Abstract:
PSR J1048-5832 is a young radio-pulsar that has recently been detected
in γ-rays with Fermi, and also in X-rays with Chandra and
XMM-Newton. It powers a compact pulsar wind nebula visible in X-rays
and is in many ways similar to the Vela pulsar.
We present deep optical observations made with the ESO Very Large
Telescope to search for optical counterparts of the pulsar and its
nebula and to explore their multi-wavelength emission properties.
The data were obtained in the V and R bands and were compared with
archival data in other spectral domains.
Description:
The pulsar field was imaged in the VHIGH and RSPECIAL bands with
the FOcal Reducer and low dispersion Spectrograph (FORS2) at the
VLT/UT1 (ANTU) during several service mode runs in 2010 and 2011. The
observations were performed with the standard resolution collimator
providing a pixel size of 0.25" (2x2 binning) and a field size of
6.8'x6.8'. Sets of twelve- and ten-minute dithered exposures were
obtained in the V and R bans.
