Coherent Inverse Compton Scattering by Bunches in Fast Radio Bursts

Bing Zhang

Summary: The emission mechanism of fast radio bursts (FRBs) requires high coherence. This paper proposes a new model that explains the emission of FRBs through the coherent inverse Compton scattering (ICS) of bunched particles. The model can account for the observed narrowband spectrum and frequency downdrifting pattern.

Magnetospheric Curvature Radiation by Bunches as Emission Mechanism for Repeating Fast Radio Bursts

Wei-Yang Wang et al.

Summary: The study investigates coherent curvature radiation as the radiation mechanism for fast radio bursts (FRBs), finding that FRBs may be generated by charged bunches in the magnetosphere of highly magnetized neutron stars. The findings suggest that the spectra of FRBs can be characterized by multisegmented broken power laws and the polarization properties depend on the relative position between the line of sight and the beam of emitted waves.

A Sudden Period of High Activity from Repeating Fast Radio Burst 20201124A

Adam E. Lanman et al.

Summary: This paper reports on the bursts detected by CHIME/FRB from the repeating FRB 20201124A, including their morphologies, fluences, and arrival times. The observations show a significant change in the event rate before and after discovery. Through maximum-likelihood estimation, we find a best-fit index for a power-law luminosity function that is consistent with other repeating FRBs.

Temporal Scattering, Depolarization, and Persistent Radio Emission from Magnetized Inhomogeneous Environments near Repeating Fast Radio Burst Sources

Yuan-Pei Yang et al.

Summary: This study investigates the complex polarization behaviors of repeating fast radio burst (FRB) sources and their relation to temporal scattering, depolarization by RM scatter, and compact persistent radio sources (PRSs). The results suggest that the magnetized plasma environment surrounding the FRB source plays a significant role in the observed polarization behaviors. The findings also indicate a strong correlation between the RM scatter and temporal scattering. Additionally, FRBs with compact PRSs tend to exhibit extreme RM values.

Circularly polarized radio emission from the repeating fast radio burst source FRB 20201124A

P. Kumar et al.

Summary: The mechanism and emission properties of repeating fast radio burst (FRB) sources are not well understood. In this study, observations of the FRB source 20201124A were conducted using the Australian Square Kilometre Array Pathfinder (ASKAP) and the Ultra-wideband Low (UWL) receiver at the Parkes 64-m radio telescope. The results show significant findings, including the brightest burst ever observed from a repeating FRB source with ASKAP, highly polarized bursts from UWL, and evidence of circular polarization in one of the UWL bursts.

FRB 121102: Drastic changes in the burst polarization contrasts with the stability of the persistent emission

A. Plavin et al.

Summary: This study investigates the properties of the persistent radio counterpart to FRB 121102 and a bright burst. The observations reveal the highest burst Faraday rotation measure to date, consistent with a decreasing trend. The width of the burst environment and the fractional polarization can be reconciled, suggesting possible non-uniformities or effects in the emitting region itself. The size of the persistent source is barely consistent with a young supernova scenario, and the flux variability and fractional polarization of the faint persistent source challenge other interpretations.

Frequency-dependent polarization of repeating fast radio bursts implications for their origin

Yi Feng et al.

Summary: Observations of five repeating FRBs revealed a trend of lower polarization at lower frequencies. This behavior can be modeled as multipath scattering, characterized by the rotation measure (RM) scatter. Sources with higher RM scatter have higher RM magnitude and scattering time scales. Furthermore, the two sources with the highest RM scatter are associated with compact persistent radio sources.

Summary: The dispersive sweep of fast radio burstsreveals the ionized baryon content of intergalactic medium. The detection and localization of repeating FRB 20190520B with a persistent radio source co-located suggests caution in inferring redshifts for FRBs without accurate host-galaxy identifications.

Repeating fast radio bursts: Coherent circular polarization by bunches

Wei-Yang Wang et al.

Summary: This study revisits the polarized FRB emission and investigates the production mechanisms of highly circular polarization. By deriving the intrinsic mechanism and propagative effect, it is found that the coherent summation of waves generated or scattered by bunches can naturally explain highly circular polarization. This has important implications for future observations.

Summary: This study reports the continuous observations of FRB 20201124A, revealing the irregular time variation and circular polarization of its radio bursts.

Summary: The study reports the properties of more than 800 bursts from the repeating fast radio burst source FRB 20201124A, without finding credible spin periods, while questioning some theoretical scenarios.

Fast Radio Bursts and Their High-energy Counterparts from Magnetar Magnetospheres

Yuan-Pei Yang et al.

Summary: Fast radio bursts (FRBs) may originate from magnetar activities triggered by crust fracturing, with a higher fracturing rate in polar regions leading to a higher likelihood of FRBs being triggered near multipolar magnetic poles. Magnetars with stronger magnetic fields tend to produce brighter and more frequent repeated bursts.

Fast radio burst detection in the presence of coloured noise

C. F. Zhang et al.

Summary: This study investigates the impact of correlated noise on the search for fast radio bursts (FRBs), finding that it significantly increases false alarm probability, raises signal-to-noise ratios of false positives, and affects the pulse width distribution. Demonstrating the application of correlated noise modeling with observations of the M82 galaxy, the study also discusses a low signal-to-noise candidate and its possible origins. Both an M82-harbored giant pulse and a cosmological FRB are compatible with the observed data.

Summary: Fast radio burst FRB 20180916B repeats with a periodicity of 16 days and emits down to a frequency of 120 MHz, showing a frequency-dependent activity window. The results suggest that some FRBs are found in 'clean' environments without absorption of low-frequency radiation, indicating possible scenarios of low-frequency FRB emission escaping local medium.
