The Crab nebula variability at short timescales with the Cherenkov Telescope Array
Enrique Mestre, Emma de Ona Wilhelmi, Dmitry Khangulyan +3
Since 2009, several rapid and bright flares have been observed at high energies (>100 MeV) from the direction of the Crab Nebula. Several hypotheses have been put forward to explai…
Sign of hard X-ray pulsation from the gamma-ray binary system LS 5039
Hiroki Yoneda, Kazuo Makishima, Teruaki Enoto +3
To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectiv…
Physical Conditions and Particle Acceleration in the Kiloparsec Jet of Centaurus A
Takahiro Sudoh, Dmitry Khangulyan, Yoshiyuki Inoue
The non-thermal emission from the kiloparsec-scale jet of Centaurus A exhibits two notable features, bright diffuse emission and many compact knots, which have been intensively stu…
Detection of Small Flares from the Crab Nebula with Fermi-LAT
Masanori Arakawa, Masaaki Hayashida, Dmitry Khangulyan +1
Gamma radiation from the Crab pulsar wind nebula (PWN) shows significant variability at MeV energies, recently revealed with spaceborne gamma-ray telescopes. Here we repo…
Fast moving pulsars as probes of interstellar medium
Maxim Barkov, Maxim Lyutikov, Dmitry Khangulyan
Pulsars moving through ISM produce bow shocks detected in hydrogen H line emission. The morphology of the bow shock nebulae allows one to probe the properties of ISM on scales $…
