Telescopes and Other Facilities Used for Research

I have carried out astronomical observations since the first year of my work, 1986. I was a fellow of the Laboratory of the 2.6m telescope and made observations rather often. Altogether, I have observed a few hundred nights with BAO 2.6m and 1m Schmidt, and OHP 1.93m telescopes, as well as my projects have been accomplished with a number of other ground-based telescopes in USA, France, Spain, Italy, Russia, and Mexico. A number of surveys, databases, reduction and analysis software, and other facilities have been used too.








BAO 1m Schmidt telescope

The First Byurakan Survey (FBS) plates, as well as observations have been carried out to expand the FBS to Milky Way regions.


BAO 2.6m telescope

Since 1986, BAO-2.6 has been used for spectroscopy of FBS BSOs and SBS objects, as well as later for BIG objects.

SAO 6m telescope (BTA), Russia. We have used BTA for spectroscopic observations of BIG objects (collaboration with Burenkov, Dodonov, et al.

OHP 1.93m telescope

OHP-1.93 has been used for spectroscopic observations of FBS BSOs and BIG objects (collaboration with Verons).








OHP 1.2m telescope

Has been used for photometric observations of cataclysmic variable RX J1643.7+3402 (collaboration with Ilovaisky).


Hamburg 80cm Schmidt telescope, Calar-Alto, Spain

Hamburg Quasar Survey (HQS) plates have been used for optical identifications of X-ray sources.

Calar-Alto 2.2m telescope

This telescope has been used for observations of Akn 564 (collaboration with Engels) and fine analysis of its spectra.

Palomar Observatory 5m Hale telescope. We have observed spectra of SBS candidate BCDGs (collab. with Houck, Weedman, et al.).









INAOE 2.12m telescope, Cananea, Mexico. We have used this telescope to observe spectra of ROSAT AGN (collab. with Mujica & Chavushyan).


San Pedro Martir 2.12m telescope, Mexico. We have

used this telescope to observe spectra of ROSAT candidate AGN (coll. with Mujica &Chavushyan).

Asiago 1.82m Copernico telescope. This telescope has been used for spectroscopy of BIS objects (collaboration with Nesci, Rossi, and Gaudenzi).

Loiano 1.52m Cassini telescope. This telescope was used for spectroscopy of BIS objects (collaboration with Nesci, Rossi, and Gaudenzi).









Telescopio Nazionale Galileo 3.58m. This telescope has been used for spectroscopy of BIS objects (collab. with Nesci, Rossi, and Gaudenzi).

IRAS, IPAC, Caltech, USA

Optical identifications of 1577 IRAS PSC sources and the list of highest IR/opt flux ratio sources from FSC later observed by SST.

ROSAT, Germany. Optical identifications of 3000 ROSAT FSC sources using HQS and other databases. ROSAT AGN candidates for spectroscopy.

Spitzer Space Telescope (SST), USA. Observation of IRAS-FSC selected 28 highest IR/opt flux ratio sources. SST archives for new research.





Digitized First Byurakan Survey (DFBS). Using DFBS improves selection of blue stellar objects and late-type stars, as well as opens new opportunities.


Armenian Virtual Observatory (ArVO). ArVO is a project to provide tools and data for new astronomical research using DFBS database.


For most of our research we use DSS1/DSS2 providing blue, red and infrared sky images over the whole sky in FITS format.

Sloan Digital Sky Survey (SDSS), USA. SDSS is much deeper than DSS but covers only the fourth part. It is extremely useful for deeper research.









Vizier, CDS, Strasbourg, France. A database (catalog) of astronomical catalogs, giving online access to some 8000 catalogs having more than 1 billion objects.

SIMBAD, CDS, Strasbourg, France. This is online database (catalog) of astronomical objects, mostly used for galactic objects and giving all possible data.

ALADIN, CDS, France. A tool for visualization of astronomical images and overplotting catalogs. We have also used it for plotting images and showing structure.

SMART. It is the dedicated software for reduction of Spitzer IRS spectra. It was used for observations of our selected sources and archive studies.








ESO-MIDAS. One of the most important astronomical packages used for reduction of images, spectra, calculations and graphics.

We mostly use it for spectra.


SkyBoT VO software, IMCCE, France. We use it for search of asteroids in the DFBS database using its calculations for any epoch of observations.

NED, IPAC, Caltech, USA

The largest and most important extragalactic database. Most of my research is related to QSOs and galaxies; I use it very often.

HyperLEDA, Lyon, France

Second largest extragalactic database, however having more information on objects compared to NED. I have worked for it too.
