Microlensing of fast and slow compact objects
Manish Tamta, Nirmal Raj, Himanshu Verma
Gravitational microlensing constraints on non-standard compact objects are conventionally derived assuming lenses trace the dark matter halo with velocities following a Maxwell-Bol…
First direct detection constraints on Planck-scale mass dark matter with multiple-scatter signatures using the DEAP-3600 detector
P. Adhikari, R. Ajaj, M. Alpízar-Venegas +94
Dark matter particles with Planck-scale mass () arise in well-motivated theories and could be produced by several cosmological mechanisms. Using a blin…
Subaru through a different lens: microlensing by extended dark matter structures
Djuna Croon, David McKeen, Nirmal Raj +1
We investigate gravitational microlensing signals produced by a spatially extended object transiting in front of a finite-sized source star. The most interesting features arise for…
Gravitational microlensing by dark matter in extended structures
Djuna Croon, David McKeen, Nirmal Raj
Dark matter may be in the form of non-baryonic structures such as compact subhalos and boson stars. Structures weighing between asteroid and solar masses may be discovered via grav…
