Abstract:
Accurately accounting for the AGN phase in galaxy evolution requires a
large, clean AGN sample. This is now possible with
SRG/eROSITA, which completed its first all-sky X-ray survey (eRASS1)
on June 12, 2020. The public Data Release 1 (DR1, Jan 31, 2024)
includes 930,203 sources from the Western Galactic Hemisphere.
The data enable the selection of a large AGN sample and the discovery
of rare sources. However, scientific return depends on accurate
characterisation of the X-ray emitters, requiring high-quality
multiwavelength data. This paper presents the identification and
classification of optical and infrared counterparts to eRASS1 sources.
Counterparts to eRASS1 X-ray point sources were identified using Gaia
DR3, CatWISE2020, and Legacy Survey DR10 (LS10) with the Bayesian NWAY
algorithm and trained priors. Sources were classified as Galactic or
extragalactic via a Machine Learning model combining optical/IR and
X-ray properties, trained on a reference sample. For extragalactic
LS10 sources, photometric redshifts were computed using Circlez.
Within the LS10 footprint, all 656,614 eROSITA/DR1 sources have at
least one possible optical counterpart; ∼570,000 are extragalactic and
likely AGN. Half are new detections compared to AllWISE, Gaia, and
Quaia AGN catalogues. Gaia and CatWISE2020 counterparts are less
reliable, due to the survey's shallowness and the limited amount of
features available to assess the probability of being an X-ray
emitter. In the Galactic Plane, where the overdensity of stellar
sources also increases the chance of associations, using conservative
reliability cuts, we identify approximately 18000 Gaia and 55000
CatWISE2020 extragalactic sources.
We release three high-quality counterpart catalogues - plus the
training and validation sets - as a benchmark for the field. These
datasets have many applications, but in particular empower researchers
to build AGN samples tailored for completeness and purity,
accelerating the hunt for the Universe's most energetic engines.
Description:
In this paper, we describe the construction of the three catalogues
listing the most reliable counterparts to the point sources
detected by eROSITA (PSF Half Energy Width of ∼30" and corresponding
1σ median positional uncertainty of ∼4.5" and a uniform flux
limit at 50% completeness of F0.5-2keV>5x10-14erg/s/cm2) in the
first all-sky pass over the Western hemisphere (eROSITA_DE), using
LS10, Gaia DR3, and CW2020, respectively.
All catalogues constructed in this paper are released to the
public (see Section 8) via Vizier and the eROSITA web pages at
https://erosita.mpe.mpg.de/dr1/AllSkySurveyData_dr1/Catalogues_dr1/
(files 4-12).
