Survey of COmpact sources for Pulsars and Exotic objects (SCOPE)
A targeted all-sky pulsar survey, Survey of COmpact sources
for Pulsars and Exotic objects (SCOPE), is currently being
conducted using the upgraded GMRT and GBT. In the first stage
of the survey, all the compact sources which are visible at
147.5 MHz in the TIFR GMRT Sky Survey (TGSS) but not at the
higher radio frequencies, such as in the rapid ASKAP continuum
survey (RACS) or in the NRAO VLA Sky Survey (NVSS), and have
spectral indices steeper than -1.8, are being targeted. In the
GMRT SCOPE (GM-SCOPE) survey, each target is observed twice, at
two different epochs, and at band-3 (300-500 MHz) as well as
band-4 (550-750 MHz).
