Skills & Professional Experiences:

Optical observations:

Photometric and polarimetric observations of ~56 nights from 1.04-m ARIES Sampurnand Telescope (ST), 1.3-m ARIES Devasthal Fast Optical Telescope (DFOT), 1.2-m Mount Abu Infra-Red Observatory (MIRO).

 

X-ray & UV observations:

I have observed active ultra-fast rotators as the Principal Investigator in X-ray and UV band from ASTROSAT satellite. Recently four proposals as Principal Investigator (PI) from Astrosat Satellites have been accepted in Announcement of Opportunity Cycle AO-02, AO-04, and AO-07. 


Scientific Data Handling:

I can very efficiently handle X-ray & UV data from almost all space-based observatories including XMM-Newton, Swift, Chandra, ASTROSAT, ROSAT, Suzaku, and other satellites.


I also have very good expertise in handling optical and infrared (IR) data, with experience in dealing with photometric and polarimetric data from several ground-based observatories viz. ARIES ST, ARIES DFOT, IUCAA Girawali Observatory Telescope, Goddard Robotic Telescopes, Ege University Observatory Telescopes, ASAS, SuperWASP, etc. as well as space-based observatories viz. Kepler, Hipparcos, etc.


Scientific Packages & tools:

I do programming mostly on Python. Besides this I use different programming languages  such as IDL, Unix Shell, Fortran, tcl/tk, IRAF, C++, R, etc.

For X-ray data reduction and analysis I use HEASOFT, FTOOLS, CIAO (for Chandra), SAS (for XMM-Newton) softwares. For optical and IR data reduction I use SCISOFT, IRAF, DAOPHOT, Anaconda packages. For plotting I use Python, Gnuplot, SM, and pgplot. Besides I use other softwares like LaTeX, Windows Office, Open Office, etc.
 

I have made automatic flare detection algorithms and python code from Kepler data. I also made codes for automatic reduction and analysis of a large amount of X-ray data. 

 

Operating systems:

Unix/Linux, Windows, Mac​
