Decade-long Timing Study of the Black Widow Millisecond Pulsar J1544+4937
The Astrophysical Journal, 2023 Results from 11 yr of radio timing for the eclipsing black widow millisecond pulsar (MSP) binary J1544+4937 is presented in this paper. We report a phase-connected timing model for this MSP, using observations with the Giant Metrewave Radio Telescope ...

Scattering Delay Mitigation in High-accuracy Pulsar Timing: Cyclic Spectroscopy Techniques
The Astrophysical Journal, 2023 We simulate scattering delays from the interstellar medium to examine the effectiveness of three estimators in recovering these delays in pulsar timing data. Two of these estimators use the more traditional process of fitting autocorrelation functions to

An evidence based time-frequency search method for gravitational waves from pulsar glitches
Journal of Physics: Conference Series, 2008 We review and expand on a Bayesian model selection technique for the detection of gravitational waves from neutron star ring-downs associated with pulsar glitches. The algorithm works with power spectral densities constructed from overlapping time segments of gravitational wave data.

Pulsar timing methods for evaluating dispersion measure time series
Astronomy & AstrophysicsContext. Radio pulsars can be used for many studies, including the investigation of the ionized interstellar medium and the solar wind via their dispersive effects. These phenomena affect the high-precision timing of pulsars and are among the main sources of noise in experiments searching for low-frequency gravitational waves in pulsar data. Aims.

PSR J1838−0655: X-Ray Observations with NICER and NuSTAR
The Astrophysical JournalWe report on the timing and spectral properties of PSR J1838-0655 using joint observations from the Neutron Star Interior Composition Explorer (NICER) and the Nuclear Spectroscopic Telescope Array (NuSTAR). By disentangling the pulsar’s emission from its

Timing gamma-ray pulsars using Gibbs sampling
Astronomy & AstrophysicsTiming analyses of gamma-ray pulsars in the Fermi Large Area Telescope (LAT) dataset can provide sensitive probes of many astrophysical processes, including timing noise in young pulsars, orbital period variations in redback binaries, and the stochastic ...

Carbon Energy, EarlyView.The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.
