IXPE Observations of Magnetar Sources
GalaxiesAmong the more than 60 sources observed in the first two years of operations, IXPE addressed four magnetars, neutron stars believed to host ultra-strong magnetic fields. We report here the main implication coming from IXPE measurements for the physics of

Cosmic Analogues of the Stern-Gerlach Experiment and the Detection of Light Bosons
, 2008 We show that, by studying the arrival times of radio pulses from highly-magnetized pulsars, it may be possible to detect light spin-0 bosons (such as axions and axion-like particles) with a much greater sensitivity, over a broad particle mass range than ...

Axion production from Landau quantization in the strong magnetic field of magnetars
Physics Letters B, 2018 We utilize an exact quantum calculation to explore axion emission from electrons and protons in the presence of the strong magnetic field of magnetars. The axion is emitted via transitions between the Landau levels generated by the strong magnetic field.

Neutron Star Merger Remnants: Braking Indices, Gravitational Waves, and the Equation Of State
, 2019 The binary neutron star merger GW170817/GRB170817A confirmed that at least some neutron star mergers are the progenitors of short gamma-ray bursts. Many short gamma-ray bursts have long-term x-ray afterglows that have been interpreted in terms of post ...

The Self-organized Criticality Behaviors of Pulses in Magnetar Bursts
The Astrophysical Journal Supplement SeriesThe overall temporal and spectral characteristics (e.g., duration, fluence, peak flux, peak count rate, and total counts) of X-ray bursts (XRBs) originating from magnetars have been extensively studied to confirm their self-organized criticality (SOC ...

Frontiers in Astronomy and Space SciencesWe explain the braking index n=2.19±0.03 of PSR J1846−0258 by incorporating the time evolution of its magnetic inclination angle and dipolar magnetic field. Based on observational timing data and the age of the associated supernova remnant (tSNR≈1.77kyr),

An Energetic Magnetar in HESS J1713-381/CTB 37B
, 2010 We obtained a second Chandra timing measurement of the 3.82 s pulsar CXOU J171405.7-381031 in the supernova remnant (SNR) CTB 37B, which shows that it is spinning down rapidly.

Instability in Supernova Fallback Disks and Its Effect on the Formation of Ultralong Period Pulsars
The Astrophysical JournalSeveral pulsars with unusually long periods were discovered recently, comprising a potential population of ultralong period pulsars (ULPPs). The origin of their long periodicity is not well understood, but may be related to magnetars spun down by ...

Astrophysical Journal, 2019 The afterglow emission of some gamma-ray bursts (GRBs) shows a shallow decay (plateau) phase implying continuous injection of energy. The source of this energy is very commonly attributed to the spin-down power of a nascent millisecond magnetar.

The Astrophysical JournalFast blue optical transients (FBOTs) are luminous, rapidly evolving events with blue spectra, possibly powered by newborn magnetars and linked to fast radio bursts (FRBs).
