Long-term uGMRT Observations of Repeating FRB 20220912A

This paper presents a long-term monitoring campaign of the repeating Fast Radio Burst (FRB) 20220912A using the uGMRT. The study's significance lies in its extended observation period (nearly two years) and the detection of a large number of bursts (643) at low radio frequencies. The analysis of the energy distributions and activity patterns provides valuable insights into the emission mechanisms and potential progenitor models of this hyperactive FRB. The comparison with other active repeaters strengthens the understanding of common underlying processes.

• •FRB 20220912A shows sustained high activity over a long period.
• •The energy distributions exhibit a break, similar to other active repeaters.
• •The findings support progenitor models involving young dynamic magnetars.
