Abstract

We present the results of the most comprehensive survey of the Galactic plane
in very high-energy (VHE) gamma-rays, including a public release of Galactic
sky maps, a catalog of VHE sources, and the discovery of 16 new sources of VHE
gamma-rays. The High Energy Spectroscopic System (H.E.S.S.) Galactic plane
survey (HGPS) was a decade-long observation program carried out by the H.E.S.S.
I array of Cherenkov telescopes in Namibia from 2004 to 2013. The observations
amount to nearly 2700 h of data, covering the Galactic plane at longitudes from
l = 250 deg to 65 deg and latitudes |b| < 3 deg. In addition to the
unprecedented spatial coverage, the HGPS also features a relatively high
angular resolution (0.08 deg), sensitivity (1.5% Crab flux for point-like
sources), and energy range (0.2-100 TeV). We constructed a source catalog with
a systematic procedure for both source detection and characterization of
morphology and spectrum. We present this method, including the introduction of
a model component to account for unresolved, large-scale emission along the
Galactic plane. In total, the resulting HGPS catalog contains 78 VHE sources,
of which 14 are not reanalyzed here. Where possible, we provide a firm
identification of the VHE source or plausible associations with sources in
other astronomical catalogs. We also studied the characteristics of the VHE
sources with source parameter distributions. 16 new sources were previously
unknown or unpublished, and we individually discuss their identifications or
possible associations. We firmly identified 31 sources as pulsar wind nebulae
(PWNe), supernova remnants (SNRs), composite SNRs, or gamma-ray binaries. Among
the 47 sources not yet identified, most of them (36) have possible associations
with cataloged objects, notably PWNe and energetic pulsars that could power VHE
PWNe.
