A basic calculation suggests that angular precision on the order of \(10\) microarcseconds in the relative opening angle could be achieved in a single night’s observation of two bright stars. We argue this technique could allow robust high-precision measurements of the relative astrometry of the two sources. We rigorously calculate the observables and contrast this new interferometric technique with the Hanbury Brown & Twiss intensity interferometry. The precision, accuracy, and homogeneity of both astrometry and photometry are unprecedented. The apparent astrometric shift of the background star due to microlensing, which is proportional to M 1 / 2, is 1 milliarcsecond for a 10 M black hole at 4 kpc lensing a background star at 8 kpc ( Fig. This time 10 PhD theses, defended between 16 December 2021 and 15 December 2022, were submitted. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. A new refinement of this idea is developed, in which two photons from different sources are interfered at two separate and decoupled stations, requiring only a slow classical information link between them. However, only the addition of WFIRST astrometry will enable us to measure the precise masses of these objects through astrometric microlensing. It has been recently proposed that stations in optical interferometers would not require a phase-stable optical link if instead sources of quantum-mechanically entangled pairs could be provided to them, potentially enabling hitherto prohibitively long baselines. astrometry of the Euclid space-based imaging. In the summer of 2016, Jessica joined the faculty of the UC Berkeley astronomy department.Improved quantum sensing of photons from astronomical objects could provide high resolution observations in the optical benefiting numerous fields, including general relativity, dark matter studies, and cosmology. accurate colors required to obtain precise galaxy photometric redshifts. She was also an NSF Astronomy and Astrophysics postdoctoral fellow at the Institute for Astronomy (IfA) in the University of Hawaii, Manoa before joining the IfA faculty in 2013. After completing her PhD, she was awarded a Millikan Postdoctoral Fellowship in Observational Astronomy at Caltech. She worked as a software engineer in silicon valley for 3 years before returning to academia to pursue her PhD in astronomy and astrophysics at UCLA, which was granted in 2008. Jessica Lu received her undergraduate degree in physics from the MIT in 2000.
