Glimpsing Dark Objects with Gaia
Today’s authors work out a full orbital solution for a binary microlensing system, indicating the method’s potential to probe the mass distribution of dark objects.
Gravitational waves through the looking glass
Gravitational waves are distorted by the objects that lie in their wake – how can we learn more about their journey through the cosmos?
Look! A Lensing!
Gaia can do astrometry very well. And it turns out it can also help us observe lensings.
Measuring Masses with Microlensing: A White Dwarf Magnifying Glass
An exciting white dwarf microlensing event is predicted to happen on November 11th, 2019! Today’s paper explains how this prediction was made and what we could learn from the microlensing event about the mass-radius relation of white dwarfs.
(Just can’t get enough) primordial black holes
The authors show that it’s possible to produce enough asteroid-mass primordial black holes to make them a viable dark matter candidate, without violating the new and very stringent constraints on the number of allowed primordial black holes from the Subaru Hyper Suprime-Cam.
Rogue One: The First Einstein Ring Measurements of A Free-Floating Planet
An OGLE microlensing event allowed researchers to find and measure the propeties of a rogue planet.
