Molecular hydrogen clouds can contribute substantially to the galactic halo dark matter and may lead to the birth of Massive Halo Objects (MHOs) observed indirectly by microlensing. We present a method to detect these molecular clouds in the halo of M31 using the Doppler shift effect. We also consider the possibility to directly observe MHOs in the halo of M31 via their infrared emission.

Abstract
Molecular hydrogen clouds can contribute substantially to the galactic halo dark matter and may lead to the birth of Massive Halo Objects (MHOs) observed indirectly by microlensing. We present a method to detect these molecular clouds in the halo of M31 using the Doppler shift effect. We also consider the possibility to directly observe MHOs in the halo of M31 via their infrared emission.File in questo prodotto:
