Although it is not possible to directly observe the highly redshifted galaxies, but their signature as absorp- tion line in the background quasar spectrum allow us to study them in both optical and radio regions. In this regard we study the quasar-galaxy pair (QGP) J1443+0214 with zqso =1.82, zabs = 0.3714. The foreground galaxy in this QGP is identified by the detec- tion of emission lines in the SDSS spectrum of QSO. The foreground galaxy is invisible otherwise. The QGP J1443+0214 was observed on 2012 June 2 (5.7h on source) with Giant Me- terwave Radio Telescope (GMRT) using a baseband bandwidth of 4.17 MHz split into 512 spectral channels centered on the redshifted 21-cm frequency of foreground galaxy. We reduce the data using Astronomical Image Processing System (AIPS) to obtain HI 21-cm absorption line. This reduction process consists of steps like loading the data into AIPS, editing and flagging the bad data, calibrating it through various steps of gain calibration, bandpass calibration and finally the self calibration. Further, we fit Gaussian components to the continuum and absorption line profile separately; then divide the continuum from multi-channel source data using Interactive Data Language (IDL). We estimate parameters like optical depth and spin temperature from this spectrum obtained.

In this project, I have learnt the basic properties of telescope along with a hands on practice with CCD data. Project has done under the supervision of Dr. B. J.

The objective is to store the data generated by the data logger of AWS into the database from where further manipulations can be done. After the data being stored, it is to be displayed on the web page. The technologies used for building web pages are PHP, JavaScript, CSS, and HTML. The main web page will display hourly statistics of current date. Monthly and yearly statistics will be displayed by clicking the buttons provided on the main web page.

We selected 1850 open star clusters from the catalogue of Dias et al. (2002). The fundamental parameters like age, distance, reddening , longitude, latitude and metallicity are also acquired from the same catalogue. We also studied the variation of different parameters of the clusters with Galactic parameters in different quadrants of the Galaxy. Our analysis show that most of the open clusters located along the spiral arms of our Galaxy. Project under supervision of Dr. R.K.S.
