St. Xavier College Student Registry, 1840-1870

The St. Xavier College Student Registry, 1840-1870, (also referred to as the Alumnorum Album Regula) is a handwritten, bound ledger listing students enrolled in coursework during the sessions 1840-1841 through 1869-1870. The ledger includes pages with columns for name, parent or guardian, residence, date of entrance, rank (day or boarder), age, religion, department, and remarks. The registry also includes the college\u27s schedule, curriculum, rules, and expectations of both boarders and day scholars. Many of the student names also appear in the Catalogue of Students published annually in the college\u27s course catalogs, but not all.https://www.exhibit.xavier.edu/st_xavier_college_documents/1000/thumbnail.jp

An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

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 of the source star of the long-duration (t_E ~ 270 days), high-magnification microlensing event MOA-2011-BLG-191/OGLE-2011-BLG-0462, in the direction of the Galactic bulge. HST imaging, conducted at eight epochs over an interval of six years, reveals a clear relativistic astrometric deflection of the background star's apparent position. Ground-based photometry shows a parallactic signature of the effect of the Earth's motion on the microlensing light curve. Combining the HST astrometry with the ground-based light curve and the derived parallax, we obtain a lens mass of 7.1 +/- 1.3 M_Sun and a distance of 1.58 +/- 0.18 kpc. We show that the lens emits no detectable light, which, along with having a mass higher than is possible for a white dwarf or neutron star, confirms its BH nature. Our analysis also provides an absolute proper motion for the BH. The proper motion is offset from the mean motion of Galactic-disk stars at similar distances by an amount corresponding to a transverse space velocity of ~45 km/s, suggesting that the BH received a modest natal 'kick' from its supernova explosion. Previous mass determinations for stellar-mass BHs have come from radial-velocity measurements of Galactic X-ray binaries, and from gravitational radiation emitted by merging BHs in binary systems in external galaxies. Our mass measurement is the first ever for an isolated stellar-mass BH using any technique
