Lenses aren’t always made of glass, sometimes they’re made of dark matter compact objects! Today’s paper explores if and how we can tell primordial black holes apart from dark black holes using gravitational microlensing measurements.
We’re not sure if Primordial Black Holes (PBHs) exist, but today’s authors might have seen evidence of them while observing the Andromeda Galaxy — and not just one PBH, but twelve!
Today’s paper shows us how to repurpose microlensing surveys to study clumps of dark matter drifting through space.
Today’s paper explores the impact of clumpy matter on gravitational lensing and measurements of the Hubble Constant.
There are numerous candidates for dark matter, including primordial black holes. Today’s paper addresses whether an upcoming NASA space telescope could detect these exotic black holes from the early universe.
Today’s paper explores how we can use simulations of stellar populations to rapidly estimate the identity of the lensing object in a microlensing event.
