We report the first rotation powered pulsars discovered in the Small
Magellanic Cloud (SMC) in more than a decade. PSR J0043-73 and PSR J0052-72
were discovered during a Parkes Multi-Beam (PMB) survey of MCSNR J0127-7332,
and five new, optically selected, supernova remnant (SNR) candidates identified
by the XMM Newton survey. In addition to the candidates, we adjusted the PMB
rotation to include an additional nine SNRs and pulsar wind nebulae. We
searched for young pulsars (1 – 200 ms) employing a Fourier analysis with
PRESTO, as well as a search for longer period pulsars (200 ms – 360 s) with a
fast folding algorithm. Our targeted survey had a limiting flux density of
0.039 mJy for periods greater than 50 ms. Although not the main target of this
search it was also sensitive to millisecond pulsars. PSR J0043-73 has a period
and dispersion measure of 937.42937 (26) ms and 115.1 (3.4) pc cm$^{-3}$
respectively, and PSR J0052-72 has a period of 191.444328 (46) ms and a DM of
158.6 (1.6) pc cm$^{-3}$.
