Optical Identification of the Shortest-period Spider Pulsar System M71E

The Astrophysical Journal, 2023
M71E is a spider pulsar (i.e., a millisecond pulsar with a tight binary companion) with the shortest known orbital period of P = 53.3 minutes, which was discovered by Pan et al.

Using Long-term Millisecond Pulsar Timing to Obtain Physical Characteristics of the Bulge Globular Cluster Terzan 5 [PDF]

, 2016
Over the past decade, the discovery of three unique stellar populations and a large number of confirmed pulsars within the globular cluster Terzan 5 has raised questions over its classification.

LOFAR Discovery of the Fastest-spinning Millisecond Pulsar in the Galactic Field [PDF]

, 2017
We report the discovery of PSR J0952−0607, a 707 Hz binary millisecond pulsar that is now the fastest-spinning neutron star known in the Galactic field (i.e., outside of a globular cluster).

Improved Galactic diffuse emission model strengthens the case for a Millisecond Pulsar explanation of the Fermi GeV excess

SciPost Physics Proceedings, 2023
After more than a decade since its discovery, the Galactic center gamma-ray excess - discovered with the Fermi Large Area Telescope - remains puzzling. While the spectrum of the signal can be explained by either dark matter or an unresolved population of

Discovery of an Isolated Compact Object at High Galactic Latitude

, 2007
We report discovery of a compact object at high Galactic latitude. The object was initially identified as a ROSAT All-Sky Survey Bright Source Catalog X-ray source, 1RXS J141256.0+792204, statistically likely to possess a high X-ray to optical flux ratio.

Implications of the PSR 1257+12 Planetary System for Isolated Millisecond Pulsars [PDF]

, 2000
The first extrasolar planets were discovered in 1992 around the millisecond pulsar PSR 1257+12. We show that recent developments in the study of accretion onto magnetized stars, plus the existence of the innermost, moon-sized planet in the PSR 1257+12 ...

A glitch in the millisecond pulsar J0613-0200 [PDF]

, 2016
We present evidence for a small glitch in the spin evolution of the millisecond pulsar J0613−0200, using the EPTA Data Release 1.0, combined with Jodrell Bank analogue filterbank TOAs recorded with the Lovell telescope and Effelsberg Pulsar Observing ...

Strong Support for the Millisecond Pulsar Origin of the Galactic Center GeV Excess. [PDF]

Physical Review Letters, 2015
Using γ-ray data from the Fermi Large Area Telescope, various groups have identified a clear excess emission in the Inner Galaxy, at energies around a few GeV. This excess resembles remarkably well a signal from dark-matter annihilation.

Whistler Chorus Amplification in the Magnetosphere: The Nonlinear Free‐Electron Laser Model and the Ginzburg‐Landau Equation

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present a novel nonlinear model for whistler‐mode chorus amplification based on the free‐electron laser (FEL) mechanism. First, we derive the nonlinear collective variable equations for the whistler‐electron interaction. Consistent with in situ satellite observations, these equations predict that a small seed wave can undergo exponential ...
