Applications are invited for a postdoctoral research position at the Space Telescope Science Institute (STScI) to work in collaboration with Dr. Kailash C.Sahu. The successful applicant will participate in analysis and interpretation of HST imaging data of microlensing events. In particular, we have a large HST program with WFC3/ACS to monitor some 1.5 million stars towards the Galactic bulge for 3 years. The principal aim of this large program is to detect microlensing events caused by non-luminous isolated black holes and neutron stars in the Galactic disk and bulge, and measure their masses. The unique capability of HST imaging for microlensing observations is the addition of high-precision astrometry, allowing detection of the astrometric shift of the source during the event. Combined with the lens parallax, provided by the HST event light curve, the astrometric shift provides a direct measurement of the lens mass.
In addition, the data will have many other applications, including a more accurate determination of the microlensing optical depth, faint variable stars, bulge proper motions and kinematics, and a deep luminosity function of the disk and bulge stars. Opportunities for independent research will also be available.
The initial appointment will be for one year, starting in the summer or fall of 2013, or as soon thereafter as a suitable candidate is found. The initial appointment will be for one year, and renewals for future years, up to a total of three, will depend upon performance and availability of grant funds.
Candidates must hold a Ph.D. degree and should be observational stellar astronomers with expertise and interest in crowded-field photometry and/or stellar astrophysics and/or microlensing
