γ-Ray Pulsar Emission is Mostly Stable on Timescales from Minutes to Years
The Astrophysical JournalWe present a method for the detection and characterization of random changes in the flux from γ -ray pulsars on sub-hour timescales, much shorter than variations that can be accessed using direct flux measurements.

Pulsar timing in extreme mass ratio binaries: a general relativistic approach
, 2019 The detection of a pulsar (PSR) in a tight, relativistic orbit around a supermassive or intermediate mass black hole - such as those in the Galactic centre or in the centre of Globular clusters - would allow for precision tests of general relativity (GR)

Enhancing CHO cell recombinant protein production using a perfusion‐directed host evolution approach
Biotechnology Progress, Volume 42, Issue 2, March/April 2026.Abstract Clonally derived cell lines generated from Chinese hamster ovary (CHO) cells encounter numerous stressors when cultured in high‐intensity perfusion bioreactors leading to poor process performance. To circumvent this, the ability of CHO cells to adapt to different culture environments was exploited. Here host cells were selected in the presence

The Accreting Millisecond X-ray Pulsar IGR J00291+5934: Evidence for a Long Timescale Spin Evolution
, 2010 Accreting Millisecond X-ray Pulsars like IGR J00291+5934 are important because it is possible to test theories of pulsar formation and evolution. They give also the possibility to constrain gravitational wave emission theories and the equation of state ...

Autonomous Spacecraft Navigation Based on Pulsar Timing Information
, 2011 We discuss the possibility of an autonomous navigation system for spacecraft that is based on pulsar timing data. Pulsars are rapidly rotating neutron stars that are observable as variable celestial sources of electromagnetic radiation.

CHIME-o-Grav: Wideband Timing of Four Millisecond Pulsars from the NANOGrav 15 yr Dataset
The Astrophysical JournalWideband timing of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) datasets was first done for the 12.5 yr dataset. This method, where a single time of arrival and a single dispersion measure (DM) are measured using the entire

Limits on the Mass, Velocity and Orbit of PSR J1933$-$6211
, 2017 We present a high-precision timing analysis of PSR J1933$-$6211, a millisecond pulsar (MSP) with a 3.5-ms spin period and a white dwarf (WD) companion, using data from the Parkes radio telescope.

A Novel Technique for Long-term Timing of Redback Millisecond Pulsars
The Astrophysical JournalWe present timing solutions spanning nearly two decades for five redback (RB) systems found in globular clusters (GCs), created using a novel technique that effectively “isolates” the pulsar. By accurately measuring the time of passage through periastron

Discovery of 28 pulsars using new techniques for sorting pulsar candidates
, 2009 Modern pulsar surveys produce many millions of candidate pulsars, far more than can be individually inspected. Traditional methods for filtering these candidates, based upon the signal-to-noise ratio of the detection, cannot easily distinguish between ...
