Nine-hour X-ray quasi-periodic eruptions from a low-mass black hole galactic nucleus.

In the past two decades, high-amplitude electromagnetic outbursts have been detected from dormant galaxies and often attributed to the tidal disruption of a star by the central black hole. X-ray emission from the Seyfert 2 galaxy GSN 069 (2MASX J01190869-3411305) at a redshift of z = 0.018 was first detected in July 2010 and implies an X-ray brightening by a factor of more than 240 over ROSAT observations performed 16 years earlier.

A close-pair binary in a distant triple supermassive black hole system.

Galaxies are believed to evolve through merging, which should lead to some hosting multiple supermassive black holes. There are four known triple black hole systems, with the closest black hole pair being 2.4 kiloparsecs apart (the third component in this system is at 3 kiloparsecs), which is far from the gravitational sphere of influence (about 100 parsecs for a black hole with mass one billion times that of the Sun).

Baby CareLink: development and implementation of a WWW-based system for neonatal home telemedicine.

Baby CareLink is a multifaceted telemedicine application designed to provide individualized information and support to families of Very Low Birth Weight infants. We believe that this innovative use of WWW and telemedicine technologies will improve family satisfaction and clinical care. In conjunction with improvements in family involvement, discharge planning, education, and follow-up enabled by other CareLink components, this system may allow infants to transition home even earlier in their hospital stay and thereby provide a clear cost savings.
