A cross-match of GLEAM-X radio images with pulsar and gamma-ray catalogues yields 193 pulsar detections, 106 first-time sub-400 MHz measurements, and 106 new pulsar candidates.

abstract
We present the second data release for the GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey. This data release is an area of 12,892-deg^2 around the South Galactic Pole region covering 20h 40m <= RA <= 6h 40m, -90deg <= Dec <= +30deg. Observations were taken in 2020 using the Phase-II configuration of the Murchison Widefield Array (MWA) and covering a frequency range of 72-231MHz with twenty frequency bands. We produce a wideband source-finding mosaic over 170-231MHz with a median root mean squared noise of 1.5 (+1.5/-0.5) mJy beam^(-1). We present a catalogue of 624,866 components, including 562,302 components which are spectrally fit. This catalogue is 98% complete at 50mJy, and a reliability of 98.7% at a 5sigma level, consistent with expectations for this survey. The catalogue is made available via Vizier and the PASA datastore and accompanying mosaics for this data release are made available via AAO Data Central and SkyView.

Low radio frequency detections of known pulsars and identification of new candidates with GLEAM-X: GP
A cross-match of GLEAM-X radio images with pulsar and gamma-ray catalogues yields 193 pulsar detections, 106 first-time sub-400 MHz measurements, and 106 new pulsar candidates.
