Title:: ARI Catalog of Catalogs
Short Name:: katkat_web
Date:: 27 Dec 2024 08:31:00
Publisher:: The GAVO DC team
Description:: ARI katkat is a catalog of star catalogues in the spirit of G. Teleki's catalog of star catalogs (`1989BOBeo.140..131T`_ and references in there). It contains 2573 catalogs suitable for astrometric usage, starting with Flamsteed (1835) and ending in the 1970ies. For almost all of them, there is a column description file (as PDF, and unfortunately sometimes in German) and the digitized content. .. _1989BOBeo.140..131T: http://ads.g-vo.org/abs/1989BOBeo.140..131T

Title:: ARIGFH identified objects
Short Name:: arigfh scs
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: ARI's "Geschichte des Fixsternhimmels" is an attempt to collect all astrometrically useful observations from before ca. 1970 in a way comparable to what has been done to construct the FK* series of fundamental catalogs. About 7e6 published positions are included. In GAVO's DC, we provide tables of identified and non-identified stars together with the master catalog that objects were identified against.

Title:: ARIHIP astrometric catalogue
Short Name:: arihip cone
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: The catalogue ARIHIP has been constructed by selecting the 'best data' for a given star from combinations of HIPPARCOS data with Boss' GC and/or the Tycho-2 catalogue as well as the FK6. It provides 'best data' for 90 842 stars with a typical mean error of 0.89 mas/year (about a factor of 1.3 better than Hipparcos for this sample of stars).

Title:: Astrometric Microlensing Events Predicted from Gaia DR2
Short Name:: am lensing 2
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
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.

Title:: Astrometric Microlensing Events Predicted from Gaia eDR3
Short Name:: am lensing 2
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
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:: 1BIGB: First Brazil-ICRANet Gamma-Ray Blazar Catalogue
Short Name:: 1BIGB SSAP
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
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: :bibcode:`2017A&A...598A.134A`, and the calculation of the gamma-ray SEDs :bibcode:`2018MNRAS.480.2165A`. The 1BIGB sample was originally selected from an excess signal in the 0.3-500 GeV band 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
