Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets

Youn Kil Jung, Weicheng Zang, Hanyue Wang +41

We complete the publication of all microlensing planets (and ``possible planets'') identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields…

An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

Kailash C. Sahu, Jay Anderson, Stefano Casertano +90

We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…
