Electron Firehose Instabilities in High- ICM shocks
Sunjung Kim, Ji-Hoon Ha, Dongsu Ryu +1
The preacceleration of electrons through reflection and shock drift acceleration (SDA) is essential for the diffusive shock acceleration (DSA) of nonthermal electrons in collisionl…
Investigation of X-ray timing and spectral properties of ESO 243-49 HLX-1 with long-term Swift Monitoring
Lupin Chun-Che Lin, Chin-Ping Hu, Kwan-Lok Li +5
The long-term Swift monitoring of ESO 243-49 HLX-1 provides an opportunity to investigate the detailed timing and spectral behaviour of this hyper-luminous X-ray source. Swift has…
Chandra Observations of the Spectacular A3411-12 Merger Event
Felipe Andrade-Santos, Reinout J. van Weeren, Gabriella Di Gennaro +17
We present deep Chandra observations of A3411-12, a remarkable merging cluster that hosts the most compelling evidence for electron re-acceleration at cluster shocks to date. Using…
Gamma-ray and Neutrino Emissions due to Cosmic-Ray Protons Accelerated at Intracluster Shocks in Galaxy Clusters
Ji-Hoon Ha, Dongsu Ryu, Hyesung Kang
We examine the cosmic-ray protons (CRp) accelerated at collisionless shocks in galaxy clusters using cosmological structure formation simulations. We find that in the intracluster…
Three-dimensional simulations of non-resonant streaming instability and particle acceleration near non-relativistic astrophysical shocks
Allard Jan van Marle, Fabien Casse, Alexandre Marcowith
We use particle-in-magnetohydrodynamics-cells to model particle acceleration and magnetic field amplification in a high Mach, parallel shock in three dimensions and compare the res…
An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the First and Second Observing Runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1195
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the…
Search for Eccentric Binary Black Hole Mergers with Advanced LIGO and Advanced Virgo during their First and Second Observing Runs
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1183
When formed through dynamical interactions, stellar-mass binary black holes may retain eccentric orbits ( at 10 Hz) detectable by ground-based gravitational-wave detectors.…
X-Ray spectral evolution of PSR~J2032+4127 during the 2017 periastron passage
Partha Sarathi Pal, P. H. Thomas Tam, Yudong Cui +3
We report X-ray data analysis results obtained from Chandra, XMM-Newton, NuSTAR and Swift observations of PSR J2032+4127 taken before, during, and after the periastron on 2017 Nove…
Search for gravitational-wave signals associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo
B. P. Abbott, R. Abbott, T. D. Abbott +1196
We present the results of targeted searches for gravitational-wave transients associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo,…
Shock acceleration efficiency in radio relics
A. Botteon, G. Brunetti, D. Ryu +1
Radio relics in galaxy clusters are giant diffuse synchrotron sources powered in cluster outskirts by merger shocks. Although the relic-shock connection has been consolidated in re…
Turbulence Dynamo in Galaxy Clusters
Soonyoung Roh, Dongsu Ryu, Hyesung Kang +2
The existence of microgauss magnetic fields in galaxy clusters have been established through observations of synchrotron radiation and Faraday rotation. They are conjectured to be…
A Diffusive Shock Acceleration Model for Protons in Weak Quasi-parallel Intracluster Shocks
Dongsu Ryu, Hyesung Kang, Ji-Hoon Ha
Low sonic Mach number shocks form in the intracluster medium (ICM) during the formation of the large-scale structure of the universe. Nonthermal cosmic-ray (CR) protons are expecte…
