Summary: The detection of FRB 200428 coincident with an XRB from the Galactic magnetar SGR J1935+2154 suggests that magnetars can produce FRBs. By analyzing X-ray and radio observations, the geometric and relativistic beaming factors of FRBs are constrained. This study is important for understanding the formation mechanism of FRBs.

Summary: The radius-to-frequency mapping in fast radio bursts (FRBs) is further explored in this study, with an analytical treatment presented based on the work of Lyutikov (2020, ApJ, 889, 135). The frequency dependence of drifting rate and drifting time-scale is obtained, considering the aberration effect and twist of magnetic field lines. The results show that burst width in FRBs is larger at lower frequencies, and repeaters may have larger magnetic fields compared to non-repeaters, resulting in wider burst widths according to the radius-to-frequency mapping.

Summary: A universal correlation between X-ray luminosity and radio luminosity has been found, indicating a common origin for the energetic electrons producing X-ray flares and radio emissions. The similarities in energy, duration, and waiting time between solar radio bursts, Galactic magnetars, and repeating FRBs support this correlation.

Summary: Research shows a universal correlation between X-ray and radio emissions, suggesting a common origin for the energetic electrons producing these emissions. This correlation helps in understanding the generation process of radio bursts. Additionally, statistical similarities in energy, duration, and waiting time distributions among solar radio bursts, SGR 1935+2154, and repeating FRB 121102 indicate that these phenomena can be treated as scaled-up solar radio bursts.

Summary: We study the statistical properties of the soft gamma repeater SGR 1935+2154 and find similar features and scale-invariant structure as the repeating fast radio burst FRB 121102, indicating an underlying association between the origins of soft gamma repeaters and repeating fast radio bursts.

Summary: Recently, a physical connection between antiglitch/glitch and fast radio burst (FRB)-like bursts of the Galactic magnetar SGR J1935+2154 has been discovered. A proposed model suggests that these phenomena can be explained by an asteroid tidally captured and disrupted by the magnetar, leading to sudden changes in rotational frequency and the production of bright radio bursts. This model provides a unified explanation for the observed events.

Summary: Two recent discoveries, namely PSR J0901-4046 and GLEAM-X J162759.5-523504.3, have confirmed the existence of radio-loud periodic sources with long periods. These sources cannot be explained by rotation losses, and GLEAM-X J1627 is considered to be a highly magnetized object consistent with a magnetar. The presence of these objects suggests a widespread survival of magnetar-like fields and they may also be a second class of FRB progenitors.

Summary: Recent observations of the periodic fast radio burst source FRB 180916 show small linear polarization position angle swings during and between bursts, with narrower and earlier burst windows at higher frequencies. The authors propose altitude-dependent radio emission from a magnetar to explain the observations, suggesting that the periodicity in FRB 180916 may originate from the motion of a bursting magnetar. Further observational tests are proposed to differentiate between theories and identify the true explanation for the periodicity.

Summary: Magnetars have been identified as a potential energy source for fast radio bursts (FRBs), potentially formed by core-collapse explosions and compact binary mergers. The expansion of merger ejecta can produce time-evolving dispersion measure and rotation measure to probe local environments of FRBs. Research has shown that in the binary neutron star merger scenario, the age of the FRB source is estimated to be around 9-10 years, with an ambient medium density of approximately 2.5-3.1 cm(-3).

Summary: This study compares the distribution of Galactic magnetars, pulsars, and X-ray binaries with extragalactic transient samples, finding that fast radio bursts (FRBs) closely follow the distribution of Galactic neutron stars. This provides further support for FRB models involving isolated young neutron stars or binaries containing a neutron star.

Summary: Magnetars are likely responsible for some fast radio bursts (FRBs). Despite the debate over the origin of FRBs, evidence suggests that they are produced in the magnetosphere. This study investigates the suggestion that the radio waves associated with FRBs lose energy before escaping the magnetosphere. The findings show that FRB radiation in the open field line region of a magnetar's magnetosphere does not suffer significant loss due to previously ignored factors. Both plasma outflows and the alignment of magnetic field lines with FRB propagation direction reduce the interaction between FRB pulses and plasma. Therefore, the generation of FRBs in magnetar magnetospheres is confirmed.

Summary: The magnetar SGR J1935+2154 underwent a new active episode with X-ray bursts and enhanced persistent flux. A radio burst similar to fast radio bursts with an X-ray counterpart was observed, indicating that magnetars can generate fast radio bursts. X-ray spectral and timing properties of SGR J1935+2154 during a 7-month monitoring campaign were reported. The spectrum exhibited a non-thermal power-law component and a blackbody component, with the temperature of the latter decreasing over time. The luminosity decay was described by two exponential functions, and the source reached quiescence after about 80 days, releasing a significant amount of energy. The spin-down rate was estimated based on X-ray pulsations.

Summary: The energy functions of non-repeating fast radio bursts (FRBs) show Schechter function-like shapes at redshifts less than or similar to 1. The energy functions and volumetric rates of non-repeating FRBs decrease towards higher redshifts, suggesting that the event rate of non-repeating FRBs is likely controlled by old populations rather than young populations traced by the cosmic star-formation rate density.

Summary: Fast radio bursts (FRBs) are millisecond-time-scale radio transients originated from highly magnetized compact objects primarily detected in extragalactic sources and undergo scattering due to plasma density fluctuations. We report the observation of variable scattering times in the repeating FRB 20190520B, which can deviate from the typical power law. These scattering variations are likely caused by inhomogeneous plasma in the circumsource medium and can provide insights into small-scale processes within FRB environments.

Summary: This study examines the broadband polarization of 271 young radio pulsars, with a focus on circular polarization. Through defining categories for frequency- and phase-dependent polarization evolution, the researchers investigate the relationship between deviations of linear polarization position angle, circular polarization features, and frequency evolution of polarization. The study also demonstrates the evolution of polarization fraction, circular polarization contribution, and profile complexity with spin-down energy (E?).

Summary: We investigate coherent radio emission from neutron star mergers resulting from magnetospheric interaction between compact objects. Two plausible radiation mechanisms are considered, and it is shown that if one neutron star has a surface magnetic field of B-s >= 10(12)G, coherent millisecond radio bursts with characteristic temporal morphology and inclination angle dependence can be observed up to Gpc distances with next-generation radio facilities. We explore methods of identifying neutron star mergers as the origin of radio bursts using multi-messenger and multi-wavelength techniques, including fast radio burst surveys, observations of gamma-ray bursts and gravitational wave events, and follow-up observations of fast radio bursts for kilonova and radio afterglow emission. Findings for current and future observing facilities are presented, along with recommendations for verifying or constraining the model.

Summary: We report the discovery of the companion star to the millisecond pulsar PSR J1835-3259B in the Galactic globular cluster NGC 6652. Using deep photometric archival observations acquired through the Hubble Space Telescope, a bright and blue object was identified at a position compatible with that of the radio pulsar. The companion is a young white dwarf with a mass of 0.17 +/- 0.02 M (solar mass) and a surface temperature of 11,500 +/- 1900 K, indicating a highly nonconservative mass accretion phase.

Summary: This study presents the largest survey of average profiles of radio pulsars to date, using the same telescope and data reduction software. The results show a significant correlation between the radio luminosity and the spin-down energy of pulsars, contradicting previous assumptions about population synthesis studies. Furthermore, the findings suggest that magnetic dipole braking may not be the dominant factor in the evolution of pulsar rotation.

Summary: We discovered 37 pulsars from 20-year-old archival data, using a new search pipeline optimized for narrow-duty cycle pulsars. We found that folded and optimized pulsars often have higher signal-to-noise ratios compared to spectral analysis, especially for narrow duty cycle ones. Our results demonstrate the importance of reprocessing archival data and using refined search techniques to increase the discovery rate of pulsars.

Summary: In a MeerKAT observation, a radio nebula with cometary-like morphology, named 'Mini Mouse', was discovered by chance. The nebula points back towards a previously unidentified candidate supernova remnant. Precise localization using MeerKAT and FAST telescopes revealed a pulsar, PSR J1914+1054g, at the head of the nebula. The characteristics and age of the pulsar suggest a potential association with the proposed remnant.

Summary: Despite the rich phenomenology of radio pulsar polarization properties, the rotating vector model (RVM) remains the best method to determine the beam geometry of pulsars, even after 50 years since its creation. This study applied the RVM to 854 radio pulsars observed with the MeerKAT telescope, providing insights about the pulsar population as a whole. The main findings include the validity of the geometrical interpretation of position angle traverse in the majority of pulsars, the tendency of RVM failure in pulsars with high circular polarization, emission heights below 1000 km for the majority of pulsars regardless of spin period, and the presence of orthogonal mode jumps in about one third of the population. These results are weakly dependent on the pulsar spin-down energy.

Summary: We present a study on the subpulse modulation properties of 1198 pulsars using the Thousand-Pulsar-Array programme on MeerKAT. We find that about 35% of the pulsars analyzed exhibit drifting subpulses, which become more pronounced towards the death line. Furthermore, our study reveals the detailed evolution of drifting subpulses across the overall pulsar population, with the modulation period following a V-shaped evolution with respect to the characteristic age.

Summary: The newest generation of radio telescopes can survey large areas with high sensitivity and cadence, producing data volumes that require new methods to understand the transient sky. The first citizen science project dedicated to commensal radio transients, using data from the MeerKAT telescope, discovered 142 new variable sources and estimated that at least 2.1% of radio sources are varying at the sampled cadence and sensitivity. The success of volunteer engagement and scientific merit warrants the continued development of the project and the use of volunteer classifications to develop machine learning techniques for finding transients.
