Deep Chandra observations of NGC 1404: cluster plasma physics revealed by an infalling early-type galaxy
Yuanyuan Su, Ralph P. Kraft, Elke Roediger +6
The intracluster medium (ICM), as a magnetized and highly ionized fluid, provides an ideal laboratory to study plasma physics under extreme conditions that cannot yet be achieved o…
Capturing the 3D Motion of an Infalling Galaxy via Fluid Dynamics
Yuanyuan Su, Ralph P. Kraft, Paul E. J. Nulsen +6
The Fornax Cluster is the nearest galaxy cluster in the southern sky. NGC 1404 is a bright elliptical galaxy falling through the intracluster medium of the Fornax Cluster. The shar…
A metric space for type Ia supernova spectra: a new method to assess explosion scenarios
Michele Sasdelli, W. Hillebrandt, M. Kromer +4
Over the past years type Ia supernovae (SNe Ia) have become a major tool to determine the expansion history of the Universe, and considerable attention has been given to, both, obs…
Search for transitions between states in redbacks and black widows using seven years of Fermi-LAT observations
Diego F. Torres, Long Ji, Jian Li +4
Considering about seven years of Fermi-Large Area Telescope (LAT) data, we present a systematic search for variability possibly related to transitions between states in redbacks an…
Optical photometry and spectroscopy of the low-luminosity, broad-lined Ic supernova iPTF15dld
E. Pian, L. Tomasella, E. Cappellaro +37
Core-collapse stripped-envelope supernova (SN) explosions reflect the diversity of physical parameters and evolutionary paths of their massive star progenitors. We have observed th…
Light-curve and spectral properties of ultra-stripped core-collapse supernovae leading to binary neutron stars
Takashi J. Moriya, Paolo A. Mazzali, Nozomu Tominaga +7
We investigate light-curve and spectral properties of ultra-stripped core-collapse supernovae. Ultra-stripped supernovae are the explosions of heavily stripped massive stars which…
Preheating of the early Universe by radiation from high-mass X-ray binaries
Sergey Sazonov, Ildar Khabibullin
Using a reliably measured intrinsic (i.e. corrected for absorption effects) present-day luminosity function of high-mass X-ray binaries (HMXBs) in the 0.25-2 keV energy band per un…
Bright end of the luminosity function of high-mass X-ray binaries: contributions of hard, soft and supersoft sources
Sergey Sazonov, Ildar Khabibullin
Using a spectral analysis of bright Chandra X-ray sources located in 27 nearby galaxies and maps of star-formation rate (SFR) and ISM surface densities for these galaxies, we const…
Polarization and long-term variability of Sgr A* X-ray echo
E. Churazov, I. Khabibullin, G. Ponti +1
We use a model of the molecular gas distribution within ~100 pc from the center of the Milky Way (Kruijssen, Dale & Longmore) to simulate time evolution and polarization properties…
Helium in Double-Detonation Models of Type Ia Supernovae
Aoife Boyle, Stuart A. Sim, Stephan Hachinger +1
The double-detonation explosion model has been considered a candidate for explaining astrophysical transients with a wide range of luminosities. In this model, a carbon-oxygen whit…
Neutron star kicks by the gravitational tug-boat mechanism in asymmetric supernova explosions: progenitor and explosion dependence
H. -Th. Janka
Asymmetric mass ejection in the early phase of supernova (SN) explosions can impart a kick velocity to the new-born neutron star (NS). For neutrino-driven explosions the NS acceler…
The outburst of the X-ray nova GRS 1739-278 in September, 2016
I. A. Mereminskiy, E. V. Filippova, R. A. Krivonos +3
During the scanning observations of the Galactic Center region in August - September 2016 we detected the new outburst of the historical X-ray nova GRS 1739-278, the black hole can…
Not that long time ago in the nearest galaxy: 3D slice of molecular gas revealed by a 110 years old flare of Sgr A*
E. Churazov, I. Khabibullin, R. Sunyaev +1
A powerful outburst of X-ray radiation from the supermassive black hole Sgr A* at the center of the Milky Way is believed to be responsible for the illumination of molecular clouds…
Type Ia supernovae within dense carbon-oxygen rich envelopes: a model for 'Super-Chandrasekhar' explosions?
U. M. Noebauer, S. Taubenberger, S. Blinnikov +2
We investigate the consequences of fairly normal Type Ia supernovae being embedded in compact and dense envelopes of carbon and oxygen rich circumstellar material by means of detai…
rHARM: Accretion and Ejection in Resistive GR-MHD
Qian Qian, Christian Fendt, Scott Noble +1
Turbulent magnetic diffusivity plays an important role for accretion disks and the launching of disk winds. We have implemented magnetic diffusivity, respective resistivity in the…
Fast evolving pair-instability supernova models: evolution, explosion, light curves
Alexandra Kozyreva, Matthew Gilmer, Raphael Hirschi +11
With an increasing number of superluminous supernovae (SLSNe) discovered the question of their origin remains open and causes heated debates in the supernova community. Currently,…
Magnetorotational instability in neutron star mergers: impact of neutrinos
Jerome Guilet, Andreas Bauswein, Oliver Just +1
The merger of two neutron stars may give birth to a long-lived hypermassive neutron star. If it harbours a strong magnetic field of magnetar strength, its spin-down could explain s…
Production and Distribution of Ti and Ni in a Three-dimensional Supernova Model Resembling Cassiopeia A
A. Wongwathanarat, H. -Th. Janka, E. Mueller +2
The spatial and velocity distributions of nuclear species synthesized in the innermost regions of core-collapse supernovae can yield important clues about explosion asymmetries and…
A dichotomy between the hard state spectral properties of black hole and neutron star X-ray~binaries
M. J. Burke, M. Gilfanov, R. Sunyaev
We analyse the spectra of black hole (BH) and neutron star (NS) X-ray binaries (XBs) in the hard state using archival RXTE observations. We find that there is a clear dichotomy in…
