Pulse variation of the optical emission of Crab pulsar
S. Karpov, G. Beskin, A. Biryukov +3
The stability of the optical pulse of the Crab pulsar is analyzed based on the 1 s resolution observations with the Russian 6-meter and William Hershel telescopes equipped with…
A new survey of variability in the core of M15 with TRIFFID-2
Seathrun O'Tuairisg, Raymond Butler, Andy Shearer +2
A two-week campaign of high-resolution imaging of the centre of M15 using the tip/tilt correcting TRIFFID-2 camera, followed by analysis with ISIS (image matching & subtraction sof…
PSR B1951+32 and PSR J0537-6910 - where are the optical counterparts?
R. F. Butler, A. Golden, A. Shearer +1
There remain several definitive gamma-ray pulsars that are as yet undetected in the optical regime. A classic case is the pulsar PSR B1951+32, associated with the complex CTB 80 SN…
A 2.14 ms Candidate Optical Pulsar in SN1987A
J. Middleditch, J. A. Kristian, W. E. Kunkel +10
We have monitored Supernova 1987A in optical/near-infrared bands from a few weeks following its birth until the present time in order to search for a pulsar remnant. We have found…
High Speed Phase-Resolved 2-d UBV Photometry of the Crab pulsar
A. Golden, A. Shearer, R. M. Redfern +5
We report a phase-resolved photometric and morphological analysis of UBV data of the Crab pulsar obtained with the 2-d TRIFFID high speed optical photometer mounted on the Russian…
PSR B0656+14: Combined Optical, X-ray & EUV Studies
Aaron Golden, Andy Shearer, Jerry Edelstein
PSR B0656+14's high energy emission is consistent with that of combined magnetospheric and thermal (surface & polar cap) emission. Uncertainties with the radio-derived distance and…
