PSR J2021+4026 in the gamma cygni region: the first variable γ-ray pulsar seen by the Fermi LAT
(IOP Publishing, 2013)
Long-term monitoring of PSR J2021+4026 in the heart of the Cygnus region with the Fermi Large Area Telescope unveiled a sudden decrease in flux above 100 MeV over a timescale shorter than a week. The "jump" was near MJD ...
Broadband pulsations from PSR B1821-24: implications for emission models and the pulsar population of M28
(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 ...
First detection of VHE y-rays from SN 1006 by HESS
(EDP Sciences, 2010)
Aims. Recent theoretical predictions of the lowest very high energy (VHE) luminosity of SN 1006 are only a factor 5 below the previously published HESS upper limit, thus motivating further in-depth observations of this ...
Discovery of VHE emission towards the Carina arm region with the H.E.S.S. telescope array: HESS J1018-589
(EDP Sciences, 2012)
The Carina arm region, containing the supernova remnant SNR G284.3–1.8, the high-energy (HE; E > 100 MeV) binary 1FGL J1018.6–5856 and the energetic pulsar PSR J1016–5857 and its nebula, has been observed with the H.E.S.S. ...
Detection of variable VHE γ-ray emission from the extra-galactic γ-ray binary LMC P3
(EDP Sciences, 2018)
Context. Recently, the high-energy (HE, 0.1–100 GeV) γ-ray emission from the object LMC P3 in the Large Magellanic Cloud (LMC) has been discovered to be modulated with a 10.3-day period, making it the first extra-galactic ...
High-energy pulsar models: developments and new questions
(Wiley, 2014)
The past few years have seen a major advance in observational knowledge of high-energy (HE) pulsars. The Fermi Large
Area Telescope (LAT) and AGILE have increased the number of known γ-ray pulsars by an order of magnitude, ...
Modeling phase-aligned gamma-ray and radio millisecond pulsar light curves
(IOP Publishing, 2012)
Since the discovery of the first eight gamma-ray millisecond pulsars (MSPs) by the Fermi Large Area Telescope, this population has been steadily expanding. Four of the more recent detections, PSR J0034–0534, PSR J1939+2134 ...
Revisiting the Westerlund 2 field with the HESS telescope array
(EDP Sciences, 2011)
Aims. Previous observations with the HESS telescope array revealed the existence of extended very-high-energy (VHE; E > 100 GeV) γ-ray emission, HESS J1023–575, coincident with the young stellar cluster Westerlund 2. At ...
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 ...
H.E.S.S. and Suzaku observations of the Vela X pulsar wind nebula
(EDP Sciences, 2019)
Context. Pulsar wind nebulae (PWNe) represent the most prominent population of Galactic very-high-energy gamma-ray sources and are thought to be an efficient source of leptonic cosmic rays. Vela X is a nearby middle-aged ...
