A 500 kpc HI Extension of the Virgo Pair NGC4532/DDO137 Detected by the Arecibo Legacy Fast ALFA (ALFALFA) Survey
R. A. Koopmann, R. Giovanelli, M. P. Haynes +6
We report the discovery of a ~500 kpc HI extension southwest of the Virgo Cluster HI-rich pair NGC 4532/DDO 137, detected as part of the Arecibo Legacy Fast ALFA (ALFALFA) Survey.…
Very Broad [O III]4959,5007 Emission from the NGC 4472 Globular Cluster RZ2109 and Implications for the Mass of Its Black Hole X-ray Source
Stephen E. Zepf, Daniel Stern, Thomas J. Maccarone +6
We present Keck LRIS spectroscopy of the black hole-hosting globular cluster RZ2109 in the Virgo elliptical galaxy NGC 4472. We find that this object has extraordinarily broad [OII…
[OIII] 5007 Emission from the Black-Hole X-ray Binary in a NGC 4472 Globular Cluster
Stephen E. Zepf, Thomas J. Maccarone, Gilles Bergond +3
We present the discovery of [OIII] 5007 emission associated with the black hole X-ray binary recently identified in a globular cluster in the Virgo elliptical galaxy NGC 4472. This…
