Noise Budget and Interstellar Medium Mitigation Advances in the NANOGrav Pulsar Timing Array
T. Dolch, S. Chatterjee, J. M. Cordes +9
Gravitational wave (GW) detection with pulsar timing arrays (PTAs) requires accurate noise characterization. The noise of our Galactic-scale GW detector has been systematically eva…
Wavelet Denoising of Radio Observations of Rotating Radio Transients (RRATs): Improved Timing Parameters for Eight RRATs
Min Jiang, Bingyi Cui, Natalia Schmid +2
Rotating radio transients (RRATs) are sporadically emitting pulsars detectable only through searches for single pulses. While over 100 RRATs have been detected, only a small fracti…
ALFABURST: A commensal search for Fast Radio Bursts with Arecibo
Griffin Foster, Aris Karastergiou, Golnoosh Golpayegani +12
ALFABURST has been searching for Fast Radio Bursts (FRBs) commensally with other projects using the Arecibo L-band Feed Array (ALFA) receiver at the Arecibo Observatory since July…
Commissioning of FLAG: A phased array feed for the GBT
K. M. Rajwade, N. M. Pingel, R. A. Black +14
Phased Array Feed (PAF) technology is the next major advancement in radio astronomy in terms of combining high sensitivity and large field of view. The Focal L-band Array for the G…
CHIME FRB: An application of FFT beamforming for a radio telescope
C. Ng, K. Vanderlinde, A. Paradise +11
We have developed FFT beamforming techniques for the CHIME radio telescope, to search for and localize the astrophysical signals from Fast Radio Bursts (FRBs) over a large instanta…
