Etude multilongueur d'onde des pulsars milliseconde

, 2011
Les pulsars milliseconde (MSPs) sont des étoiles à neutrons caractérisées par une période de rotation de l'ordre de la milliseconde. Ils sont très probablement accélérés (recyclés) dans des systèmes binaires par transfert de moment cinétique lors d'une ...

Multifaceted Emission Properties of PSR J2129+4119 Observed with FAST

The Astrophysical Journal
We present a detailed single-pulse study of the long-period pulsar PSR J2129+4119 using high-sensitivity Five-hundred-meter Aperture Spherical Radio Telescope (FAST) observations.

Young radio-loud gamma-ray pulsar light curve fitting

, 2021
International audienceContext. Since the launch of the Fermi gamma-ray telescope, several hundred radio-loud gamma-ray pulsars have been detected, many belonging to millisecond pulsars but some belonging to the young pulsar population with spin periods ...

Identifying Subcomponents of Mean Pulse Profiles of PSR B1822–09 with Single Pulses

The Astrophysical Journal
Using observational data obtained with the Five-hundred-meter Aperture Spherical radio Telescope, we succeeded in identifying subcomponents of different pulse profile components of PSR B1822−09 by the phase-to-phase cross correlations between intensity ...

Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST): A Powerful Explorer of Exotic Pulsars

Universe
Located in southern China, the five-hundred-meter aperture spherical radio telescope (FAST) is the world’s most sensitive radio telescope, especially for pulsar observation. Since its commissioning in 2016 and full operation in 2020, it has detected over

Spectral and rotational properties of radio pulsars

, 2019
This thesis focusses on radio pulsars, rapidly rotating and highly magnetised neutron stars that emit electromagnetic radiation from their magnetic poles.

Radio pulsar variability [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractPulsars are potentially the most remarkable physical laboratories we will ever use. Although in many senses they are extremely clean systems there are a large number of instabilities and variabilities seen in the emission and rotation of pulsars.

On the origins of part-time radio pulsars

, 2007
Growing evidence suggests that some radio pulsars only act sporadically. These 'part-time' pulsars include long-term nulls, quasi-periodic radio flares in PSR B1931+24, as well as the so-called Rotating Radio Transients (RRATs).

Evidence for magnetospheric effects on the radiation of radio pulsars [PDF]

, 2019
We have conducted the largest investigation to date into the origin of phase resolved, apparent RM variations in the polarized signals of radio pulsars.

Detection of Hidden Emissions in Two Rotating Radio Transients with High Surface Magnetic Fields

The Astrophysical Journal Letters
Rotating radio transients (RRATs) are neutron stars emitting sporadic radio pulses. The unique emission of RRATs has been proposed to resemble those of known pulsar types, such as extreme nulling pulsars or pulsars with giant pulses.
