SS433 is the only Galactic binary system known to persistently accrete at highly super-critical (or hyper-critical) rates, similar to those in tidal disruption events, and likely n…
Improved Search for Solar Chameleons with a GridPix Detector at CAST
V. Anastassopoulos, S. Aune, K. Barth +66
We report on a new search for solar chameleons with the CERN Axion Solar Telescope (CAST). A GridPix detector was used to search for soft X-ray photons in the energy range from 200…
NuSTAR observations of Mrk 766: distinguishing reflection from absorption
D. J. K. Buisson, M. L. Parker, E. Kara +14
We present two new NuSTAR observations of the narrow line Seyfert 1 (NLS1) galaxy Mrk 766 and give constraints on the two scenarios previously proposed to explain its spectrum and…
