Abstract:
After some reminiscences about my time in
Stockholm, I will talk about work
with my group on the question of
the nature of the Dark Matter in the Universe.
I will discuss five topics:
i) Cosmological
probes of neutrino properties;
ii)
Regarding WIMP searches: status and what is going on with DAMA?
iii) Axions and
Primordial Black Holes;
iv) Dark Stars
(the first stars could have been powered by dark matter rather
than by fusion) and
v)
New ways to test the nature of Dark matter: the GAIA satellite and stellar
streams
as a test of Cold
Dark Matter.
