Gravitational Microlensing Events Due to Stellar‐Mass Black Holes
Gravitational Microlensing Events Due to Stellar‐Mass Black Holes
We present an analysis of the longest timescale microlensing events discovered by the MACHO Collaboration during a 7 year survey of the Galactic bulge. We find 6 events that exhibit very strong microlensing parallax signals due, in part, to accurate photometric data from the GMAN and MPS collaborations. The microlensing …
