Recent observations of the gravitational wave by LIGO motivates investigations for the existence of Primordial Black Holes (PBHs) as a candidate for the dark matter. We propose quasar gravitational microlensing observations in Infrared to the sub-millimeter wavelengths by sub-lunar PBHs as lenses. The advantage of observations in the longer wavelengths is that the Schwarzschild radius of the lens is of the order of the wavelength (i.e. $R_{\rm sch}\simeq \lambda$), so the wave optics features…

Microlensing of stars, e.g. in the Galactic bulge and Andromeda galaxy (M31), is among the most robust, powerful method to constrain primordial black holes (PBHs) that are a viable candidate of
Light deflection by squashed Kaluza-Klein black holes in a plasma medium
We study motions of photons in an unmagnetized cold homogeneous plasma medium in the five-dimensional charged static squashed Kaluza-Klein black hole spacetime. In this case, a photon behaves as a
