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…
Light and colour variations of Mira variables in the Small Magellanic Cloud
Yoshifusa Ita, John W. Menzies, Patricia A. Whitelock +6
The goal of this paper is to characterise the light variation properties of Mira variables in the Small Magellanic Cloud. We have investigated a combined optical and near infrared…
Luminous AGB variables in the dwarf Irregular Galaxy, NGC 3109
J. W. Menzies, P. A. Whitelock, M. W. Feast +1
In a shallow near-infrared survey of the dwarf Irregular galaxy, NGC 3109, near the periphery of the Local Group, we have found eight Mira variables, seven of which appear to be ox…
First assessment of the binary lens OGLE-2015_BLG-0232
E. Bachelet, V. Bozza, C. Han +51
We present an analysis of the microlensing event OGLE-2015-BLG-0232. This event is challenging to characterize for two reasons. First, the light curve is not well sampled during th…
A near infrared variable star survey in the Magellanic Clouds: The Small Magellanic Cloud data
Yoshifusa Ita, Noriyuki Matsunaga, Toshihiko Tanabe +12
A very long term near-infrared variable star survey towards the Large and Small Magellanic Clouds was carried out using the 1.4m InfraRed Survey Facility at the South African Astro…
OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?
M. Dominik, E. Bachelet, V. Bozza +40
(abridged) Using the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale ~ 300 d, we present a methodology for identifying the na…
