A Possible Period for the K-Band Brightening Episodes of GX 17+2 (2009)
Bornak, Jillian, McNamara, Bernard J., Harrison, Thomas E., Rupen, Michael, Bandyopadhyay, Reba M., Wachter, Stefanie
The low-mass X-ray binary and Z source GX 17+2 undergoes infrared K-band brightening episodes of at least 3.5 mag. The source of these episodes is not known. Prior published K-band magnitudes and new...
The Fundamental Plane of Accretion Onto Black Holes with Dynamical Masses (2009)
Gultekin, Kayhan, Cackett, Edward M., Miller, Jon M., Di Matteo, Tiziana, Markoff, Sera, Richstone, Douglas O., ...
Black hole accretion and jet production are areas of intensive study in astrophysics. Recent work has found a relation between radio luminosity, X-ray luminosity, and black hole mass. With the...
The EVLA: prospects for HI (2008)
Ott, Jürgen, Perley, Rick, Rupen, Michael
To continue the unparalleled success of the Very Large Array (VLA) for radio astronomy, the facility is currently being converted to become the 'Expanded VLA' (EVLA). The EVLA will radically improve...
A transient radio jet in an erupting dwarf nova (2008)
Koerding, Elmar, Rupen, Michael, Knigge, Christian, Fender, Rob, Dhawan, Vivek, Templeton, Matthew, ...
Astrophysical jets seem to occur in nearly all types of accreting objects: from supermassive black holes to young stellar objects. Based on X-ray binaries, a unified scenario describing the disc/jet...
The EVLA: Prospects for HI (2008)
Ott, Juergen, Perley, Rick, Rupen, Michael, Team, The EVLA
To continue the unparalleled success of the Very Large Array (VLA) for radio astronomy, the facility is currently being converted to become the 'Expanded VLA' (EVLA). The EVLA will radically improve...
Long Term Spectral and Timing Behavior of the Black Hole Candidate XTE J1908+094 (2004)
Gogus, Ersin, Finger, Mark H., Kouveliotou, Chryssa, Woods, Peter M., Patel, Sandeep K., Rupen, Michael, ...
We present the long term X-ray light curves, detailed spectral and timing analyses of XTE J1908+094 using the Rossi X-ray Timing Explorer Proportional Counter Array observations covering two...
Cosmic Ray Acceleration by Stellar Associations? The Case of Cygnus OB2 (2003)
Butt, Yousaf, Benaglia, Paula, Combi, Jorge, Corcoran, Michael, Dame, Thomas, Drake, Jeremy, ...
The origins of all extra-solar cosmic rays -- both the ultra high-energy and lower energy Galactic variety -- remain unclear. It has been argued that the large scale shocks and turbulence induced by...
Disc-jet coupling in an atoll-type neutron star X-ray binary: 4U 1728-34 (GX 354-0) (2003)
Migliari, Simone, Fender, Rob, Rupen, Michael, Jonker, Peter, Klein-Wolt, Marc, Hjellming, Robert, ...
We have analysed 12 simultaneous radio (VLA) and X-ray (RXTE) observations of the atoll-type X-ray binary 4U 1728-34, performed in two blocks in 2000 and 2001. We have found that the strongest and...
CHANDRA/VLA Follow-up of TeV J2032+4131, the Only Unidentified TeV Gamma-ray Source (2003)
Butt, Yousaf, Benaglia, Paula, Combi, Jorge, Corcoran, Michael, Dame, Thomas, Drake, Jeremy, ...
The HEGRA Cherenkov telescope array group recently reported a steady and extended unidentified TeV gamma-ray source lying at the outskirts of Cygnus OB2. This is the most massive stellar association...
VLA detection of OH absorption from the elliptical galaxy NGC 1052 (2001)
Omar, Amitesh, Anantharamaiah, K. R., Rupen, Michael, Rigby, J.
VLA observations of OH absorption towards the elliptical galaxy NGC 1052 are presented. Both OH lines, at 1665 and 1667 MHz, were detected in absorption towards the center of NGC 1052. The hyperfine...
Images of an equatorial outflow in SS433 (2001)
Blundell, Katherine, Mioduszewski, Amy, Muxlow, Tom, Podsiadlowski, Philipp, Rupen, Michael
We have imaged the X-ray binary SS433 with unprecedented Fourier-plane coverage at 6cm using simultaneously the VLBA, MERLIN, and the VLA, and also at 20cm with the VLBA. At both wavelengths we have...
