A depolarisation census of ASKAP fast radio bursts
Pavan A. Uttarkar, Ryan M. Shannon, Kelly Gourdji +9
Fast radio bursts (FRBs) are luminous, dispersed pulses of extra-galactic origin. The physics of the emission mechanism, the progenitor environment, and their origin are unclear. S…
The Commensal Real-time ASKAP Fast Transient incoherent-sum survey
R. M. Shannon, K. W. Bannister, A. Bera +24
With wide-field phased array feed technology,the Australian Square Kilometre Array Pathfinder (ASKAP) is ideally suited to search for seemingly rare radio transient sources that ar…
Searching for the spectral depolarisation of ASKAP one-off FRB sources
Pavan A. Uttarkar, R. M. Shannon, K. Gourdji +3
Fast Radio Bursts (FRBs) are extragalactic transients of (sub-)millisecond duration that show wide-ranging spectral, temporal, and polarimetric properties. The polarimetric analysi…
Constraints on the persistent radio source associated with FRB 20190520B using the European VLBI Network
Shivani Bhandari, Benito Marcote, Navin Sridhar +7
We present very-long-baseline interferometry (VLBI) observations of a continuum radio source potentially associated with the fast radio burst source FRB 20190520B. Using the Europe…
The unseen host galaxy and high dispersion measure of a precisely-localised Fast Radio Burst suggests a high-redshift origin
Lachlan Marnoch, Stuart D. Ryder, Clancy W. James +13
FRB 20210912A is a fast radio burst (FRB), detected and localised to sub-arcsecond precision by the Australian Square Kilometre Array Pathfinder. No host galaxy has been identified…
Mapping Obscured Star Formation in the Host Galaxy of FRB 20201124A
Yuxin Dong, Tarraneh Eftekhari, Wen-fai Fong +23
We present high-resolution 1.5 6 GHz Karl G. Jansky Very Large Array (VLA) and Hubble Space Telescope (HST) optical and infrared observations of the extremely active repeating…
