- Description:
- From the Gaia DR2 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (µ_tot >150mas/yr) passing a background source in the next decades. Using Gaia DR2 photometry we determine an approximate mass of the lens, which we use to calculate the expected microlensing effects. This yields 3914 microlensing events by 2875 different lenses between 2010 and 2065 with expected shifts larger than 0.1 mas between the lensed and unlensed positions of the source. 513 of those are expected to happen between 2014.5 - 2026.5 and might be measured by Gaia. For 127 events we also expect a magnification between 1 mmag and 3 mag.

- Description:
- From the Gaia eDR3 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (μ > 100 mas/yr) passing a background source in the next decades. Using Gaia DR3 photometry we determine an approximate mass of the lens, which we use to calculate the expected microlensing effects. This yields 4842 microlensing events by 3791 different lenses between 2010 and 2066 with expected shifts larger than 0.1 mas between the lensed and unlensed positions of the source. The past events might be interested when analyzing the individual Gaia measurements). 685 of those are expected to happen within the next decade (2021-2031). For 140 events we also expect a magnification between 1 mmag and 0.6 mag.

- Title:
- ATLAS DR1 - VST ATLAS Survey
- Date:

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- This DSA hosts data release 1 of the ATLAS Survey housed at the Wide Field Astronomy Unit at the Univeristy of Edinburgh. The initial aim of ATLAS is to survey 4500 deg2 of the Southern Sky at high galactic latitudes to comparable depths to the SDSS in the North. The VST ATLAS will be the first step towards a panoramic digital survey of the Southern Sky in the optical bands. The ATLAS will complement the proposed VISTA Hemisphere Survey in the South.

- Publisher:
- The GAVO DC team
- 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.
68. 1BIGB catalog

- 1BIGB catalog
- Short Name:

- 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.
