Discovery of very high energy gamma-ray radiation from the bl lac 1es 0806+524
(IOP Publishing, 2008-12-19)
The high-frequency-peaked BL Lacertae object 1ES 0806+524, at redshift z = 0.138, was observed in the very high energy (VHE) gamma-ray regime by VERITAS between 2006 November and 2008 April. These data encompass the two- ...
Veritas observations of the γ‐ray binary ls i +61 303
(IOP Publishing, 2008-06-01)
LS I +61 303 is one of only a few high-mass X-ray binaries currently detected at high significance in very high energy gamma-rays. The system was observed over several orbital cycles ( between 2006 September and 2007 ...
Investigations of the magnetospheric plasma distribution in the vicinity of a pulsar. i. basic formulation
(IOP Publishing, 2008-12-01)
The magnetospheric plasma distribution in the vicinity of a pulsar at various inclination angles is investigated using a new relativistic, parallel three-dimensional particle-in-cell (PIC) code DYMPHNA3D. DYMPHNA3D uses a ...
Multiwavelength observations of markarian 421 in 2001 march: an unprecedented view on the x‐ray/tev correlated variability
(IOP Publishing, 2008-04-20)
We present a detailed analysis of week-long simultaneous observations of the blazar Mrk 421 at 2-60 keV X-rays (RXTE) and TeV gamma-rays (Whipple and HEGRA) in 2001. Accompanying optical monitoring was performed with the ...
Simultaneous absolute timing of the crab pulsar at radio and optical wavelengths
(EDP Sciences, 2008-06-24)
Context. The Crab pulsar emits across a large part of the electromagnetic spectrum. Determining the time delay between the emission at different wavelengths will allow to better constrain the site and mechanism of the ...
