EROS and MACHO combined limits on planetary-mass dark matter in the galactic halo
C Alcock, RA Allsman, D Alves, R Ansari… - The Astrophysical …, 1998 - iopscience.iop.org
The EROS and MACHO collaborations have each published upper limits on the amount of
planetary-mass dark matter in the Galactic halo obtained from gravitational microlensing
searches. In this Letter, the two limits are combined to give a much stronger constraint on the
abundance of low-mass MACHOs. Specifically, objects with masses 10$\mathstrut {^{-7}} $
M $\mathstrut {_ {{\odot}}} $ ≲ m ≲ 10$\mathstrut {^{-3}} $ M $\mathstrut {_ {{\odot}}}
$ make up less than 25% of the halo dark matter for most models considered, and less than …
