Search for an Isotropic Gravitational-wave Background with the Parkes Pulsar Timing Array [PDF]
Astrophysical Journal Letters, 2023 Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common to all pulsars, with a signature spatial correlation.

A Massive Pulsar in a Compact Relativistic Binary [PDF]
Science, 2013 Introduction Neutron stars with masses above 1.8 solar masses (M☉), possess extreme gravitational fields, which may give rise to phenomena outside general relativity.

Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar
Nature Astronomy, 2019Despite its importance to our understanding of physics at supranuclear densities, the equation of state (EoS) of matter deep within neutron stars remains poorly understood. Millisecond pulsars (MSPs) are among the most useful astrophysical objects in the

Pulsar Magnetospheres and Their Radiation
Annual Review of Astronomy and Astrophysics, 2022The discovery of pulsars opened a new research field that allows studying a wide range of physics under extreme conditions. More than 3,000 pulsars are currently known, including especially more than 200 of them studied at gamma-ray frequencies.

Pulsar emission amplified and resolved by plasma lensing in an eclipsing binary [PDF]
Nature, 2018 Radio pulsars scintillate because their emission travels through the ionized interstellar medium along multiple paths, which interfere with each other.

Universality of free fall from the orbital motion of a pulsar in a stellar triple system
Nature, 2018Einstein’s theory of gravity—the general theory of relativity1—is based on the universality of free fall, which specifies that all objects accelerate identically in an external gravitational field.

A NEW ELECTRON-DENSITY MODEL FOR ESTIMATION OF PULSAR AND FRB DISTANCES
, 2016We present a new model for the distribution of free electrons in the Galaxy, the Magellanic Clouds, and the intergalactic medium (IGM) that can be used to estimate distances to real or simulated pulsars and fast radio bursts (FRBs) based on their ...
