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…
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…
Radius & Distance Estimates of the Isolated Neutron Stars Geminga & PSR B0656+14 using Optical Photometry
A. Golden, A. Shearer
Integrated ground-based and HST optical studies of isolated neutron stars have provided important independent datasets in the determination of emission activity, particularly in th…
A Search for the Optical Counterpart of PSR B1951+32 in the Supernova Remnant CTB 80
Creidhe O'Sullivan, A. Shearer, M. Colhoun +8
Using time-resolved two-dimensional aperture photometry we have put upper limits on the pulsed emission from two proposed optical counterparts for PSR B1951+32. Our pulsed upper li…
Pulsed optical emission from Geminga
A. Shearer, A. Golden, S. Harfst +9
We present optical data which shows that G", the optical counterpart of the gamma-ray pulsar Geminga, pulses in B with a period of 0.237 seconds. The similarity between the optical…
