Acceleration of solar wind particles by traveling interplanetary shocks
(IOP Publishing, 2019)The acceleration of thermal solar wind (SW) protons at spherical interplanetary shocks driven by coronal mass ejections is investigated. The SW velocity distribution is represented using κ-functions, which are transformed ... -
Are anomalous cosmic rays the main contribution to the low-energy galactic cosmic ray spectrum?
(IOP Publishing, 2008)While the high-energy part of the Galactic cosmic ray spectrum is well observed, its nature at energies below about 1 GeV nucleon-1 is still not known well. Recent in situ measurements made with the Voyager 1 spacecraft in ... -
H.E.S.S. and Fermi-LAT observations of PSR B1259-63/LS 2883 during its 2014 and 2017 periastron passages
(EDP Sciences, 2020)Context. PSR B1259–63/LS 2883 is a gamma-ray binary system consisting of a pulsar in an eccentric orbit around a bright Oe stellar-type companion star that features a dense circumstellar disc. The bright broad-band emission ... -
Longitudinal variation of the pickup-proton-injection efficiency and rate at the heliospheric termination shock
(EDP Sciences, 2008)Context. Pickup ions are considered to be the seed population of the anomalous cosmic rays. The acceleration of the pickup ions at the solar wind termination shock depends on the efficiency with which they are injected ... -
MSP binaries as astrophysical laboratories
(Cambridge Univ Press, 2018)Follow-up of unidentified Fermi sources has expanded the number of known galactic-field “black widow” and “redback” millisecond pulsar binaries from four to nearly 30. Several systems observed by Chandra, XMM-Newton, Suzaku, ... -
Pressure balance and intrabinary shock stability in rotation-powered-state redback and transitional millisecond pulsar binary systems
(IOP Publishing, 2018)A number of low-mass millisecond pulsar (MSP) binaries in their rotation-powered state exhibit double-peaked X-ray orbital modulation centered at inferior pulsar conjunction. This state, which has been known to persist for ... -
Probing acceleration and turbulence at relativistic shocks in blazar jets
(Oxford Univ Press, 2017)Diffusive shock acceleration (DSA) at relativistic shocks is widely thought to be an important acceleration mechanism in various astrophysical jet sources, including radio-loud active galactic nuclei such as blazars. Such ... -
Supernova remnant evolution in uniform and non-uniform media
