The Sleeping Monster: NuSTAR observations of SGR 1806-20, 11 years after the Giant Flare
George Younes, Matthew G. Baring, Chryssa Kouveliotou +5
We report the analysis of 5 NuSTAR observations of SGR 1806-20 spread over a year from April 2015 to April 2016, more than 11 years following its Giant Flare (GF) of 2004. The sour…
The Effect of Pair Cascades on the High-Energy Spectral Cutoff in Gamma-Ray Bursts
Ramandeep Gill, Jonathan Granot
The highly luminous and variable prompt emission in Gamma-Ray Bursts (GRBs) arises in an ultra-relativistic outflow. The exact underlying radiative mechanism shaping its non-therma…
The High Frequency Radio Emission of the Galactic Center Magnetar SGR J1745-29 During a Transitional Period
Joseph D. Gelfand, Scott Ransom, Chryssa Kouveliotou +6
The origin of the high-frequency radio emission detected from several magnetars is poorly understood. In this paper, we report the ~40 GHz properties of SGR J1745-29 as measured us…
Toward understanding the physical underpinnings of spatial and spectral morphologies of pulsar wind nebulae
Oleg Kargaltsev, Noel Klingler, Sarah Chastain +1
We discuss the observational properties of pulsar wind nebulae (PWNe) linking them to the injected (at the termination shock) electron spectral energy distribution and parameters o…
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…
Old but still warm: Far-UV detection of PSR B0950+08
G. G. Pavlov, B. Rangelov, O. Kargaltsev +3
We report on a Hubble Space Telescope detection of the nearby, old pulsar B0950+08 ( pc, spin-down age 17.5 Myr) in two far-ultraviolet (FUV) bands. We measured the me…
Spectroscopic identification of r-process nucleosynthesis in a double neutron star merger
E. Pian, P. D'Avanzo, S. Benetti +81
The merger of two neutron stars is predicted to give rise to three major detectable phenomena: a short burst of gamma-rays, a gravitational wave signal, and a transient optical/nea…
The unpolarized macronova associated with the gravitational wave event GW170817
S. Covino, K. Wiersema, Y. Z. Fan +37
The merger of two dense stellar remnants including at least one neutron star (NS) is predicted to produce gravitational waves (GWs) and short duration gamma ray bursts (GRBs). In t…
Illuminating Gravitational Waves: A Concordant Picture of Photons from a Neutron Star Merger
M. M. Kasliwal, E. Nakar, L. P. Singer +78
Merging neutron stars offer an exquisite laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an…
Strange matter prospects within the string-flip model
Niels-Uwe F. Bastian, David B. Blaschke, Mateusz Cierniak +4
In this contribution we extend the recently developed two-flavor quark-matter string-flip model by including strange quarks. We discuss implications for compact stars.
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Modeling the high-energy emission in GRB 110721A and implications on the early multiwavelength and polarimetric observations
N. Fraija, W. H. Lee, M. Araya +3
GRB 110721A was detected by the Gamma-ray Burst Monitor and the Large Area Telescope (LAT) onboard the Fermi satellite and the Gamma-ray Burst Polarimeter onboard the IKAROS solar…
The Arcminute Microkelvin Imager Catalogue of Gamma-ray Burst afterglows at 15.7 GHz
G. E. Anderson, T. D. Staley, A. J. van der Horst +7
We present the Arcminute Microkelvin Imager (AMI) Large Array catalogue of 139 gamma-ray bursts (GRBs). AMI observes at a central frequency of 15.7 GHz and is equipped with a fully…
Supernovae generated High Velocity Compact Clouds
Almog Yalinewich, Paz Beniamini
It has been proposed that an intermediate mass black hole can produce compact molecular clouds with large velocity dispersions. This model is called into question due to the discov…
Pulsar Wind Nebulae Created by Fast-Moving Pulsars
Oleg Kargaltsev, George G. Pavlov, Noel Klingler +1
We review multiwavelength properties of pulsar wind nebulae (PWNe) created by supersonically moving pulsars and the effects of pulsar motion on the PWN morphologies and the ambient…
Electrons' energy in GRB afterglows implied by radio peaks
Paz Beniamini, Alexander J. van der Horst
Gamma-ray burst (GRB) afterglows have been observed across the electromagnetic spectrum, and physical parameters of GRB jets and their surroundings have been derived using broadban…
Constraints on millisecond magnetars as the engines of prompt emission in gamma-ray bursts
Paz Beniamini, Dimitrios Giannios, Brian D. Metzger
We examine millisecond magnetars as central engines of Gamma Ray Bursts' (GRB) prompt emission. Using the proto-magnetar wind model of Metzger et al. 2011, we estimate the temporal…
