Radio Astronomy
My research in Radio Astronomy
The National Centre for Radio Astronomy (NCRA) Pune, India, hosts one of the most powerful radio telescopes in the world at low frequencies (50 MHz-1400 Mhz) called the Giant Meter wave Radio Telescope (GMRT) . After joining NCRA in 2008, I have been working on various computational aspects of radio transients observation using the GMRT. Some of the techniques which are employed to observe transients are identical to the techniques employed to observe radio pulsars.

My notes
I have been learning one thing or another at various points of time, and found it very useful (at least for me !) to write things down. Here are some of my notes which are neither properly checked nor edited (if you want to help me in that please let me know !).
