Measuring the Coronal Properties of IC4329A with NuSTAR
L. W. Brenneman, G. Madejski, F. Fuerst +16
We present an analysis of a ~160 ks NuSTAR observation of the nearby bright Seyfert galaxy IC4329A. The high-quality broadband spectrum enables us to separate the effects of distan…
Inner Disc Obscuration in GRS 1915+105 Based on Relativistic Slim Disc Model
K. Vierdayanti, A. Sadowski, S. Mineshige +1
We study the observational signatures of the relativistic slim disc of 10 M_sun black hole, in a wide range of mass accretion rate, mdot, dimensionless spin parameter, a_ast, and v…
General Relativistic Magnetohydrodynamic Simulations of Blandford-Znajek Jets and the Membrane Paradigm
Robert F. Penna, Ramesh Narayan, Aleksander Sadowski
Recently it has been observed that the scaling of jet power with black hole spin in galactic X-ray binaries is consistent with the predictions of the Blandford-Znajek (BZ) jet mode…
An outburst scenario for the X-ray spectral variability in 3C 111
F. Tombesi, J. N. Reeves, C. S. Reynolds +2
We present a combined Suzaku and Swift BAT broad-band E=0.6-200keV spectral analysis of three 3C 111 observations obtained in 2010. The data are well described with an absorbed pow…
SN 2007uy - metamorphosis of an aspheric Type Ib explosion
Rupak Roy, Brijesh Kumar, Justyn R. Maund +13
The supernovae of Type Ibc are rare and the detailed characteristics of these explosions have been studied only for a few events. Unlike Type II SNe, the progenitors of Type Ibc ha…
Location of the bow shock ahead of cloud G2 at the Galactic Center
A. Sadowski, R. Narayan, L. Sironi +1
We perform detailed magnetohydrodynamic simulations of the gas cloud G2 interacting with the accretion flow around the Galactic Center black hole Sgr A*. We take as our initial con…
