysis of all DA stars labelled as magnetic in the Montreal White Dwarf Database. Our sample is restricted to almost all known magnetic white dwarf...

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...

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...

This service exposes photometric light curves of eclipsing binaries from Gaia DR3 epoch photometry via the VO SSA protocol. The light curves are published per-band and are also...

We present the Heraklion Extragalactic Catalogue, or HECATE, an all-sky value-added galaxy catalogue, aiming to facilitate present and future multiwavelength and multimessenger...

Adding to the large radial velocity survey of nearby solar-type stars (summary in Tokovinin, 2023a), spectroscopic orbits are determined for four hierarchical systems: HIP 49442...

In the era of a data-driven landscape, the development of an efficient and interpretable method has become a pivotal tool for robustly identifying memberships of clusters. We...

This is gaia_source from the Gaia Data Release 3, stripped to just enough columns to enable basic science (but therefore a bit faster and simpler to deal with than the full...

This schema contains data re-published from the official Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to support combining its data with local tables (the...

The Atacama Large Millimetre/submillimetre Array (ALMA) is the world's most advanced radio interferometric facility, producing science data with an average rate of about 1 TB...

Two recent papers (Ghez et al. 2008ApJ...689.1044G; Gillessen et al. 2009ApJ...692.1075G) have estimated the mass of and the distance to the massive black hole (MBH) in the...

The International Celestial Reference System (ICRS) is realized in the radio band by a catalog of radio source positions obtained by very long baseline interferometry (VLBI)...

Open clusters are vital laboratories for studying stellar dynamics and evolution, with mass segregation-the preferential concentration of massive stars toward cluster...

AST3-2 is the second of the three Antarctic Survey Telescopes, aimed at wide-field time-domain optical astronomy. It is located at Dome A, Antarctica, which is by many measures...
