Is the `IR Coincidence' Just That?
Michael Nowak, Joern Wilms, Sebastian Heinz +3
(Abridged) Motch (1985) suggested that in the hard state of GX 339-4 the soft X-ray power-law extrapolated backward in energy agrees with the IR flux. Corbel & Fender (2002) showed…
Chandra Observations of the Interacting NGC 4410 Galaxy Group
Beverly J. Smith, Michael Nowak, Megan Donahue +1
We present high resolution X-ray imaging data from the ACIS-S instrument on the Chandra telescope of the nearby interacting galaxy group NGC 4410. Four galaxies in the inner portio…
Low Luminosity States of the Black Hole Candidate GX 339-4. I. ASCA and Simultaneous Radio/RXTE Observations
Joern Wilms, Michael Nowak, James B. Dove +2
We discuss a series of observations of the black hole candidate GX 339-4 in low luminosity, spectrally hard states. We present spectral analysis of three separate archival Advanced…
