TL;DR
The 8gr8 Cygnus survey using WSRT introduced a novel interferometric method to discover and time pulsars, resulting in the detection of three new pulsars and providing insights into pulsar populations in the Cygnus region.
Contribution
This paper presents a new interferometric observing mode, 8gr8, and demonstrates its effectiveness in pulsar discovery and timing in the Cygnus region.
Findings
Discovered three new pulsars with periods of 1.657, 1.099, and 0.445 seconds.
Successfully implemented the 8gr8 interferometric method for pulsar surveys.
Provided timing solutions for the newly discovered pulsars.
Abstract
Since 2004 we have been carrying out a pulsar survey of the Cygnus region with the Westerbork Synthesis Radio Telescope (WSRT) at a frequency of 328 MHz. The survey pioneered a novel interferometric observing mode, termed 8gr8 (eight-grate), whereby multiple simultaneous digital beams provide high sensitivity over a large field of view. Since the Cygnus region is known to contain OB associations, it is likely that pulsars are formed here. Simulations have shown that this survey could detect 70 pulsars, which would increase our understanding of the radio pulsar population in this region. We also aim to expand the known population of intermittent and rotating radio transient (RRAT)-like pulsars. In this paper we describe our methods of observation, processing and data analysis, and we present the first results. Our observing method exploits the way a regularly spaced, linear array of…
