Gravitational astroparticle physics

by Ranjan Laha (CERN)

2001 (Ångström)




In this talk, I will discuss two new techniques in order to discover new physics in the dark sector.  In the first part of my talk, I will be talking about detection of primordial black holes via Hawking radiation.  After a brief introduction to primordial black holes, I will discuss how the observation of positrons responsible for the Galactic Centre 511 keV gamma-ray line can be used to probe a completely new mass range for primordial black holes.  In the second part of my talk, I will show that gravitational wave emission from neutron star binaries can be used discover any generic long-ranged muonic force due to the inevitable abundance of muons inside neutron stars.  Such a force will change the dynamics of the binary system.  The limits attainable with this technique are many orders of magnitude stronger than any other previous constraints.
