Abstract:
A middle-aged radio-quiet pulsar J0357+3205 was discovered in gamma
rays with Fermi and later in X-rays with Chandra and XMM-Newton
observatories. It produces an unusual thermally emitting pulsar wind
nebula that is observed in X-rays.
Deep optical observations were obtained to search for the pulsar
optical counterpart and its nebula using the Gran Telescopio Canarias
(GTC).
The direct imaging mode in the Sloan g' band was used. Archival X-ray
data were reanalysed and compared with the optical data.
Description:
The observations of the pulsar field were carried out in the Sloan
g' band with the Optical System for Imaging and low-intermediate
Resolution Integrated Spectroscopy (OSIRIS1) at the GTC in a
queue-scheduled service mode in 2012 December and 2013 January. With
the image scale of 0254/pixel (2x2 binning) and unvignetted field
size of 7.8'x7.8' available with the OSIRIS detector consisting
of a mosaic of two CCDs, we obtained four sets of 700s dithered
exposures in a grey time. The pulsar was exposed on CCD1. The
observing conditions were photometric, with seeing varying from 0.8"
to 1.0".
