Correlated Multi-Waveband Variability in the Blazar 3C~279 from 1996 to 2007
R. Chatterjee, S. G. Jorstad, A. P. Marscher +12
We present the results of extensive multi-waveband monitoring of the blazar 3C~279 between 1996 and 2007 at X-ray energies (2-10 keV), optical R band, and 14.5 GHz, as well as imag…
The Arecibo Legacy Fast ALFA Survey: VI. Second HI Source Catalog of the Virgo Cluster Region
Brian R. Kent, Riccardo Giovanelli, Martha P. Haynes +6
We present the third installment of HI sources extracted from the Arecibo Legacy Fast ALFA extragalactic survey. This dataset continues the work of the Virgo ALFALFA catalog. The c…
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.…
Optically Unseen HI Detections towards the Virgo Cluster detected in the Arecibo Legacy Fast ALFA Survey
Brian R. Kent, Riccardo Giovanelli, Martha P. Haynes +8
We report the discovery by the Arecibo Legacy Fast ALFA (ALFALFA) survey of eight HI features not coincident with stellar counterparts in the Virgo Cluster region. All of the HI cl…
The Multiple Timescales of Optical Variability of the Blazar 3C 279 During the 2001-2002 Outburst
Jeyhan S. Kartaltepe, Thomas J. Balonek
During 2001-2002 the optically violent variable (OVV) blazar 3C 279 un- derwent the most intense outburst seen during the entire fourteen year history that this quasar has been stu…
The Arecibo Legacy Fast ALFA Survey: III. HI Source Catalog of the Northern Virgo Cluster Region
R. Giovanelli, M. P. Haynes, B. R. Kent +20
We present the first installment of HI sources extracted from the Arecibo Legacy Fast ALFA (ALFALFA) extragalactic survey, initiated in 2005. Sources have been extracted from 3-D s…
