Reading:

I have been reading the supernova article of my professor Dr. Reynolds . This article was about the supernovae and supernova remnants, their observed properties, their classification. Also there was an interesting summary of different observations. At the end there was also some theory which explained the observations.
Also I have been reading the thesis of David Allen Moffett, which was written at NCSU for the Degree of Master of Sciences, and which concentrated primarily on the studies of supernova remnants W49B and 3C391. More precisely, he studied polarization of radio emission from those remnants, their synchrotron radiation, and remnant age. Also he had done spectral index and total intensity studies.
In addition to all of this I have been doing some work on archiving files which were consuming a big space on the disk.

Research interests:

My research is concentrated on data reduction of UV data of different supernova remnants(SNR in short). Right now I am doing some job on SNR 3c397. The observations are done in VLA(Very Large Array), which is loccated in New Mexico, and wich is basically an interferometer, made of an array of 21(or more) antenas, which are placed in the shape of Y. The information in UV files is the Fourrier Transform of the radiointensity of the sky-region. The function of sky brightness is being broken into Fourrier series components, and each pair of antenas(each baseline) gives you one of those. Later the data in these UV files is reduced with appropriate software, called AIPS (Astronomical Immage Processing System), which turns those files into the maps of radiointensity of the sky-region being observed. During this the software adds the Fourrier Series components, in order to receive the sky brightness function. However, because of limitations in information, we have only very few components, and this causes a lot of noise. The function which should be smooth begins to appear having very little wigles. There are different algorithms used to reduce the amount of noise in the immage. The ones that we use are CLEAN and MEM(Maximum Enthropy Method).
Thus, we receive the radio-immage of the remnant. During this reduction a huge amount of information of course is lost. A lot of conclusions can be made by comparing the radio-immages of a remnant with its optic, infrared, and X-ray immages.

Here is the abstract which describes my work of Summer/95.

General Interests:

Playing violin, singing. Playing chess(the interest toward the later one is rather inconstant: one day I am a maniac of chess, the other day--pffff!)

More personal info:

I am a physics student here at North Carolina State University, and the coming year I am going to be a sophomore, in junior standing in physics and Mathematics.
I am born on 01/25/1977. Since my childhood I have been in following countries: Georgia, Russia, France(lived for 1.5 year over there), Germany, Spain, and now US. Where am I from? I am from Yerevan, which is the capital of Armenia. What?!...You don't know much about Armenia?!...Check http://www.darmstadt.gmd.de/~baloian/armenia.html in order to learn more about it!
An excellent page --pictures, music, and text featuring the history and the present of Armenia, it's ancient and modern art.
In the case if you want to know more info about me, here is the adress of my personal page(can't link to it): http://wonka.physics.ncsu.edu/~areg/areg.html. Enjoy!

This is Khor-Virap, a monastery complex in the Western part of Armenia, near Yerevan, with biblical mount Ararat (where Noah came down after the Great Flood), which is a sacred mountain for the Armenians(like Olympus for the ancient Greeks), and which symbolizes Armenian People.
