A precise measurement of the orbital period parameters of Cygnus X-3
Yash Bhargava, A. R. Rao, K. P. Singh +9
We present X-ray light curves of Cygnus X-3 as measured by the recently launched AstroSat satellite. The light curve folded over the binary period of 4.8 hours shows a remarkable s…
Searching for highly obscured AGN in the XMM-Newton serendipitous source catalog
A. Corral, I. Georgantopoulos, M. G. Watson +9
The majority of active galactic nuclei (AGN) are obscured by large amounts of absorbing material that makes them invisible at many wavelengths. X-rays, given their penetrating powe…
Do the spectral energy distributions of type 1 AGN show diversity?
A. E. Scott, G. C. Stewart
We create broadband SEDs of 761 type 1 AGN. The Scott et al. sample, created by a cross-correlation of the optical SDSS DR5 quasar catalogue and the 2XMMi catalogue of serendipitou…
X-ray absorption evolution in Gamma-Ray Bursts: intergalactic medium or evolutionary signature of their host galaxies?
R. L. C. Starling, R. Willingale, N. R. Tanvir +5
The intrinsic X-ray emission of Gamma-Ray Bursts (GRBs) is often found to be absorbed over and above the column density through our own galaxy. The extra component is usually assum…
Detectability of low energy X-ray spectral components in type 1 AGN
A. E. Scott, G. C. Stewart, S. Mateos
In this paper we examine the percentage of type 1 AGN which require the inclusion of a soft excess component and/or significant cold absorption in the modelling of their X-ray spec…
New constraints on the X-ray spectral properties of type 1 AGN
A. E. Scott, G. C. Stewart, S. Mateos +3
We present a detailed characterization of the X-ray spectral properties of 761 type 1 AGN, selected from a cross-correlation of the SDSS DR5 quasar catalogue and the incremental ve…
