Telescopes don't make catalogues! [PDF]

, 2010
Astronomical instruments make intensity measurements; any precise astronomical experiment ought to involve modeling those measurements. People make catalogues, but because a catalogue requires hard decisions about calibration and detection, no catalogue can contain all of the information in the raw pixels relevant to most scientific investigations ...

Applying Machine Learning to Catalogue Matching in Astrophysics [PDF]

Mon.Not.Roy.Astron.Soc.360:69-75,2005, 2005
We present the results of applying automated machine learning techniques to the problem of matching different object catalogues in astrophysics. In this study we take two partially matched catalogues where one of the two catalogues has a large positional uncertainty. The two catalogues we used here were taken from the HI Parkes All Sky Survey (HIPASS),

Proper identification of RR Lyrae Stars brighter than 12.5 mag [PDF]

, 2005
RR Lyrae stars are of great importance for investigations of Galactic structure. However, a complete compendium of all RR-Lyraes in the solar neighbourhood with accurate classifications and coordinates does not exist to this day. Here we present a catalogue of 561 local RR-Lyrae stars V_max less equal 12.5 mag according to the magnitudes given in the ...

A revised catalogue of 294 Galactic supernova remnants [PDF]

JApA, 40, 36 (2019), 2019
A revised catalogue of Galactic supernova remnants (SNRs) is presented, along with some simple statistics of their properties. Six new SNRs have been added to the catalogue since the previous published version from 2014, and six entries have been removed, as they have been identified as HII regions, leaving the number of entries in the catalogue at 294.

A sharper view of the outer Galaxy at 1420 and 408 MHz from the Canadian Galactic Plane Survey II: The catalogue of extended radio sources [PDF]

Mon.Not.Roy.Astron.Soc.379:289-296,2007, 2007
A new catalogue of extended radio sources has been prepared based on arcminute-resolution 1420 MHz images from the Canadian Galactic Plane Survey (CGPS). The new catalogue provides both 1420 MHz and 408 MHz flux density measurements on sources found near the Galactic plane in the second quadrant of our Galaxy. In addition cross-identifications are made

Gaia Data Release 3. Catalogue validation [PDF]

Astronomy & Astrophysics, 2022
The third gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly two billion sources.

Improving the open cluster census. II. An all-sky cluster catalogue with Gaia DR3 [PDF]

Astronomy & Astrophysics, 2023
Data from the Gaia satellite are revolutionising our understanding of the Milky Way. With every new data release, there is a need to update the census of open clusters. We aim to conduct a blind, all-sky search for open clusters using 729 million sources

A catalogue of white dwarfs in Gaia EDR3 [PDF]

Monthly notices of the Royal Astronomical Society, 2021
We present a catalogue of white dwarf candidates selected from Gaia early data release three (EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia quality flags to remove objects with unreliable measurements while ...
