About me (briefly)

I am a scientist-astronomer at the National Radio Astronomy Observatory (NRAO) working primarily on the Expanded Very Large Array (EVLA) project. When completed, the EVLA will be the world's best radio telescope and most sensitive interferometer operating between 1 and 50 GHz. Before joining NRAO, I was an astronomer at the world's largest single dish radio telescope: The 305-m (1000 ft) Arecibo Radio Telescope of the National Astronomy and Ionosphere Center (NAIC).

My research is focused on high angular resolution radio observations of extragalactic objects known as LIRGs (Luminous Infrared Galaxies) and ULIRGs (Ultra Luminous Infrared Galaxies), to study both the structure and the kinematics of the central regions in these galaxies. This research includes imaging of these galaxies in radio continuum, in HI 21 cm absorption, and in OH 18 cm megamaser emission.

For this research, and in order to study the nuclear active regions of these galaxies at very high spatial resolution, I mainly use the Very Long Baseline Array (VLBA) of the NRAO. However, the radio emission from these IR galaxies is very weak. So, in order to have successful observations, the Very Large Array (VLA) of the NRAO, with its twenty seven 25-meter antennas, participates in these sensitivity limited observations. In some of these observations, the giant 305-meter Arecibo radio telescope of the NAIC is used along with both the VLBA and the VLA. Click here to visit the VLBI page of the Arecibo Observatory
I am also actively involved in sensitive VLBI imaging of the radio continuum emission from very high redshift quasars, both radio-loud and radio-quiet. These quasars are believed to be near the epoch of re-ionization, i. e., when the first stars and galaxies started to form (less than 1 billion years after the Big Bang). We have recently expanded this work to sum-millimeter galaxies (SMGs) at z~2-3.

I continue to be involved in the various ALFA (Arecibo L-Band Feed Array) surveys that target extragalactic sources. These surveys are ALFALFA (The Arecibo Legacy Fast ALFA Survey), AGES (Arecibo Galaxy Environment Study), AUDS (ALFA Ultra Deep Survey), and ZOA (Zone of Avoidance). These are all extragalactic HI surveys that make-up the E-ALFA consortium. I am also a member of the GALFACTS (GALFA Continuum Transit Survey), which is a spectro-polarimetric survey that targets both galactic and extragalactic sources.


History

If you are interested in history, then you should read about the history of my people, the Armenian people, a real but painful example of a nation's survival for thousands of years (3500 years!). Here are some links:

Armenian History: a web site by Yuri Babayan.

The Armenian Genocide: The first genocide of the 20th century. This year is the 94th anniversary of the Armenian Genocide, in which 1.5 million armenians have perished in the turkish occupied Western Armenia. To read more, visit the Armenian National Institute

You can also read about the armenian genocide at the following web sites:
Genocide 1915

Armeniapedia: the online Armenia Encyclopedia
ArmenianHouse.org: an electronic library featuring a huge collection of documents on Armenian literature, history, religion and anything else Armenia-related
