Unveiling the Local Environment of FRB 20220912A: Sub-arcsecond GHz Radio Continuum Mapping
Yash Bhusare, Yogesh Maan, Mohit Bhardwaj +4
The local environments of repeating fast radio bursts (FRBs) provide critical clues to their progenitors. While some active repeaters (e.g., FRB~20121102A, FRB~20190520B) are embed…
Long-term monitoring of repeating FRB 20220912A with the uGMRT at low radio frequencies
Ajay Kumar, Yogesh Maan, Banshi Lal +4
Some repeating FRBs exhibit occasional extreme repetition rates, but very few show a sustained high activity level. One such hyperactive repeater is FRB 20220912A, which was discov…
Low-energy Radio Bursts from Magnetar XTE J1810197: Implications for Fast Radio Bursts
Banshi Lal, Yogesh Maan, Moaz Abdelmaguid +3
Magnetars are the leading candidate sources of fast radio bursts (FRBs). However, the observational probes of the connections between magnetars and FRBs are severely limited by the…
Low-frequency Probes of the Persistent Radio Sources associated with Repeating FRBs
Yash Bhusare, Yogesh Maan, Ajay Kumar
The discovery of Persistent Radio Sources (PRSs) associated with three repeating fast radio bursts (FRBs) has provided insight into the local environments of these FRBs. Here, we p…
A direct measurement of the electron density turbulence parameter and implications for the emission size of the magnetar XTE J1810-197
Visweshwar Ram Marthi, Yogesh Maan
We report a direct measurement of the electron density turbulence parameter , enabled by 550-750~MHz baseband observations with the upgraded Giant Metrewave Radio Telescope. T…
