Title:: Apertif Time Domain FRB detection cone search (DR2)
Short Name:: Detected FRB
Date:: 31 Jul 2024 11:50:27
Publisher:: ASTRON
Description:: This is the final, full data release from the Apertif Radio Transient System (ARTS), a supercomputing radio-telescope instrument that performed real-time FRB detection and localisation on the Westerbork Synthesis Radio Telescope (WSRT) interferometer. It reached coherent-addition sensitivity over the entire field of the view of the primary- dish beam. The Apertif FRB survey (ALERT) detected 24 new FRBs, and interferometrically localised each of these to 0.4−10 sq. arcmin. All detections are broad band and very narrow, of order 1 ms duration, with high dispersion measures. Please note that the ARTS DR2 collection includes all data from the DR1 collection.

Title:: Apertif Time Domain FRB detection cone search (DR1)
Short Name:: Detected FRB
Date:: 31 Jul 2024 11:50:09
Publisher:: ASTRON
Description:: This is the first release of data from the Apertif Radio Transient System (ARTS), a supercomputing radio-telescope instrument that performs real-time FRB detection and localisation on the Westerbork Synthesis Radio Telescope (WSRT) interferometer. It reaches coherent-addition sensitivity over the entire field of the view of the primary- dish beam. After commissioning results verified the system performed as planned, we initiated the Apertif FRB survey (ALERT). Over the first 5 weeks we observed at design sensitivity in 2019, we detected 5 new FRBs, and interferometrically localised each of these to 0.4−10 sq. arcmin. All detections are broad band and very narrow, of order 1 ms duration, and unscattered. Dispersion measures are generally high. Please note that the ARTS DR1 collection available from this end-point is superseded by the ARTS DR2 collection. DR2 includes all data from the DR1 collection that can be queried here.

Title:: Parameters of 220 million stars from Gaia BP/RP (XP) spectra
Short Name:: XP ap-pars
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
Description:: We present astrophysical parameters of 220 million stars, based on Gaia XP spectra and near-infrared photometry from 2MASS and WISE. Instead of using ab initio stellar models, we develop a data-driven model of Gaia XP spectra as a function of the stellar parameters, with a few straightforward built-in physical assumptions. This resource is a VO re-publication of the resulting catalog of stellar parameters. For bulk downloads, the covariances, the trained model, and more, see https://zenodo.org/record/7811871.

Title:: The Fifth Catalogue of Nearby Stars (CNS5)
Short Name:: CNS5
Date:: 27 Dec 2024 08:31:04
Publisher:: The GAVO DC team
Description:: The Fifth Catalogue of Nearby Stars (CNS5) aims to provide the most volume-complete sample of stars in the solar neighbourhood. The CNS5 is compiled based on trigonometric parallaxes from Gaia EDR3 and Hipparcos, and supplemented with astrometric data from Spitzer and ground-based surveys carried out in the infrared. The CNS5 catalogue is statistically complete down to 19.7 mag in G-band and 11.8 mag in W1-band absolute magnitudes, corresponding to a spectral type of L8. Continuous updates of observational data for nearby stars from all sources were collected and evaluated. For all known stars in the 25 pc sphere around the Sun, the best values of positions in space, velocities, and magnitudes in different filters are presented.
