Flux density variability of 286 radio pulsars from a decade of monitoring
H. Kumamoto, S. Dai, S. Johnston +7
The Parkes telescope has been monitoring 286 radio pulsars approximately monthly since 2007 at an observing frequency of 1.4 GHz. The wide dispersion measure (DM) range of the puls…
A High-Resolution View of Fast Radio Burst Host Environments
Alexandra G. Mannings, Wen-fai Fong, Sunil Simha +11
We present Hubble Space Telescope (HST/WFC3) ultraviolet and infrared observations of eight fast radio burst (FRB) host galaxies with sub-arcsecond localizations, including the hos…
Searching for gravitational wave bursts from cosmic string cusps with the Parkes Pulsar Timing Array
N. Yonemaru, S. Kuroyanagi, G. Hobbs +12
Cosmic strings are potential gravitational wave (GW) sources that can be probed by pulsar timing arrays (PTAs). In this work we develop a detection algorithm for a GW burst from a…
A population analysis of pulse broadening in ASKAP Fast Radio Bursts
Hao Qiu, Ryan M. Shannon, Wael Farah +8
The pulse morphology of fast radio bursts (FRBs) provides key information in both understanding progenitor physics and the plasma medium through which the burst propagates. We pres…
Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network
K. Ackley, V. B. Adya, P. Agrawal +160
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influen…
A search for supernova-like optical counterparts to ASKAP-localised Fast Radio Bursts
Lachlan Marnoch, Stuart D. Ryder, Keith W. Bannister +10
Fast radio bursts (FRBs) are millisecond-scale radio pulses, which originate in distant galaxies and are produced by unknown sources. The mystery remains partially because of the t…
