Probing the emission states of PSR J1107-5907
Jingbo Wang, George Hobbs, Matthew Kerr +14
The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very…
Periodic Fast Radio Bursts from Young Neutron Stars
Julian B. Muñoz, Vikram Ravi, Abraham Loeb
Fast radio bursts (FRBs) are highly energetic radio pulses from cosmological origins. Despite an abundance of detections, their nature remains elusive. At least a subset of FRBs is…
The DSA-2000 -- A Radio Survey Camera
G. Hallinan, V. Ravi, S. Weinreb +25
We present the DSA-2000: a world-leading radio survey telescope and multi-messenger discovery engine for the next decade. The array will be the first true radio camera, outputting…
The prevalence of repeating fast radio bursts
Vikram Ravi
Fast radio bursts are extragalactic, sub-millisecond radio impulses of unknown origin [1,2]. Their dispersion measures, which quantify the observed frequency-dependent dispersive d…
A fast radio burst localised to a massive galaxy
V. Ravi, M. Catha, L. D'Addario +9
Intense, millisecond-duration bursts of radio waves have been detected from beyond the Milky Way [1]. Their extragalactic origins are evidenced by their large dispersion measures,…
Finding Strong Gravitational Lenses in the DESI DECam Legacy Survey
X. Huang, M. Domingo, A. Pilon +17
We perform a semi-automated search for strong gravitational lensing systems in the 9,000 deg Dark Energy Camera Legacy Survey (DECaLS), part of the DESI Legacy Imaging Surveys…
Five new real-time detections of Fast Radio Bursts with UTMOST
W. Farah, C. Flynn, M. Bailes +25
We detail a new fast radio burst (FRB) survey with the Molonglo Radio Telescope, in which six FRBs were detected between June 2017 and December 2018. By using a real-time FRB detec…
Multi-Messenger Astrophysics with Pulsar Timing Arrays
Luke Zoltan Kelley, Maria Charisi, Sarah Burke-Spolaor +29
Pulsar timing arrays (PTAs) are on the verge of detecting low-frequency gravitational waves (GWs) from supermassive black hole binaries (SMBHBs). With continued observations of a l…
Fast Radio Burst Tomography of the Unseen Universe
Vikram Ravi, Nicholas Battaglia, Sarah Burke-Spolaor +13
The discovery of Fast Radio Bursts (FRBs) at cosmological distances has opened a powerful window on otherwise unseen matter in the Universe. In the 2020s, observations of …
Faraday conversion and magneto-ionic variations in Fast Radio Bursts
H. K. Vedantham, V. Ravi
The extreme, time-variable Faraday rotation observed in the repeating fast radio burst (FRB) 121102 and its associated persistent synchrotron source demonstrates that some FRBs ori…
