Unification of X-ray winds in Seyfert galaxies: from ultra-fast outflows to warm absorbers
F. Tombesi, M. Cappi, J. N. Reeves +4
The existence of ionized X-ray absorbing layers of gas along the line of sight to the nuclei of Seyfert galaxies is a well established observational fact. This material is systemat…
3D deflagration simulations leaving bound remnants: a model for 2002cx-like Type Ia supernovae
M. Kromer, M. Fink, V. Stanishev +10
2002cx-like supernovae are a sub-class of sub-luminous Type Ia supernovae. Their light curves and spectra are characterized by distinct features that indicate strong mixing of the…
Multiwavelength study of the newly confirmed supernova remnant MCSNR J0527-7104 in the Large Magellanic Cloud
Patrick J. Kavanagh, Manami Sasaki, Sean D. Points +6
The Large Magellanic Cloud (LMC) hosts a rich and varied population of supernova remnants (SNRs). Optical, X-ray, and radio observations are required to identify these SNRs, as wel…
Hard X-ray emission lines from the decay of Ti-44 in the remnant of supernova 1987A
S. A. Grebenev, A. A. Lutovinov, S. S. Tsygankov +1
It is assumed that the radioactive decay of Ti-44 powers the infrared, optical and UV emission of supernova remnants after the complete decay of Co-56 and Co-57 (the isotopes that…
LMXB populations in galaxy outskirts: globular clusters and supernova kicks
Zhongli Zhang, Marat Gilfanov, Akos Bogdan
For the first time, we have systematically explored the population of discrete X-ray sources in the outskirts of early-type galaxies. Based on a broad sample of 20 galaxies observe…
Reconnection-driven plasmoids in blazars: fast flares on a slow envelope
Dimitrios Giannios
Minute-timescale TeV flares have been observed in several blazars. The fast flaring requires compact regions in the jet that boost their emission towards the observer at an extreme…
Quantifying properties of ICM inhomogeneities
I. Zhuravleva, E. Churazov, A. Kravtsov +3
We present a new method to identify and characterize the structure of the intracluster medium (ICM) in simulated galaxy clusters. The method uses the median of gas properties, such…
Supergiant, fast, but not so transient 4U 1907+09
V. Doroshenko, A. Santangelo, L. Ducci +1
We have investigated the dipping activity observed in the high-mass X-ray binary 4U 1907+09 and shown that the source continues to pulsate in the "off" state, noting that the trans…
Shearing box simulations of accretion disk winds
R. Moll
The launching process of a magnetically driven outflow from an accretion disk is investigated in a local, shearing box model which allows a study of the feedback between accretion…
Three-dimensional neutrino-driven supernovae: Neutron star kicks, spins, and asymmetric ejection of nucleosynthesis products
A. Wongwathanarat, H. -Th. Janka, E. Mueller
We present 3D simulations of supernova (SN) explosions of nonrotating stars, triggered by the neutrino-heating mechanism with a suitable choice of the core-neutrino luminosity. Our…
XMM-Newton view of the N 206 superbubble in the Large Magellanic Cloud
Patrick J. Kavanagh, Manami Sasaki, Sean. D. Points
We perform an analysis of the X-ray superbubble in the N 206 HII region in the Large Magellanic Cloud using current generation facilities to gain a better understanding of the phys…
A theoretical color-velocity correlation for supernovae associated with gamma-ray bursts
Sharon Rapoport, Stuart A. Sim, Keiichi Maeda +4
We carry out the first multi-dimensional radiative transfer calculations to simultaneously compute synthetic spectra and light curves for models of supernovae driven by fast bipola…
Accurate Localization and Identification of Six Hard X-ray Sources from Chandra and XMM-Newton data
D. I. Karasev, A. A. Lutovinov, M. G. Revnivtsev +1
We present the results of Chandra and XMM-Newton observations for six hard X-ray sources (IGR J12134-6015, IGR J18293-1213, IGR J18219-1347, IGR J17350-2045, IGR J18048-1455, XTE J…
The high-field polar RX J1007.5-2017
H. -C. Thomas, K. Beuermann, K. Reinsch +2
We report optical and X-ray observations of the high-field polar RXJ1007.5-2017 performed between 1990 and 2012. It has an orbital period of 208.60 min determined from the ellipsoi…
Interpreting the near-infrared spectra of the 'golden standard' Type Ia supernova 2005cf
E. E. E. Gall, S. Taubenberger, M. Kromer +5
We present nine near-infrared (NIR) spectra of supernova (SN) 2005cf at epochs from -10 d to +42 d with respect to B-band maximum, complementing the existing excellent data sets av…
Contribution of the accretion disk, hot corona, and obscuring torus to the luminosity of Seyfert galaxies: INTEGRAL and Spitzer observations
S. Sazonov, S. P. Willner, A. D. Goulding +12
We estimate the relative contributions of the supermassive black hole (SMBH) accretion disk, corona, and obscuring torus to the bolometric luminosity of Seyfert galaxies, using Spi…
