Galactic Center Pulsars with the ngVLA
Geoffrey C. Bower, Shami Chatterjee, Jim Cordes +9
Pulsars in the Galactic Center (GC) are important probes of General Relativity, star formation, stellar dynamics, stellar evolution, and the interstellar medium. Despite years of s…
Fast Radio Burst 121102 Pulse Detection and Periodicity: A Machine Learning Approach
Yunfan Gerry Zhang, Vishal Gajjar, Griffin Foster +4
We report the detection of 72 new pulses from the repeating fast radio burst FRB 121102 in Breakthrough Listen C-band (4-8 GHz) observations at the Green Bank Telescope. The new pu…
Induced Polarization from Birefringent Pulse Splitting in Magnetoionic Media
Akshay Suresh, James M. Cordes
Birefringence in ionized, magnetized media is usually measured as Faraday rotation of linearly polarized radiation. However, pulses propagating through regions with very large Fara…
The implementation of a Fast-Folding pipeline for long-period pulsar searching in the PALFA survey
E. Parent, V. M. Kaspi, S. M. Ransom +31
The Pulsar Arecibo L-Band Feed Array (PALFA) survey, the most sensitive blind search for radio pulsars yet conducted, is ongoing at the Arecibo Observatory in Puerto Rico. The vast…
Highest-frequency detection of FRB 121102 at 4-8 GHz using the Breakthrough Listen Digital Backend at the Green Bank Telescope
V. Gajjar, A. P. V. Siemion, D. C. Price +28
We report the first detections of the repeating fast radio burst source FRB 121102 above 5.2 GHz. Observations were performed using the 48 GHz receiver of the Robert C. Byrd Gre…
