Summary: The evolution of magnetic fields in neutron-star crusts is driven by the Hall effect and Ohmic dissipation until the crust reaches a point of failure where standard evolution equations are no longer valid. Plastic flow in the crust affects Hall effect, sometimes even enhancing its impact. Differences in the impact of plastic flow are more pronounced in the toroidal field compared to the poloidal field.

Summary: The study investigates the spin evolution of magnetars and potential evolutionary links to other species of neutron stars. By synthesizing magnetar populations and comparing them to observations, it is found that the B-field decay must be exponential or superexponential, and the initial spin period should be less than 2 seconds. Additionally, magnetars may be linked to XDINSs evolutionarily, but are unlikely to evolve into RRATs.

Summary: Swift J1818.0-1607, discovered in early 2020, is the fifth magnetar known with periodic radio pulsations and the fastest rotating one. Observations revealed decreasing short-term fluctuations and a long-term declining trend in its spin-frequency nu, with a derived characteristic age of about 522 years. The flux density of this magnetar increased at both 2.25 and 8.60 GHz, and its radio spectrum became flatter during the observations.

Summary: This study investigates the spin-velocity alignment and high velocity of a pulsar, suggesting that they can be explained by the electromagnetic rocket mechanism. The study finds that the kick process of the pulsar can generate a relativistic jet, which may result in a gamma-ray burst. Furthermore, the study calculates the dynamical evolution of the jet and the velocity of the burst remnant, finding consistency with observational data.

Summary: Radio-loud magnetars, like Swift J1818.0-1607, exhibit significant temporal profile evolution, spectrum inversion, and polarization mode variations, possibly due to ongoing reconfiguration of plasma and electric currents within the magnetosphere. Geometric fits suggest that the magnetar is viewed at an angle of 99 degrees from its spin axis, with a misalignment of approximately 112 degrees between its magnetic and rotation axes. This might indicate that the radio emission from this magnetar originates from magnetic field lines associated with two co-located magnetic poles.

Summary: Starquakes are likely to occur in rapidly spinning or ultra high field neutron stars. This article suggests that during a starquake, highly compressed gas containing electron-positron pairs may evaporate and erupt from inside the neutron star, causing various transient and bursting phenomena.

Summary: Swift J1818.0-1607, a radio-emitting magnetar, was discovered in X-ray outburst in March 2020. A nearly 5-month multifrequency observing campaign was conducted using telescopes in the NASA Deep Space Network, with observations at 2.2, 8.4, and 32 GHz. The flux density of Swift J1818.0-1607 increased significantly during the campaign, while the spectrum changed from uncharacteristically steep to the typical flat spectrum of radio-emitting magnetars. In addition, mode switching and a near anti-alignment between the radio and X-ray pulse profiles were observed.

Summary: This study investigates the anomalous radio and X-ray bursts from a Galactic magnetar and suggests that they may be triggered by magnetic energy injection inside the magnetosphere, producing magnetically-trapped fireballs and relativistic outflows. The properties of the outflows are constrained by combining the conditions for photon escape and the timing offset between the radio and X-ray burst spikes. The results imply the presence of extremely clean or highly-magnetized outflows.

Summary: Neutron stars that emit X-ray and γ-ray pulsed emissions must produce electron-positron pairs in the magnetosphere. However, some of these sources appear to be radio quiet, which raises the question of why. In this study, we conducted a deep radio search using the LOFAR radio telescope at 150 MHz for four neutron stars that are X-ray or γ-ray pulsars but have not shown any radio pulsations so far. While we did not detect pulsed emissions from these sources, we were able to establish strict upper limits on the radio flux density at 150 MHz, which provides valuable constraints for future studies.

Summary: The dipole magnetic field axis of neutron stars may not always cross the star's center, as observed in the millisecond pulsar J0030+0451. In such cases, the electromagnetic rocket effect can be activated, resulting in an acceleration of the star due to the net force exerted by the displaced magnetic field. This effect is relevant to explain high spatial velocities of pulsars. In this study, we analyze the impact of the rocket effect on young pulsars associated with supernova remnants and compare observational data with theoretical results.

Summary: Magnetars are a unique class of neutron stars with incredibly strong magnetic fields. Unlike normal pulsars, magnetars exhibit distinct X-ray emissions driven by their strong magnetic fields. This paper presents the results of X-ray spectra analysis of magnetars in their quiescent state. The analysis found a common fundamental plane in the space composed of non-thermal X-ray luminosity, surface temperature, and the radius of the thermally emitting region, which challenges and hints at theoretical models for understanding the magnetospheric emissions from these two classes of neutron stars.

Summary: We present the observational results of 12 MSPs discovered with FAST in the CRAFTS survey, including timing ephemeris, polarization pulse profiles, Faraday rotation measurements, and RVM fitting. These timing campaigns were conducted over 3 years with FAST and Arecibo. Majority of the MSPs are in neutron star-white dwarf binaries, with orbital periods consistent with theoretical expectations for MSP-He WD systems. One pulsar shows anomalous characteristics, with smaller spin frequency and companion mass, potentially due to low orbital inclination.

Summary: Precision timing of millisecond pulsars (MSPs) in binary systems allows for the detection of Shapiro delay, providing constraints on component masses and system orientation. This study presents timing results on seven binary MSPs using the MeerKAT radio telescope, confirming Shapiro delay in all systems and determining accurate mass measurements for three pulsars. The observations also reveal correlations between pulsar companion masses and spin period, as well as the anticorrelation between recycled pulsar mass and their companion masses.

Summary: This paper presents the results of a survey using the MeerKAT radio telescope to search for pulsars in Omega Centauri. 13 new pulsars were discovered, bringing the total number of known pulsars in this cluster to 18. At least half of them are in binary systems, and preliminary orbital constraints suggest that most of the binaries have light companions. The paper also discusses the ratio between isolated and binary pulsars, and their formation in this cluster.

Summary: We conducted rapid timing analysis of optical and X-ray observations of the X-ray transient SwiftJ1858.6-0814 in 2018 and 2019. The optical light curves exhibited slow and large amplitude 'blue' flares and fast and small amplitude 'red' flares, which are consistent with X-ray reprocessing and optically thin synchrotron emission, respectively. Correlations between the optical and X-ray light curves were observed to be time- and energy-dependent. The timing properties are in qualitative agreement with the hybrid inner hot accretion flow model.

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: We studied the polarization profiles of 22 pulsars in the globular cluster 47 Tucanae using MeerKAT radio telescope and reported precise measurements of dispersion measure (DM) and rotation measure (RM). The structure function of DM shows evidence of turbulence in the gas in the cluster, while the structure function of RM does not. Future pulsar discoveries in the cluster could help confirm the presence and localize the turbulence.

Summary: Researchers have successfully measured the kinematic and relativistic effects of PSR J1933-6211 using the MeerKAT telescope and historical Parkes data. This allowed them to determine the 3D orbital geometry and component masses of the pulsar, as well as its relationship with the white dwarf companion. They also discovered that the pulsar's mass has not significantly increased, highlighting the low accretion efficiency of the spin-up process and suggesting that observed neutron star masses are mostly influenced by supernova physics.

Summary: We report the radio and high-energy properties of a new outburst from the radio-loud magnetar 1E 1547.0-5408. The outburst was associated with a spin-up glitch and a concurrent disappearance and reappearance of persistent radio emission. The soft X-ray flux increased significantly while the hard nonthermal tail remained unchanged.

Summary: In this study, we report on the long-term recurrent patterns in the short-term variability of the soft X-ray emission of LS 5039, one of the brightest gamma-ray binary systems. We found remarkable consistency in the light curves of LS 5039 observed by NICER and Suzaku, indicating a stable long-term evolution. The short-term variability is proposed to be caused by clumps of the companion star wind impacting the X-ray production site.

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: Recent joint observations with IXPE and XMMNewton of the soft.-repeater SGR 1806-20 revealed strong polarization in its X-ray emission, with the source found at an all-time low persistent flux level. The detection of probable polarization at 4-5 keV energy range suggests a resonance Compton scattering mechanism in the magnetosphere, similar to that proposed for another bright magnetar 4U 0142+61.

Summary: The 2021 outburst of the symbiotic recurrent nova RS Oph was monitored using the Neutron Star Interior Composition Explorer Mission (NICER). The study provides a detailed view of the outburst development, revealing that the X-ray flux preceding the supersoft X-ray phase peaked almost 5 days after the optical maximum and originated from shocked ejecta. The study also finds that a quasi-periodic oscillation with varying amplitudes was consistently observed during the supersoft X-ray source (SSS) phase.
