Intrinsic Emission of PSR B1937+21 at 327 MHz

The Astrophysical Journal
At 327 MHz, the observed emission of PSR B1937+21 is greatly affected by scattering in the interstellar medium, on a timescale of order the pulse period.

XMM-Newton Observation and Optical Monitoring of the Candidate Redback Millisecond Pulsar 1FGL J0523.5-2529

The Astrophysical Journal
1FGL J0523.5−2529 is a Fermi selected redback millisecond pulsar candidate that exhibited luminous optical and X-ray flares in 2020–2021. We obtained a simultaneous X-ray and U -band observation with XMM-Newton in 2025, the first to cover the 16.5 hr ...

Anticorrelation Between Flux and Photon Index of Hard-X-Ray Emission from the Crab

The Astrophysical Journal
Using Swift Burst Alert Telescope event-mode data during gamma-ray burst occurrences, we conduct spectral analysis for the Crab system. From 38 good observations, which span a period of 18 yr from 2006 to 2023, we find that the Crab’s X-ray flux not only

Searching for debris disks around isolated pulsars

, 2014
Different pieces of observational evidence suggest the existence of disks around isolated neutron stars. Such disks could be formed from supernova fallback when neutron stars are born in core-collapse supernova explosions.

Rotochemical heating in millisecond pulsars

, 2005
Rotochemical heating originates in a departure from beta equilibrium due to spin-down compression in a rotating neutron star. The main consequence is that the star eventually arrives at a quasi-equilibrium state in which the thermal photon luminosity ...

SEARCH FOR GAMMA-RAY EMISSION FROM FOUR ACCRETING MILLISECOND PULSARS WITH FERMI/LAT

, 2013
We report our search for gamma-ray emission in the energy range from 100 MeV to 300 GeV from four accreting millisecond pulsars (AMPs), SAX J1808.4-3658, IGR J00291+5934, XTE J1814-338, and XTE J0929-314.
