Zhou et al. present the first flux density measurements, spectral
indices, pulse profiles, and correlations of the spectral index with
pulsar parameters for 19 pulsars employing the Ultra-Wideband Low
(UWL) receiver on the Parkes radiotelescope, Murriyang.
PSR J1848−1952 was first discovered in a pulsar survey undertaken with
the Molonglo and Parkes radio telescopes at 408 MHz in the 1970s. The
mean pulse profile of PSR J1848−1952 at both 2368 MHz and 1369 MHz
consists of two close sharp components. The total intensity is shown
in black, linearly-polarization, and circular-polarization are shown.
The PA variations are different, but the linear and circular
polarizations are almost the same at two frequencies. The overall
pulse has obvious linear polarization, and the trailing component is
less linearly polarized than the leading component.
The sharp components suggest the pulsar is relatively nearby, as the
pulse has not been significantly scatter-broadened during its passage through
the interstellar medium, and
the ATNF Pulsar Catalog confirms the Dispersion Measure for
this pulsar (a proxy for distance) is in the lowest 5% of pulsars
for which a DM has been measured.
