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…

A more probable explanation for a continuum flash in the direction of a redshift 11 galaxy

Charles L. Steinhardt, Michael I. Andersen, Gabriel B. Brammer +5

Recent work reported the discovery of a gamma-ray burst (GRB) associated with the galaxy GN-z11 at . The extreme improbability of the transient source being a GRB in the…

Transit timing variations in the WASP-4 planetary system

John Southworth, M. Dominik, U. G. Jorgensen +25

Transits in the planetary system WASP-4 were recently found to occur 80s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that…

Physical properties and transmission spectrum of the WASP-74 planetary system from multi-band photometry

L. Mancini, J. Southworth, P. Molliere +32

We present broad-band photometry of eleven planetary transits of the hot Jupiter WASP-74b, using three medium-class telescopes and employing the telescope-defocussing technique. Mo…

First Results From The Hertzsprung Song Telescope: Asteroseismology Of The G5 Subgiant Star {\Mu}Her

F. Grundahl, M. Fredslund Andersen, J. Christensen-Dalsgaard +26

We report the first asteroseismic results obtained with the Hertzsprung SONG Telescope from an extensive high-precision radial-velocity observing campaign of the subgiant muHerculi…

Spitzer Observations of OGLE-2015-BLG-1212 Reveal a New Path to Breaking Strong Microlens Degeneracies

V. Bozza, Y. Shvartzvald, A. Udalski +98

Spitzer microlensing parallax observations of OGLE-2015-BLG-1212 decisively breaks a degeneracy between planetary and binary solutions that is somewhat ambiguous when only ground-b…
