Simultaneous Radio and Optical Polarimetry of GRB 191221B Afterglow
Yuji Urata, Kenji Toma, Stefano Covino +16
Gamma-ray bursts (GRBs) are the most luminous transients in the universe and are utilized as probes of early stars, gravitational wave counterparts, and collisionless shock physics…
Particle acceleration controlled by ambient density in the southwestern rim of RCW 86
Hiromasa Suzuki, Satoru Katsuda, Takaaki Tanaka +3
Particle acceleration physics at supernova remnant (SNR) shocks is one of the most intriguing problems in astrophysics. SNR RCW~86 provides a suitable environment for understanding…
Deciphering the extreme X-ray variability of the nuclear transient eRASSt J045650.3-203750: A likely repeating partial tidal disruption event
Zhu Liu, A. Malyali, M. Krumpe +17
(Abridged) In this paper, we present the results of an exceptional repeating X-ray nuclear transient, eRASSt J045650.3-203750 (hereafter J0456-20), uncovered by SRG/eROSITA in a qu…
Spectral Break of Energetic Pulsar Wind Nebulae Detected with Wideband X-ray Observations
Aya Bamba, Shinpei Shibata, Shuta J. Tanaka +4
Pulsar wind nebulae (PWNe) are one of the most energetic galactic sources with bright emissions from radio waves to very high-energy gamma-rays. We perform wideband X-ray spectrosc…
A spatially resolved study of hard X-ray emission in Kepler's SNR: indications of different regimes of particle acceleration
Vincenzo Sapienza, Marco Miceli, Aya Bamba +6
Synchrotron X-ray emission in young supernova remnants (SNRs) is a powerful diagnostic tool to study the population of high energy electrons accelerated at the shock front and the…
Gamma-ray Diagnostics of r-process Nucleosynthesis in the Remnants of Galactic Binary Neutron-Star Mergers
Yukikatsu Terada, Yuya Miwa, Hayato Ohsumi +4
We perform a full nuclear-network numerical calculation of the -process nuclei in binary neutron-star mergers (NSMs), with the aim of estimating -ray emissions from the remna…
discovery of far-infrared emission from the hot spot D in the radio galaxy Cygnus A
Yuji Sunada, Naoki Isobe, Makoto S. Tashiro +3
The far infrared counterpart of hot spot D, the terminal hot spot of the eastern jet hosted by the radio galaxy Cygnus A, is detected with \textit{Herschel} Aperture photometery of…
The Second Catalog of Interplanetary Network Localizations of Konus Short Duration Gamma-Ray Bursts
D. Svinkin, K. Hurley, A. Ridnaia +72
We present the catalog of Interplanetary Network (IPN) localizations for 199 short-duration gamma-ray bursts (sGRBs) detected by the Konus-Wind (KW) experiment between 2011 January…
NuSTAR discovery of the hard X-ray emission and a wide-band X-ray spectrum from the Pictor A western hot spot
Yuji Sunada, Arisa Morimoto, Makoto S. Tashiro +5
Utilizing \textit{Chandra}, \textit{XMM-Newton} and \textit{NuSTAR}, a wide-band X-ray spectrum through 0.2 to 20 keV is reported from the western hot spot of Pictor A. In particul…
X-ray Line Diagnostics of Ion Temperature at Cosmic-Ray Accelerating Collisionless Shocks
Jiro Shimoda, Yutaka Ohira, Aya Bamba +4
A novel collisionless shock jump condition is suggested by modeling the entropy production at the shock transition region. We also calculate downstream developments of the atomic i…
Search for Spatial Correlations of Neutrinos with Ultra-High-Energy Cosmic Rays
The ANTARES collaboration, A. Albert, S. Alves +1042
For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of high-energy astrophysics. One approach for solving this puzzle is to corr…
