Fast Radio Burst Discovered in the Arecibo Pulsar ALFA Survey
Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arising…
PALFA Discovery of a Highly Relativistic Double Neutron Star Binary
We report the discovery and initial follow-up of a double neutron star (DNS) system, PSR J1946$+$2052, with the Arecibo L-Band Feed Array pulsar (PALFA) survey. PSR J1946$+$2052 is a 17-ms pulsar in…
Einstein@Home discovery of a Double-Neutron Star Binary in the PALFA Survey
We report here the Einstein@Home discovery of PSR J1913+1102, a 27.3 ms pulsar found in data from the ongoing Arecibo PALFA pulsar survey. The pulsar is in a 4.95 hr double neutron star (DNS) system…
PEACE: Pulsar Evaluation Algorithm for Candidate Extraction - A Software Package for Post-analysis Processing of Pulsar Survey Candidates
An algorithm called Pulsar Evaluation Algorithm for Candidate Extraction (PEACE) which improves the efficiency of identifying pulsar signals and unlike popular machine-learning-based algorithms, no prior training data sets are required.
X-RAY OBSERVATIONS OF DISRUPTED RECYCLED PULSARS: NO REFUGE FOR ORPHANED CENTRAL COMPACT OBJECTS
We present a Chandra X-ray survey of the disrupted recycled pulsars (DRPs), isolated radio pulsars with P > 20 ms and Bs 10 4 10 5 yr, roughly 10 times the ages of the � 10 known CCOs in a similar…

The gathering of the woodpigeons at game bird feeders set up for red-legged partridges may have contributed to the outbreak of trichomoniasis, and treatment of free-living birds should be avoided in favour of other measures, as it poses risks.
Searching for pulsars using image pattern recognition
A novel artificial intelligence (AI) program that identifies pulsars from recent surveys by using image pattern recognition with deep neural nets—the PICS (Pulsar Image-based Classification System) AI.
Blandford's argument: The strongest continuous gravitational wave signal
For a uniform population of neutron stars whose spin-down is dominated by the emission of gravitational radiation, an old argument of Blandford states that the expected gravitational-wave amplitude…
Two long-term intermittent pulsars discovered in the PALFA Survey
We report the discovery of two long-term intermittent radio pulsars in the ongoing Arecibo PALFA pulsar survey. Following discovery with the Arecibo Telescope, extended observations of these pulsars…
Arecibo Pulsar Survey Using ALFA. IV. Mock Spectrometer Data Analysis, Survey Sensitivity, and the Discovery of 40 Pulsars
The on-going Arecibo Pulsar-ALFA (PALFA) survey began in 2004 and is searching for radio pulsars in the Galactic plane at 1.4 GHz. Here we present a comprehensive description of one of its main data…
