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 catalogue WDSLOAN10 has been constructed by spectroscopically
selecting white dwarfs and subdwarfs in the Sloan Digital Sky Survey
Data Release 10. It offers Teff, log(g) and mass for hydrogen
atmosphere white dwarf stars (DAs) and helium atmosphere white dwarf
stars (DBs), and estimatives of calcium/helium abundances for the
white dwarf stars with metallic lines (DZs) and carbon/helium for
carbon dominated spectra DQs.
The catalog 1WHSP is the result of a multi-frequency selection for
blazars like SED, further filtered using IR-radio and IR-X-ray
flux-ratios. The sample assembled contains almost 992 sources of HSP
blazars, of which 425 are previously known blazars, 151 new
identifications and 416 blazar candidates. On the very high energy
trend, 299 are confirmed GeV gamma-ray photons emitters and 36 have
already been detected in the TeV band.
