Absorption Features in the X-ray Spectrum of an Ordinary Radio Pulsar
, 2012 The vast majority of known non-accreting neutron stars (NSs) are rotation-powered radio and/or gamma-ray pulsars. So far, their multiwavelength spectra have all been described satisfactorily by thermal and non-thermal continuum models, with no spectral ...

NICER X-Ray Observations of Seven Nearby Rotation-powered Millisecond Pulsars [PDF]
The Astrophysical Journal Letters, 2019 Abstract The Neutron star Interior Composition Explorer observed several rotation-powered millisecond pulsars (MSPs) to search for or confirm the presence of X-ray pulsations. When broad and sine-like, these pulsations may indicate thermal emission from hot polar caps at the magnetic poles on the neutron star surface. We report confident

Neutron Star Kicks and Implications for Their Rotation at Birth
The Astrophysical Journal, 2023 Neutron stars are born out of core-collapse supernovae, and they are imparted natal kicks at birth as a consequence of asymmetric ejection of matter and possibly neutrinos.

Emission From Rotation-Powered Pulsars and Magnetars [PDF]
AIP Conference Proceedings, 2005 I will review the latest developments in understanding the high-energy emission of rotation-powered pulsars and magnetically-powered Anomalous X-ray Pulsars (AXPs) and Soft Gamma-Ray Repeaters (SGRs). These fields have been extremely active in the last few years, both observationally and theoretically, driven partly by new X-ray data from Chandra, XMM ...

The glitch activity of neutron stars
, 2017 We present a statistical study of the glitch population and the behaviour of the glitch activity across the known population of neutron stars. An unbiased glitch database was put together based on systematic searches of radio timing data of 898 rotation ...

Spider Invasion Across the Galaxy [PDF]
Journal of Astronomy and Space Sciences, 2014 The nature of the exotic stellar corpses which reincarnate by consuming their companion is reviewed. Apart from sucking life from their partners, they are actually eating the doomed companions away by their deadly and powerful particle/radiation beams.

Studying the Radio Eclipse of Spider Pulsar J1816+4510 with the FAST
The Astrophysical JournalWe report on the radio eclipse properties of spider pulsar J1816+4510 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The high-sensitivity FAST observations will allow us to probe much deeper into the eclipse region of this pulsar

Swinging between rotation and accretion power in a binary millisecond pulsar
EPJ Web of Conferences, 2014 We present the discovery of IGR J18245–2452, the first millisecond pulsar observed to swing between a rotation-powered, radio pulsar state, and an accretion-powered X-ray pulsar state [31]. This transitional source represents the most convincing proof of

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.Abstract INTRODUCTION This study evaluated the efficacy of deep cervical lymphatic–venous anastomosis (dcLVA) for severe Alzheimer's disease (AD). METHODS A total of 139 severe AD patients undergoing dcLVA were enrolled, and changes in cognitive function and biomarkers were evaluated by comparing preoperative measures with postoperative outcomes over a
