Discovery of Radio Emission from the Quasar SDSS J1536+0441, a Candidate Binary Black-Hole System
J. M. Wrobel, A. Laor
The radio-quiet quasar SDSS J1536+0441 shows two broad-line emission systems that Boroson & Lauer interpret as a candidate binary black-hole system with a separation of 0.1 pc (0.0…

Motions of Galaxies in the Local Group and Beyond: an Astro2010 Science White Paper
M. J. Reid, A. Brunthaler, K. M. Menten +2
Recent advances with the VLBA have resulted in ~10 micro-arcsec astrometry for compact sources in external galaxies, and measurement of the proper motion of Local Group galaxies ha…
