Dark matter and its indirect detection

Ranjan Laha

CHEP, Indian Institute of Science

What is the Universe made up of?  Surprisingly, we do not know the answer to this basic question.  In this talk, I will introduce dark matter,
which comprises of 80% of the matter density of the Universe.  I will discuss some of the gravitational evidences that we have in favour of dark
matter.  I will then talk about its non-gravitational search strategy, in particular indirect detection.  I will discuss how various messengers can be
used to study the indirect detection of dark matter.  I will try to convey the various challenges that one encounters in these searches, and how one can
try to overcome them.  I will also discuss how discoveries can be made using this search strategy.
