- Description:
- 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.
73. 1BIGB catalog

- Description:
- 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.

- Description:
- 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.

- Description:
- Split spectra from the CALIFA DR3 cubes. This service serves one spectrum each per pixel in each cube where there is at least one valid spaxel. Where both V500 and COMB data is available, COMB spectra are served. WARNING: The individual spectra are not independent. Also, error estimates over wide spectral ranges based on the error estimates served here are unreliable.
