Ultraviolet Spectroscopy of Type IIb Supernovae: Diversity and the Impact of Circumstellar Material
Sagi Ben-Ami, Stephan Hachinger, Avishay Gal-Yam +9
We present new Hubble Space Telescope (HST) multi-epoch ultraviolet (UV) spectra of the bright Type IIb SN 2013df, and undertake a comprehensive anal- ysis of the set of four Type…
5.9 keV Mn K-shell X-ray luminosity from the decay of 55Fe in Type Ia supernova models
I. R. Seitenzahl, A. Summa, F. Krauss +12
We show that the X-ray line flux of the Mn Kalpha line at 5.9 keV from the decay of 55Fe is a promising diagnostic to distinguish between Type Ia supernova (SN Ia) explosion models…
Oxygen emission in remnants of thermonuclear supernovae as a probe for their progenitor system
D. Kosenko, W. Hillebrandt, M. Kromer +3
Recent progress in numerical simulations of thermonuclear supernova explosions brings up a unique opportunity in studying the progenitors of Type Ia supernovae. Coupling state-of-t…
Optical Synchrotron Precursors of Radio Hypernovae
Daisuke Nakauchi, Kazumi Kashiyama, Hiroki Nagakura +2
We examine the bright radio synchrotron counterparts of low-luminosity gamma-ray bursts (llGRBs) and relativistic supernovae (SNe) and find that they can be powered by spherical hy…
Searching for coherent pulsations in ultraluminous X-ray sources
V. Doroshenko, A. Santangelo, L. Ducci
Luminosities of ultraluminous X-ray sources (ULXs) are uncomfortably large if compared to the Eddington limit for isotropic accretion onto stellar-mass object. Most often either su…
Turbulent Heating in Galaxy Clusters Brightest in X-rays
I. Zhuravleva, E. Churazov, A. A. Schekochihin +9
The hot, X-ray-emitting intracluster medium (ICM) is the dominant baryonic constituent of clusters of galaxies. In the cores of many clusters, radiative energy losses from the ICM…
Type Ia Supernova Spectral Features in the Context of Their Host Galaxy Properties
Y. -C. Pan, M. Sullivan, K. Maguire +5
We analyse spectroscopic measurements of 122 type Ia supernovae (SNe Ia) with z<0.09 discovered by the Palomar Transient Factory, focusing on the properties of the Si II 6355 and C…
Shaping the X-ray spectrum of galaxy clusters with AGN feedback and turbulence
M. Gaspari
The hot plasma filling galaxy clusters emits copious X-ray radiation. The classic unheated and unperturbed cooling flow model predicts dramatic cooling rates and an isobaric X-ray…
The Denoised, Deconvolved, and Decomposed Fermi -ray sky - An application of the DPO algorithm
Marco Selig, Valentina Vacca, Niels Oppermann +1
We analyze the 6.5yr all-sky data from the Fermi LAT restricted to gamma-ray photons with energies between 0.6-307.2GeV. Raw count maps show a superposition of diffuse and point-li…
Probing Rotation of Core-collapse Supernova with Concurrent Analysis of Gravitational Waves and Neutrinos
Takaaki Yokozawa, Mitsuhiro Asano, Tsubasa Kayano +4
The next time a core-collapse supernova (SN) explodes in our galaxy, vari- ous detectors will be ready and waiting to detect its emissions of gravitational waves (GWs) and neutrino…
Neutrino viscosity and drag: impact on the magnetorotational instability in protoneutron stars
Jerome Guilet, Ewald Mueller, Hans-Thomas Janka
The magnetorotational instability (MRI) is a promising mechanism to amplify the magnetic field in fast rotating protoneutron stars. The diffusion of neutrinos trapped in the PNS in…
Hard X-ray emission of Sco X-1
Mikhail G. Revnivtsev, Sergey S. Tsygankov, Eugene M. Churazov +1
We study hard X-ray emission of the brightest accreting neutron star Sco X-1 with INTEGRAL observatory. Up to now INTEGRAL have collected ~4 Msec of deadtime corrected exposure on…
On the nuclear robustness of the r process in neutron-star mergers
Joel de Jesús Mendoza-Temis, Meng-Ru Wu, Karlheinz Langanke +3
We have performed r-process calculations for matter ejected dynamically in neutron star mergers based on a complete set of trajectories from a three-dimensional relativistic smooth…
The Vela Pulsar With an Active Fallback Disk
Gökçe Özsükan, K. Yavuz Ekşi, Valeri Hambaryan +4
Fallback disks are expected to form around young neutron stars. The presence of these disks can be revealed by their blackbody spectrum in the infrared, optical and UV bands. We pr…
SN2014J gamma-rays from the 56Ni decay chain
Roland Diehl, Thomas Siegert, Wolfgang Hillebrandt +7
The measurement of gamma-ray lines from the decay chain of 56Ni provides unique information about the explosion in supernovae. The 56Ni freshly-produced in the supernova powers the…
Three-Dimensional Simulations of Core-Collapse Supernovae: From Shock Revival to Shock Breakout
Annop Wongwathanarat, Ewald Mueller, H. -Thomas Janka
We present 3D simulations of core-collapse supernovae from blast-wave initiation by the neutrino-driven mechanism to shock breakout from the stellar surface, considering two 15 Msu…
The ejected mass distribution of type Ia supernovae: A significant rate of non-Chandrasekhar-mass progenitors
R. A. Scalzo, A. J. Ruiter, S. A. Sim
The ejected mass distribution of type Ia supernovae directly probes progenitor evolutionary history and explosion mechanisms, with implications for their use as cosmological probes…
