Yes, the admissions were over in April itself.

Hello Jyoti,
It's very tough to say which department of IISc is better than the other. In fact each department competes with another for academic excellence in this institute. I would rather advise you to select the topic that fascinates you the most amongst a variety of subjects that you are eligible. I am attaching a link for you:

-Indian Institute of Space Physics (Kolkata)
-Raman Research Institute (Bangalore)
-IUCAA (Pune)
