Chromatic activity window of periodic fast radio bursts: FRB 20121102A and FRB 20180916B
M. C. Espinoza-Dupouy, M. Cruces, T. Cassanelli +3
Two fast radio bursts, FRB 20121102A and FRB 20180916B, show periodic activity with cycles of 159.3 and 16.33 days, respectively. These cycles consist of active and inactive window…
Multi-Faceted Emission Properties of PSR J2129+4119 Observed with FAST
Habtamu Menberu Tedila, Di Li, Pei Wang +10
We present a detailed single-pulse study of the long-period pulsar PSR J2129+4119 using high-sensitivity FAST observations. Despite locating well below the traditional death line,…
Observing radio transients with Phased ALMA: Pulses from the Galactic Centre magnetar
J. Vera-Casanova, M. Cruces, K. Liu +7
Radio transients, such as pulsars and Fast Radio Bursts (FRBs), are primarily detected at centimetre radio wavelengths, where higher luminosities are found. However, observations o…
Constraints on the X-ray-to-radio fluence ratio of FRB 20240114A
F. Eppel, M. Krumpe, P. Limaye +8
We report on multiwavelength observations of FRB 20240114A, a nearby (z=0.13), hyperactive, repeating fast radio burst that was discovered in January 2024. We performed simultaneou…
FRB 20121102A monitoring: Updated periodicity in the L band
C. A. Braga, M. Cruces, T. Cassanelli +5
FRB 20121102A was the first fast radio burst to be observed to repeat. Since then, thousands of bursts have been detected by multiple radio telescopes around the world. Previous wo…
