BlackHoleCam — Testing general relativity with pulsars orbiting Sagittarius A

open access: yesThe Fifteenth Marcel Grossmann Meeting, 2022
BlackHoleCam is a project funded by a European Research Council Synergy Grant to build a complete astrophysical description of nearby supermassive black holes by using a combination of radio imaging, pulsar observations, stellar astrometry and general relativistic magneto-hydrodynamic models.

Pulsar magnetospheres in general relativity [PDF]

open access: yesPhysical Review D, 2018
The main contribution to the pulsar power can be calculated by assuming a rotating magnetically-dominated magnetosphere described by the force-free approximation. Although this simple model has been used thoroughly to study pulsar magnetospheres in the flat spacetime regime, only few works have considered the relativistic corrections introduced by the ...

Generative pulsar timing analysis [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
A new Bayesian method for the analysis of folded pulsar timing data is presented that allows for the simultaneous evaluation of evolution in the pulse profile in either frequency or time, along with the timing model and additional stochastic processes such as red spin noise, or dispersion measure variations. We model the pulse profiles using `shapelets'

Recycled Pulsars [PDF]

open access: yes, 2005
We present the results of a large-area survey for millisecond pulsars (MSPs) at moderately high galactic latitudes with the 64 m Parkes radio telescope, along with follow-up timing and optical studies of the newly-discovered pulsars and several others ...

Radio Pulsars Resonantly Accelerating Electrons

open access: yes, 2023
Based on the recently demonstrated resonant wave–wave process, it is shown that electrons can be accelerated to ultra-relativistic energies in the magnetospheres of radio pulsars. The energization occurs via the resonant interaction of the electron

Pulsars and their genesis

open access: yes, 1986
Recent research on the nature of pulsars and the reasons for their formation is reviewed. The magnetospheres of pulsars are discussed, and the significance of binary stars for the genesis of pulsars is addressed.

A Bayesian method for pulsar template generation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Extracting Times of Arrival from pulsar radio signals depends on the knowledge of the pulsars pulse profile and how this template is generated. We examine pulsar template generation with Bayesian methods. We will contrast the classical generation mechanism of averaging intensity profiles with a new approach based on Bayesian inference. We introduce the
