The DFBS Spectroscopic Database and the Armenian Virtual Observatory

Data Science Journal, 2009
The Digitized First Byurakan Survey (DFBS) is the digitized version of the famous Markarian Survey. It is the largest low-dispersion spectroscopic survey of the sky, covering 17,000 square degrees at galactic latitudes |b|>15.

Discovery of optically faint obscured quasars with Virtual Observatory tools

, 2004
We use Virtual Observatory (VO) tools to identify optically faint, obscured (i.e., type 2) active galactic nuclei (AGN) in the two Great Observatories Origins Deep Survey (GOODS) fields.

Using Virtual Observatory techniques to search for Adaptive Optics suitable AGN

, 2009
Until recently, it has been possible only for nearby galaxies to study the scaling relations between central black hole and host galaxy in detail. Because of the small number densities at low redshift, (luminous) AGN are underrepresented in such detailed

The Millennium Run Observatory: First Light

, 2012
Simulations of galaxy evolution aim to capture our current understanding as well as to make predictions for testing by future experiments. Simulations and observations are often compared in an indirect fashion: physical quantities are estimated from the ...

Identification of new cataclysmic variables in the 1RXS and USNO-B1.0 catalogs

, 2010
As a result of applying the original optical variability search method on publicly available data, we have found eight new cataclysmic variables and two possible Optically Violent Variable quasars among the previously unidentified X-ray sources in the ...

Safeguarding Old and New Journal Tables for the VO: Status for Extragalactic and Radio Data

, 2009
Independent of established data centers, and partly for my own research, since 1989 I have been collecting the tabular data from over 2600 articles concerned with radio sources and extragalactic objects in general. Optical character recognition (OCR) was

Shared nomenclature and identifiers for telescopes and instruments

EPJ Web of Conferences, 2018
In the context of sharing public data, science results are expected to be reproducible and therefore we need full traceability of the origin of the data. On the documentalist side, there is a need to relate instrumental origins to the published data.
