Extracted sources from the Bochum Galactic Disk Survey. We provide
mean photometry in U, B, V, z, r, and i bands. Note that sources in
different bands are not matched. Also, sources sitting in the regions
imaged in multiple fields have not been matched even within one band.
In i and r, BGDS light curves are available. See related services for
details.
This catalog presents the 1-100 GeV spectral energy distribution
(SED) for a population of 148 high-synchrotron-peaked blazars (HSPs)
recently detected with Fermi-LAT as part of the First Brazil-ICRANet
Gamma-ray Blazar catalogue (1BIGB). A series of two works describe
details on the broadband analysis https://arxiv.org/abs/1609.08501
(paper 1), and the calculation of the gamma-ray SEDs
https://arxiv.org/abs/1804.08801 (paper 2). Most of the 1BIGB sources
do not appear in previous Fermi-LAT catalogues and their gamma-ray
spectral properties are presented here for the first time,
representing a significant new extension of the gamma-ray blazar
population. Since the 1BIGB sample was originally selected from an
excess signal in the 0.3-500 GeV band, the sources stand out as
promising TeV blazar candidates, potentially in reach of the
forthcoming very-high-energy (VHE) gamma-ray observatory, CTA. The
flux estimates presented here are derived considering PASS8 data,
integrating over more than 9 years of Fermi-LAT observations. The full
broadband fit between 0.3-500 GeV presented in paper 1 for all sources
was reevaluated in paper 2, updating the power-law parameters with
currently available Fermi-LAT dataset. The importance of these sources
in the context of VHE population studies with both current instruments
and the future CTA is evaluated in paper 2. To do so, a subsample of
1BIGB sources was selected and had their gamma-ray SEDs extrapolated
to the highest energies, properly accounting for absorption due to the
extragalactic background light. Those extrapolations were compared to
the published CTA sensitivity curves and their detectability by CTA
was estimated. Two notable sources from our sample, namely 1BIGB
J224910.6-130002 and 1BIGB J194356.2+211821, are discussed in greater
detail in paper 2. All gamma-ray SEDs, which are shown here for the
first time, are made publicly available via the Brazilian Science Data
Center (BSDC) service, maintained at CBPF, in Rio de Janeiro.

The Bochum Galactic Disk Survey is a project to monitor the stellar
content of the Galactic disk in a 6 degree wide stripe centered on the
Galactic plane. The data has been recorded from September 2010 to
September 2019 with the RoBoTT Telecsope at the
Universitaetssternwarte Bochum near Cerro Armazones in the Chilean
Atacama desert. It contains measurements of more than 2x10^7 stars.
The second and final data release contains follow-up observations from
January 2017 to September 2019 in Sloan r and i and intermittent
measurements in Johnson UVB, Sloan z and the narrowbands OIII, NB,
Halpha and SII.
This service exposes the light curves of stars produced by the Bochum
Galactic Disk Survey; several million light curves are provided in the
SDSS i and r bands. The lightcurves are published per-band and are
also available through obscore.
