Soft-excess in ULX spectra: disc emission or wind absorption?
A. C. Goncalves, R. Soria
We assess the claim that Ultra-luminous X-ray sources (ULXs) host intermediate-mass black holes (BH) by comparing the cool disc-blackbody model with a range of other models, namell…
Modelling mid-Z element atmospheres for strongly-magnetized neutron stars
Kaya Mori, Wynn C. G. Ho
We construct models for strongly-magnetized neutron star atmospheres composed of mid-Z elements (carbon, oxygen and neon) with magnetic fields B=10^{12}-10^{13} G and effective tem…
The Interstellar Medium of GRB Host Galaxies I. Echelle Spectra of Swift GRB Afterglows
J. X. Prochaska, H. -W. Chen, J. S. Bloom +8
We present optical echelle spectra of four gamma-ray burst (GRB) afterglows (GRB 050730, GRB 050820, GRB 051111, and GRB 060418) discovered during the first 1.5 years of operation…
Recent observational progress in AM CVn binaries
G. Ramsay, C. Brocksopp, P. Groot +9
We present the results of some recent research on AM CVn systems. We present: X-ray/UV observations made using XMM-Newton; the X-ray grating spectrum of RX J1914+24; preliminary re…
A Compact Supermassive Binary Black Hole System
C. Rodriguez, G. B. Taylor, R. T. Zavala +3
We report on the discovery of a supermassive binary black hole system in the radio galaxy 0402+379, with a projected separation between the two black holes of just 7.3 pc. This is…
Infrared SEDs of Seyfert Galaxies: Starbursts and the Nature of the Obscuring Medium
Catherine L. Buchanan, Jack F. Gallimore, Christopher P. O'Dea +5
We present the results of IRS low-resolution spectroscopy of 51 Seyfert galaxies, part of a large Spitzer observing program to determine the mid-to-far infrared spectral energy dis…
