Faraday rotation of Northern hemisphere pulsars
Listed in IVOA Registry (Virtual Observatory)
Using commissioning data from the first year of operation of the Canadian Hydrogen Intensity Mapping Experiment's (CHIME) Pulsar backend system, we conduct a systematic analysis of the Faraday Rotation Measure (RM) of the Northern hemisphere pulsars detected by CHIME.
Description
We present 55 new RMs as well as obtain improved RM uncertainties for 25 further pulsars. CHIME's low observing frequency and wide bandwidth between 400 and 800MHz contribute to the precision of our measurements, whereas the high cadence observation provides extremely high signal-to-noise co-added data.
Our results represent a significant increase of the pulsar RM census, particularly regarding the Northern hemisphere. These new RMs are for sources that are located in the Galactic plane out to 10kpc, as well as off the plane to a scale height of ~16kpc. This improved knowledge of the Faraday sky will contribute to future Galactic large-scale magnetic structure and ionosphere modelling.
