Studying the Ultraviolet Spectrum of the First Spectroscopically Confirmed Supernova at redshift two
M. Smith, M. Sullivan, R. C. Nichol +87
We present observations of DES16C2nm, the first spectroscopically confirmed hydrogen-free superluminous supernova (SLSN-I) at redshift z~2. DES16C2nm was discovered by the Dark Ene…
Evidence for Dynamically Driven Formation of the GW170817 Neutron Star Binary in NGC 4993
A. Palmese, W. Hartley, F. Tarsitano +89
We present a study of NGC 4993, the host galaxy of the GW170817 gravitational wave event, the GRB170817A short gamma-ray burst (sGRB) and the AT2017gfo kilonova. We use Dark Energy…
Ultra-High Energy Cosmic Rays and Neutrinos from Tidal Disruptions by Massive Black Holes
Claire Guépin, Kumiko Kotera, Enrico Barausse +2
Tidal disruptions are extremely powerful phenomena that have been designated as candidate sources of ultra-high-energy cosmic rays. The disruption of a star by a black hole can nat…
Retainment of r-process material in dwarf galaxies
Paz Beniamini, Irina Dvorkin, Joe Silk
The synthesis of -process elements is known to involve extremely energetic explosions. At the same time, recent observations find significant -process enrichment even in extr…
Fermionic Light Dark Matter particles and the New Physics of Neutron Stars
M. Cermeño, M. Ángeles Pérez-García, Joseph Silk
Dark Matter constitutes most of the matter in the presently accepted cosmological model for our Universe. The extreme conditions of ordinary baryonic matter, namely high density an…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
S. J. Smartt, T. -W. Chen, A. Jerkstrand +118
Gravitational waves were discovered with the detection of binary black hole mergers and they should also be detectable from lower mass neutron star mergers. These are predicted to…
The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/VIRGO GW170817. II. UV, Optical, and Near-IR Light Curves and Comparison to Kilonova Models
P. S. Cowperthwaite, E. Berger, V. A. Villar +141
We present UV, optical, and NIR photometry of the first electromagnetic counterpart to a gravitational wave source from Advanced LIGO/Virgo, the binary neutron star merger GW170817…
The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/Virgo GW170817. I. Dark Energy Camera Discovery of the Optical Counterpart
M. Soares-Santos, D. E. Holz, J. Annis +142
We present the Dark Energy Camera (DECam) discovery of the optical counterpart of the first binary neutron star merger detected through gravitational wave emission, GW170817. Our o…
Relativistic magnetohydrodynamical simulations of the resonant corrugation of a fast shock front
Camilia Demidem, Martin Lemoine, Fabien Casse
The generation of turbulence at magnetized shocks and its subsequent interaction with the latter is a key question of plasma- and high-energy astrophysics. This paper presents two-…
Exploring stellar evolution with gravitational-wave observations
Irina Dvorkin, Jean-Philippe Uzan, Elisabeth Vangioni +1
Recent detections of gravitational waves from merging binary black holes opened new possibilities to study the evolution of massive stars and black hole formation. In particular, s…
Dark matter line searches towards dwarf galaxies with H.E.S.S
Louise Oakes, Aion Viana, Emmanuel Moulin +7
High energy -rays are powerful probes in the search for annihilations of dark matter (DM) par- ticles in dense environments. In several DM particle models their annihilation pro…
Search for gamma-ray emission from super-luminous supernovae with the Fermi-LAT
Nicolas Renault-Tinacci, Kumiko Kotera, Andrii Neronov +1
We present the first individual and stacking systematic search for -ray emission in the GeV band with the {\it Fermi} Large Area Telescope (LAT), in the directions of 45 super-l…
LSQ14efd: observations of the cooling of a shock break-out event in a type Ic Supernova
C. Barbarino, M. T. Botticella, M. Dall'Ora +29
We present the photometric and spectroscopic evolution of the type Ic supernova LSQ14efd, discovered by the La Silla QUEST survey and followed by PESSTO. LSQ14efd was discovered fe…
The host galaxy of the short GRB111117A at : impact on the short GRB redshift distribution and progenitor channels
J. Selsing, T. Krühler, D. Malesani +26
It is notoriously difficult to localize short -ray bursts (sGRBs) and their hosts to measure their redshifts. These measurements, however, are critical to constrain the nature o…
Multi-epoch intra-night optical monitoring of 8 radio-quiet BL Lac candidates
P. Kumar, Gopal-Krishna, C. S. Stalin +3
For a new sample of 8 weak-line-quasars (WLQs) we report a sensitive search in 20 intranight monitoring sessions, for blazar-like optical flux variations on hour-like and longer ti…
The evolutionary roads leading to low effective spins, high black hole masses, and O1/O2 rates of LIGO/Virgo binary black holes
K. Belczynski, J. Klencki, C. E. Fields +31
All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported from the O1/O2 runs have near zero effective spins. There are only three potential explanations of this fact. If…
Towards understanding the physics of collisionless relativistic shocks
Guy Pelletier, Andrei Bykov, Don Ellison +1
Relativistic astrophysical collisionless shocks represent outstanding dissipation agents of the huge power of relativistic outflows produced by accreting black holes, core collapse…
What can we learn from "internal plateaus"? The peculiar afterglow of GRB 070110
Paz Beniamini, Robert Mochkovitch
Context: The origin of GRBs' prompt emission is highly debated. Proposed scenarios involve dissipation processes above or below the photosphere of an ultra-relativistic outflow. Ai…
Time evolution of the spectral break in the high-energy extra component of GRB 090926A
M. Yassine, F. Piron, R. Mochkovitch +1
We report on a new time-resolved analysis of the GRB 090926A broad-band spectrum during its prompt phase, and on its interpretation in the framework of prompt emission models. We c…
The origin of the Ultraluminous X-ray Sources
Grzegorz Wiktorowicz, Małgorzata Sobolewska, Jean-Pierre Lasota +1
Recently, several ultraluminous X-ray (ULX) sources were shown to host a neutron star (NS) accretor. We perform a suite of evolutionary calculations which show that, in fact, NSs a…
