A targeted search for fast radio bursts from magnetars in elliptical galaxies
S. Paine, D. R. Lorimer, S. Sirota +12
Motivated by predictions that globular clusters associated with nearby giant elliptical galaxies are prime environments for detecting fast radio bursts (FRBs) from magnetars, we re…
The RRATalog: a Galactic census of rotating radio transients
Devansh Agarwal, Evan F. Lewis, Duncan R. Lorimer +4
Rotating radio transients (RRATs) represent a significant but poorly understood component of the Galactic neutron star population, characterized by sporadic emission first detectab…
The Petabyte Project
Evan F. Lewis, Sarah Burke-Spolaor, Maura McLaughlin +6
Transient radio sources, such as fast radio bursts, intermittent pulsars, and rotating radio transients, can offer a wealth of information regarding extreme emission physics as wel…
Search for fast radio transients using Arecibo drift-scan observations at 1.4 GHz
B. B. P. Perera, A. J. Smith, S. Vaddi +12
We conducted a drift-scan observation campaign using the 305-m Arecibo telescope in January and March 2020 when the observatory was temporarily closed during the intense earthquake…
Comprehensive analysis of a dense sample of FRB 121102 bursts
Kshitij Aggarwal, Devansh Agarwal, Evan F. Lewis +5
We present an analysis of a densely repeating sample of bursts from the first repeating fast radio burst, FRB 121102. We reanalysed the data used by Gourdji et al. (2019) and detec…
Reprocessing of a Green Bank 43-meter Telescope Survey of Unidentified Bright Radio Sources for Pulsars and Radio Bursts
F. Crawford, J. Margeson, B. Nguyen +4
We have reprocessed a set of observations of 75 bright, unidentified, steep-spectrum polarized radio sources taken with the Green Bank 43-m telescope to find previously undetected…
Commissioning the HI Observing Mode of the Beamformer for the Cryogenically Cooled Focal L-band Array for the GBT (FLAG)
N. M. Pingel, D. J. Pisano, M. Ruzindana +19
We present the results of commissioning observations for a new digital beamforming back end for the Focal plane L-band Array for the Robert C. Byrd Green Bank Telescope (FLAG), a c…
Your: Your Unified Reader
Kshitij Aggarwal, Devansh Agarwal, Joseph W Kania +9
The advancement in signal processing and GPU based systems has enabled new transient detectors at various telescopes to perform much more sensitive searches than their predecessors…
A targeted search for repeating fast radio bursts associated with gamma-ray bursts
Nipuni T. Palliyaguru, Devansh Agarwal, Golnoosh Golpayegani +5
The origin of fast radio bursts (FRBs) still remains a mystery, even with the increased number of discoveries in the last three years. Growing evidence suggests that some FRBs may…
Possible periodic activity in the repeating FRB 121102
K. M. Rajwade, M. B. Mickaliger, B. W. Stappers +8
The discovery that at least some Fast Radio Bursts (FRBs) repeat has ruled out cataclysmic events as the progenitors of these particular bursts. FRB~121102 is the most well-studied…
Initial results from a realtime FRB search with the GBT
Devansh Agarwal, D. R. Lorimer, M. P. Surnis +11
We present the data analysis pipeline, commissioning observations and initial results from the GREENBURST fast radio burst (FRB) detection system on the Robert C. Byrd Green Bank T…
A Deep Targeted Search for Fast Radio Bursts from the Sites of Low-Redshift Short Gamma-Ray Bursts
D. R. Madison, D. Agarwal, K. Aggarwal +11
Some short gamma-ray bursts (SGRBs) are thought to be caused by the mergers of binary neutron stars which may sometimes produce massive neutron star remnants capable of producing e…
A fast radio burst in the direction of the Virgo cluster
Devansh Agarwal, Duncan R. Lorimer, Anastasia Fialkov +19
The rate of fast radio bursts (FRBs) in the direction of nearby galaxy clusters is expected to be higher than the mean cosmological rate if intrinsically faint FRBs are numerous. I…
Non-detection of fast radio bursts from six gamma-ray burst remnants with possible magnetar engines
Yunpeng Men, Kshitij Aggarwal, Ye Li +9
The analogy of the host galaxy of the repeating fast radio burst (FRB) source FRB 121102 and those of long gamma-ray bursts (GRBs) and super-luminous supernovae (SLSNe) has led to…
