Timing stability of three black widow pulsars [PDF]

, 2020
International audienceWe study the timing stability of three black widow pulsars (BWPs), both in terms of their long-term spin evolution and their shorter term orbital stability.

Discovering pulsars with machine learning

, 2016
Pulsars are compact and fast-spinning stars whose unique properties allow us to probe the laws of Physics in truly extreme conditions and to put Einstein’s General Relativity to the test. New pulsars are usually discovered with a radio telescope, but the

General-relativistic pulsar magnetospheric emission [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
Most current pulsar emission models assume photon production and emission within the magnetosphere. Low frequency radiation is preferentially produced in the vicinity of the polar caps whereas the high-energy tail is shifted to regions closer but still inside the light-cylinder.

High magnetic field pulsars and magnetars: A unified picture

, 2000
We propose a unified picture of high magnetic field radio pulsars and magnetars by arguing that they are all rotating high-field neutron stars but that their magnetic axes have different orientations with respect to their rotation axes.

Generation of relativistic particles in pulsar magnetospheres

, 2012
The problem - fundamental for the physics of pulsars - of determining the global structure of the magnetosphere in a self-consistent way has not yet been solved satisfactorily. We report on some progress in this direction, which we have achieved by studying the trajectories of individual charged particles in the electromagnetic vacuum fields of an ...

Gravitational science with pulsars and the square kilometre array

, 2009
Pulsar observations form one of the Key Science Projects for the Square Kilometre Array. These will allow unique tests of General Relativity based on finding and timing pulsars in relativistic binaries and on timing millisecond pulsars distributed across

Signals of the QCD Phase Transition in the Heavens

, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

PULSARS: GIGANTIC NUCLEI

, 2011
What is the real nature of pulsars'? This is essentially a question of the fundamental strong interaction between quarks at low-energy scale and hence of the non-perturbative quantum chromo-dynamics, the solution of which would certainly be ...
