Ground-based Parallax Confirmed by Spitzer: Binary Microlensing Event MOA-2015-BLG-020 [PDF]

, 2023
We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (∼63 days) and thus the light curve deviates significantly from the lensing model that is based on the rectilinear lens-source ...

Microlensing search for extra solar planets [PDF]

, 2015
Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

Galactic microlensing : binary-lens light curve morphologies and results from the Rosetta spacecraft bulge survey [PDF]

, 2014
For 20 years now, gravitational microlensing observations towards the Galactic bulge have provided us with a wealth of information about the stellar and planetary content of our Galaxy, which is inaccessible via other current methods.

Microlensing for extrasolar planets : improving the photometry [PDF]

, 2013
Gravitational Microlensing, as a technique for detecting Extrasolar Planets, is recognised for its potential in discovering small-mass planets similar to Earth, at a distance of a few Astronomical Units from their host stars.

“Industrial-scale” Black Hole Selection without a Satellite

The Astrophysical Journal
The forthcoming GRAVITY+ instrument promises to usher in an era of “industrial-scale” mass measurements of isolated black holes (BHs), with the potential to assemble a sample of many tens of BHs via interferometric microlensing over several years.
