Abstract:
Data from the Gaia satellite is 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 from Gaia DR3 down to
magnitude G∼20, creating a homogeneous catalogue of clusters including
many new objects. We use the HDBSCAN algorithm to recover clusters. We
validate our clusters using a statistical density test and a Bayesian
convolutional neural network for colour-magnitude diagram
classification. We infer basic astrometric parameters, ages,
extinctions, and distances for the clusters in the catalogue. We
recover 7200 clusters, 2420 of which are candidate new objects and
4780 of which crossmatch to objects in the literature, including 134
globular clusters. A more stringent cut of our catalogue contains 4114
highly reliable clusters, 749 of which are new. Owing to the scope of
our methodology, we are able to tentatively suggest that many of the
clusters we are unable to detect may not be real, including 1152
clusters from the Milky Way Star Cluster (MWSC) catalogue that should
have been detectable in Gaia data. Our cluster membership lists
include many new members and often include tidal tails. Our
catalogue's distribution traces the galactic warp, the spiral arm
structure, and the dust distribution of the Milky Way. While much of
the content of our catalogue contains bound open and globular
clusters, as many as a few thousand of our clusters are more
compatible with unbound moving groups, which we will classify in an
upcoming work. We have conducted the largest search for open clusters
to date, producing a single homogeneous star cluster catalogue which
we make available with this paper.
Description:
We present five tables.
Clusters: the main catalogue (Table 3).
Clusters_rejected: an addendum to Table 3 containing rejected clusters
in the Magellanic clouds or fragments of stellar streams. Not analysed
in the paper, but included for completeness.
Members: members of clusters in the main catalogue.
Members_rejected: members of clusters in the addendum to Table 3.
Crossmatches: a table of all clusters crossmatched against with IDs
corresponding to clusters in the main catalogue (Table B.1)

Global notes:
Note (G1): set to 99 for clusters with an SNR greater than approximately 38
(due to numerical precision limit in our pipeline/scipy).
Note (G2): Human-assigned CMD class as follows:
FP = false positive
FP? = false positive ?
TP = true positive
TP? = true positive ?
Note (G3): Type of crossmatch as follows:
1:1 = one to one
1:m = one to many
m:1 = many to one
m:m = many to many
blank for new object
