The Green Bank North Celestial Cap Survey. IX. Timing Follow-up for 128 Pulsars
The Astrophysical JournalThe Green Bank North Celestial Cap survey is one of the largest and most sensitive searches for pulsars and transient radio objects. Observations for the survey have finished; priorities have shifted toward long-term monitoring of its discoveries.

Measuring the Lense–Thirring Orbital Precession and the Neutron Star Moment of Inertia with Pulsars
UniverseNeutron stars (NSs) are compact objects that host the densest forms of matter in the observable universe, providing unique opportunities to study the behaviour of matter at extreme densities.

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 ...

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 ...

Tidal Interactions in Pulsar Binaries [PDF]
International Astronomical Union Colloquium, 1996 Abstract The value of using pulse timing to measure orbital variations in eccentric pulsar binaries which are close enough at periastron to interact tidally is discussed. We briefly review a model for dynamical tidal evolution which shows that chaotic orbital evolution is possible, and list several applications to real systems.

Recent Developments in Degenerate Higher Order Scalar Tensor Theories
Annalen der Physik, Volume 537, Issue 2, February 2025.Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers

Radiation Dosimetry of Binary Pulsars [PDF]
The Astrophysical Journal, 1996 Companion stars exposed to high energy radiation from a primary neutron star or accreting black hole can experience significant spallation of their heavy elements, so that their atmospheres would be extremely rich in lithium, beryllium, and especially boron. In this paper we note that the detection or non-detection of these elements, and their relative

An Algebraic Approach to Light–Matter Interactions
Advanced Physics Research, Volume 4, Issue 1, January 2025.This is a review of an algebraic approach to light–matter interactions that is theoretically powerful and computationally friendly. Theoretical expressions can be developed and manipulated conveniently thanks to the generality of the basis on which the approach rests, and a compact notation.

Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations
The Astrophysical JournalEclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.
