GALI -- A GAmma-ray burst Localizing Instrument: Results from Full Size Engineering Model
Julia Saleh-Natur, Ehud Behar, Omer Reich +9
We present a full-size engineering model of GALI - The GAmma-ray burst Localizing Instrument, composed of 362 CsI(Tl) small cubic scintillators, distributed within a small volume o…
A NICER viewing angle on the accretion stream of Vela X-1
Roi Rahin, Ehud Behar
Vela X-1 is the archetypical eclipsing high-mass X-ray binary, composed of a neutron star (NS) accreting the B-star wind. It was observed by nearly all X-ray observatories, often m…
Shocks in the outflow of the RS Oph 2021 eruption observed with X-ray gratings
Marina Orio, Ehud Behar, Juan Luna +9
The 2021 outburst of the symbiotic recurrent nova RS Oph was observed with the Chandra High Energy Transmission Gratings (HETG) on day 18 after optical maximum and with XMM-Newton…
GALI: a Gamma-ray Burst Localizing Instrument
Roi Rahin, Luca Moleri, Alex Vdovin +6
The detection of astrophysical Gamma-Ray Bursts (GRBs) has always been intertwined with the challenge of identifying the direction of the source. Accurate angular localization of b…
Canonical X-Ray Fluorescence Line Intensities as Column Density Indicators
Roi Rahin, Ehud Behar
X-ray line fluorescence is ubiquitous around powerful accretion sources, namely active galactic nuclei and X-ray binaries. The brightest and best-studied line is the Fe K line a…
Cosmological evolution of the absorption of -ray burst X-ray afterglows
Roi Rahin, Ehud Behar
X-ray absorption of -ray burst (GRB) afterglows is prevalent yet poorly understood. X-ray derived neutral hydrogen column densities () of GRB X-ray afterglows show an…
Constraining the Fraction of Core-Collapse Supernovae Harboring Choked Jets with High-energy Neutrinos
Dafne Guetta, Roi Rahin, Imre Bartos +1
The joint observation of core-collapse supernovae with gamma-ray bursts shows that jets can be launched in the aftermath of stellar core collapse, likely by a newly formed black ho…
Comparing shocks in planetary nebulae with the solar wind termination shock
Noam Soker, Roi Rahin, Ehud Behar +1
We show that suprathermal particles, termed pick-up ions (PUIs), might reduce the postshock temperature of the fast wind and jets in some planetary nebulae (PNs) and in symbiotic s…
