Multiwavelength Observations and State Transitions of an Ultra-luminous Supersoft X-ray Source: Evidence for an Intermediate-Mass Black Hole
A. K. H. Kong, M. P. Rupen, L. O. Sjouwerman +1
We report the results of Chandra and XMM-Newton observations of an ultra-luminous supersoft X-ray source in M101. M101 ULX-1 underwent 2 outbursts in 2004 during which the peak bol…
Cosmic Ray Acceleration by Stellar Associations? The Case of Cygnus OB2
Yousaf Butt, Paula Benaglia, Jorge Combi +10
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 tur…
Post-outburst radio spectral evolution of Cygnus X-3
James CA Miller-Jones, Katherine M Blundell, Michael P Rupen +2
Multifrequency VLA and OVRO observations of the radio outburst of Cygnus X-3 in September 2001 are presented, illustrating the evolution of the spectrum of the source over a period…
The ruff of equatorial emission around the SS433 jets: its spectral index and origin
Katherine M Blundell, Michael P Rupen, Amy J Mioduszewski +2
We present unique radio observations of SS433, using MERLIN, the VLBA, and the VLA, which allow us to, for the first time, properly image and derive a meaningful spectral index for…
An HI Rogues Gallery
J. E. Hibbard, J. H. van Gorkom, M. P. Rupen +1
We have begun a compilation of HI maps of peculiar galaxies kindly contributed by individual investigators, many as part of the ``Gas & Galaxy Evolution'' conference. In this galle…
HI in Early-Type Galaxies
T. Oosterloo, R. Morganti, E. M. Sadler
We briefly discuss the main differences between the HI properties of luminous and low-luminosity early-type galaxies. In luminous early-type galaxies the HI is often irregularly di…
