Gamma-ray emission from millisecond pulsars - an Outergap perspective [PDF]

Journal of Astronomy and Space Sciences, 2013
In this review paper we explain the following gamma-ray emission features from the millisecond pulsars. (1) Why is the dipolar field of millisecond pulsars so weak but the magnetic pair creation process may still be able to control the size of the ...

Internal Heating of Old Neutron Stars: Contrasting Different Mechanisms

, 2010
The thermal emission detected from the millisecond pulsar J0437-4715 is not explained by standard cooling models of neutron stars without a heating mechanism.

The Interplay Between IL‐6, Hepcidin, and BMPR2 Signalling in Pulmonary Arterial Hypertension: Mechanistic Insights Into Vascular Remodelling

Pulmonary Circulation, Volume 16, Issue 2, June 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) is characterized by excessive pulmonary vasoconstriction and vascular remodelling, with mutations in bone morphogenetic protein receptor type 2 (BMPR2) being the most common genetic alteration associated with the disease.

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection

Space Weather, Volume 24, Issue 4, April 2026.
Abstract TianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma can introduce pointing error noise.

Arcuate nucleus‐specific progesterone receptor knockdown in female mice is sufficient to induce PCOS‐like hyperactivity in the reproductive axis

Journal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Abstract Mammalian reproductive function is dependent upon gonadal steroid hormone feedback within the hypothalamic–pituitary–gonadal (HPG) axis. In polycystic ovary syndrome (PCOS), impaired progesterone (P4) negative feedback leads to hyperactive pulsatile secretion of luteinising hormone (LH) and impaired reproductive function.

MeV Pulsars: Modeling Spectra and Polarization

, 2017
A sub-population of energetic rotation-powered pulsars show high fluxes of pulsed non-thermal hard X-ray emission. While this MeV pulsar population includes some radio-loud pulsars like the Crab, a significant number have no detected radio or GeV ...

Environmental stress reveals new insights regarding proteome rebalancing in Arabidopsis thaliana seeds

The Plant Journal, Volume 126, Issue 2, April 2026.
SUMMARY Seeds are resilient to genetic and envirxonmental perturbation. For example, they can compensate for the loss of highly abundant seed storage proteins (SSPs) while maintaining amino acid levels and composition, a process known as proteome rebalancing.

Characterizing Timing Noise in Normal Pulsars with the Nanshan Radio Telescope

Universe
We present a decade of observations of pulse arrival times for 85 pulsars using the Nanshan radio telescope from July 2002 to March 2014. The Cholesky method can accurately estimate the covariance function of the timing residuals, significantly improving

Finding Local Parallel Electric Fields in Magnetotail Reconnection Using a Two‐Spacecraft Method

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the use of a novel two‐spacecraft Liouville‐mapping method using data from the Magnetospheric Multiscale mission to determine local magnetic‐field‐aligned (parallel) electric fields in the Earth's magnetotail. The method detects the presence of local acceleration potentials by mapping phase‐space density between electron ...
