Relativistic rotating vector model for X-ray millisecond pulsars [PDF]

open access: yesAstronomy & Astrophysics, 2020
The X-ray radiation produced on the surface of accreting magnetised neutron stars is expected to be strongly polarised. A swing of the polarisation vector with the pulsar phase gives a direct measure of the source inclination and magnetic obliquity.

Defining Millisecond Pulsars

open access: yesResearch Notes of the AAS, 2023
Abstract Millisecond pulsars (MSP) are an important subclass of rotation powered pulsars (RPP), traditionally defined as those with P s  < 20–30 ms and B s  ≲ 1010 G.

Dispersion measure variability for 36 millisecond pulsars at 150 MHz with LOFAR [PDF]

open access: yesAstronomy & Astrophysics, 2020
Context. Radio pulses from pulsars are affected by plasma dispersion, which results in a frequency-dependent propagation delay. Variations in the magnitude of this effect lead to an additional source of red noise in pulsar timing experiments, including ...

Message in a Bottle—An Update to the Golden Record: 1. Objectives and Key Content of the Message

open access: yesEarth and Space Science, Volume 10, Issue 12, December 2023., 2023
Abstract In the first part of this series, we delve into the foundational aspects of “Message in a Bottle (MIAB)” (henceforth referred to as MIAB). This study builds upon the legacy of the Voyager Golden Records, launched aboard Voyager 1 and 2 in 1977, which aimed to communicate with intelligent species beyond our world. These records not only offer a

Fit‐Fat Index is better associated with heart rate variability compared to fitness and fatness alone as indicators of cardiometabolic human health

open access: yesAmerican Journal of Human Biology, Volume 35, Issue 11, November 2023., 2023
Abstract Objectives Cardiorespiratory fitness and fatness indicators have been related to heart rate variability (HRV) parameters. The Fit‐Fat Index (FFI) is a single index combining cardiorespiratory fitness and fatness indicators. To the best of our knowledge, no studies have previously analyzed whether FFI are related to cardiac autonomic nervous ...

Structure and stability of differentially rotating compact stellar objects

open access: yesAstronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023
Abstract Depending on the dynamics of a binary neutron star merger, the collision may result in a differentially rotating compact object. Differentially rotating stars can sustain a total mass considerably higher than that of a uniformly rotating star, giving rise to “hypermassive” objects like hypermassive neutron stars.

Search for the Gravitational-wave Background from Cosmic Strings with the Parkes Pulsar Timing Array Second Data Release

open access: yesThe Astrophysical Journal, 2022
We perform a direct search for an isotropic stochastic gravitational-wave background (SGWB) produced by cosmic strings in the Parkes Pulsar Timing Array (PPTA) Data Release 2 (DR2).

The NANOGrav 12.5 yr Data Set: Observations and Narrowband Timing of 47 Millisecond Pulsars

open access: yesAstrophysical Journal Supplement Series, 2020
We present time-of-arrival (TOA) measurements and timing models of 47 millisecond pulsars observed from 2004 to 2017 at the Arecibo Observatory and the Green Bank Telescope by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav ...
