Gravitational microlensing in NUT space

We study the theoretical signature of magnetic masses on the light curve of the gravitational microlensing effect in NUT space. The light curves for microlensing events in NUT space are presented and contrasted with those caused by lensing produced by normal matter. In the next step, associating the magnetic mass to the massive astrophysical compact halo objects (MACHOs), we try to see the effect on the light curves of microlensing candidates observed by the MACHO group. The presence or absence of this feature in the observed microlensing events can shed light on the question of the existence of magnetic masses in the Universe.
