Abstract (from CDS):

We have used the Effelsberg 100-m radio telescope to conduct a 1400-MHz (λ 21-cm) search for young and rapidly rotating radio pulsars along a 2 deg2 strip of the northern Galactic plane defined by 28°≤l≤30° and |b|≤0.5°. This region lies close to the Scutum spiral arm which is already known to contain a number of radio and X-ray pulsars. The search was nominally sensitive to pulsars with 1400-MHz flux densities above 0.3mJy; this represents a threefold improvement in sensitivity over all previous searches of this region of the Galaxy. Four new long-period pulsars were discovered as a result of this survey. All three previously known pulsars in this region were also detected. The four new pulsars are relatively young (<0.5Myr), weak (<1mJy) sources with dispersion measures in the range 170-910cm–3.pc. None of the newly-discovered pulsars are associated with catalogued supernova remnants.
