A thin diffuse component of the Galactic Ridge X-ray emission and heating of the interstellar medium contributed by the radiation of Galactic X-ray binaries
Margherita Molaro, Rishi Khatri, Rashid Sunyaev
We predict a thin (scale height 80 pc) diffuse component of the Galactic Ridge X-ray emission (GRXE) arising from the scattering of the radiation of bright X-ray binaries (X…
Impact of thermal diffusion and other abundance anomalies on cosmological uses of galaxy clusters
P. Medvedev, M. Gilfanov, S. Sazonov +1
Depending on the topology of the magnetic field and characteristics of turbulent motions, diffusion can significantly affect the distribution of elements, in particular helium, in…
Type Ia Supernovae from Merging White Dwarfs I. Prompt Detonations
Rainer Moll, Cody Raskin, Daniel Kasen +1
Merging white dwarfs are a possible progenitor of Type Ia supernovae (SNe Ia). While it is not entirely clear if and when an explosion is triggered in such systems, numerical model…
Multi-Epoch High-Spectral-Resolution Observations of Neutral Sodium in 14 Type Ia Supernovae
A. Sternberg, A. Gal Yam, J. D. Simon +16
One of the main questions concerning Type Ia supernovae is the nature of the binary companion of the exploding white dwarf. A major discriminant between different suggested models…
SN 2010lp---a Type Ia supernova from a violent merger of two carbon--oxygen White Dwarfs
M. Kromer, R. Pakmor, S. Taubenberger +6
SN 2010lp is a subluminous Type Ia supernova (SN Ia) with slowly-evolving lightcurves. Moreover, it is the only subluminous SN Ia observed so far that shows narrow emission lines o…
On double-degenerate type Ia supernova progenitors as supersoft X-ray sources - A population synthesis analysis using SeBa
Mikkel T. B. Nielsen, Gijs Nelemans, Rasmus Voss +1
Context: The nature of the progenitors of type Ia supernova (SN) progenitors remains unclear. While it is usually agreed that single-degenerate progenitor systems would be luminous…
XIPE: the X-ray Imaging Polarimetry Explorer
Paolo Soffitta, Xavier Barcons, Ronaldo Bellazzini +96
X-ray polarimetry, sometimes alone, and sometimes coupled to spectral and temporal variability measurements and to imaging, allows a wealth of physical phenomena in astrophysics to…
Counting gamma rays in the directions of galaxy clusters
D. A. Prokhorov, E. M. Churazov
Emission of AGNs and neutral pion decay - are the two most natural mechanisms, that could make a galaxy cluster be a source of gamma-rays in the GeV regime. We revisited this probl…
Synthetic light curves and spectra for three-dimensional delayed-detonation models of Type Ia supernovae
S. A. Sim, I. R. Seitenzahl, M. Kromer +7
In a companion paper, Seitenzahl et al. (2013) presented a set of three-dimensional delayed detonation models for thermonuclear explosions of near-Chandrasekhar mass white dwarfs (…
Resonant scattering in the Perseus Cluster: spectral model for constraining gas motions with Astro-H
I. Zhuravleva, E. Churazov, R. Sunyaev +6
X-ray spectra from cores of galaxy clusters can be strongly distorted by resonant scattering of line photons, affecting metal abundance and gas velocity measurements. We introduce…
The Fast and Furious Decay of the Peculiar Type Ic Supernova 2005ek
M. R. Drout, A. M. Soderberg, P. A. Mazzali +21
We present extensive multi-wavelength observations of the extremely rapidly declining Type Ic supernova, SN 2005ek. Reaching a peak magnitude of M_R = -17.3 and decaying by ~3 mag…
A multi-wavelength investigation of the radio-loud supernova PTF11qcj and its circumstellar environment
A. Corsi, E. O. Ofek, A. Gal-Yam +20
We present the discovery, classification, and extensive panchromatic (from radio to X-ray) follow-up observations of PTF11qcj, a supernova discovered by the Palomar Transient Facto…
Nebular spectroscopy of the nearby type IIb supernova 2011dh
Isaac Shivvers, Paolo Mazzali, Jeffrey M. Silverman +6
We present nebular spectra of the nearby Type IIb supernova (SN) 2011dh taken between 201 and 678 days after core collapse. At these late times, SN 2011dh exhibits strong emission…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
GRB 081007 and GRB 090424: the surrounding medium, outflows and supernovae
Zhi-Ping Jin, Stefano Covino, Massimo Della Valle +34
We discuss the results of the analysis of multi-wavelength data for the afterglows of GRB 081007 and GRB 090424, two bursts detected by Swift. One of them, GRB 081007, also shows a…
Super Luminous Ic Supernovae: catching a magnetar by the tail

We report extensive observational data for five of the lowest redshift Super-Luminous Type Ic Supernovae (SL-SNe Ic) discovered to date, namely PTF10hgi, SN2011ke, PTF11rks, SN2011…
Combustion of a neutron star into a strange quark star: The neutrino signal
G. Pagliara, M. Herzog, F. K. Roepke
There are strong indications that the process of conversion of a neutron star into a strange quark star proceeds as a strong deflagration implying that in a few milliseconds almost…
Imprints of superfluidity on magneto-elastic QPOs of SGRs
