Accelerating high-energy pulsar radiation codes
(IOP Publishing, 2010)Curvature radiation (CR) is believed to be a dominant mechanism for creating gamma-ray emission from pulsars and is emitted by relativistic particles that are constrained to move along curved magnetic field lines. Additionally, ... -
Discovery of pulsed γ-rays from PSR J0034-0534 with the Fermi Large Area Telescope: a case for co-located radio and γ-ray emission regions
(IOP Publishing, 2010)Millisecond pulsars (MSPs) have been firmly established as a class of γ-ray emitters via the detection of pulsations above 0.1 GeV from eight MSPs by the Fermi Large Area Telescope (LAT). Using 13 months of LAT data, ... -
Discovery of two millisecond pulsars in Fermi sources with the nançay radio telescope
(IOP Publishing, 2011)We report the discovery of two millisecond pulsars in a search for radio pulsations at the positions of Fermi-Large Area Telescope sources with no previously known counterparts, using the Nan¸cay Radio Telescope. The two ... -
Fermi Large Area Telescope observations of PSR J1836+5925
(IOP Publishing, 2010)The discovery of the γ-ray pulsar PSR J1836+5925, powering the formerly unidentified EGRET source 3EG J1835+5918, was one of the early accomplishments of the Fermi Large Area Telescope (LAT). Sitting 25° off the Galactic ... -
Fermi Large Area Telescope observations of the Vela-X pulsar wind nebula
(IOP Publishing, 2010)We report on gamma-ray observations in the off-pulse window of the Vela pulsar PSR B0833–45 using 11 months of survey data from the Fermi Large Area Telescope (LAT). This pulsar is located in the 8° diameter Vela supernova ... -
Fermi LAT pulsed detection of PSR J0737-3039A in the double pulsar system
(IOP Publishing, 2013)We report the Fermi Large Area Telescope discovery of γ-ray pulsations from the 22.7 ms pulsar A in the double pulsar system J0737−3039A/B. This is the first mildly recycled millisecond pulsar (MSP) detected in the GeV ... -
Fermi-LAT observations of the Geminga pulsar
(IOP Publishing, 2010)We report on the Fermi-LAT observations of the Geminga pulsar, the second brightest non-variable GeV source in the γ-ray sky and the first example of a radio-quiet γ-ray pulsar. The observations cover one year, from the ... -
The first Fermi Large Area Telescope catalog of gamma-ray pulsars
(IOP Publishing, 2010)The dramatic increase in the number of known gamma-ray pulsars since the launch of the Fermi Gamma-ray Space Telescope (formerly GLAST) offers the first opportunity to study a sizable population of these high-energy objects. ... -
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 ... -
Hard spectral tails in magnetars
(Cambridge Univ Press, 2017)Pulsed non-thermal quiescent emission between 10 keV and around 150 keV has been observed in ~10 magnetars. For inner magnetospheric models of such hard X-ray signals, resonant Compton upscattering of soft thermal photons ...
