Highlights of Astronomy, 1968 It seems hard to realise, today, that pulsars were totally unknown at the time of the last General Assembly. The discovery of pulsars dates from November 28th, 1967, when the first pulses were recorded from the source now known as CP 1919. Since then we have witnessed an astonishing phase of activity, amongst observers and theoreticians alike, which ...

Search for a Correlation Between Radio Giant Pulses and VHE Photons of the Crab Pulsar
Acta Polytechnica, 2011 The Crab pulsar is a unique source of pulsar radio emission. Its regular pulse structure is visible over the entire electromagnetic spectrum from radio to GeV ranges.

Comprehensive Measurement of Position and Velocity in the Transverse Direction Using the Crab Pulsar
AerospaceTraditional X-ray pulsar ranging and velocity measurement methods only estimate the radial position and velocity information of the pulsar. For non-linear orbits, errors in the transverse position and velocity of the pulsar lead to errors in the radial ...

Propagation of X-ray and gamma ray emissions in strong magnetic and gravitational fields
Physical Sciences and Technology, 2016 We consider the propagation of X-ray and gamma ray emissions in strong magnetic and gravitational fields of the pulsar in nonlinear vacuum electrodynamics. We show that the radiation has birefrigence.

Frontiers in OncologyFractionated radiotherapy was established in the 1920s based upon two principles: (1) delivering daily treatments of equal quantity, unless the clinical situation requires adjustment, and (2) defining a specific treatment period to deliver a total dosage.

On the overall properties of young neutron stars: an application to the Crab pulsar
Frontiers in Astronomy and Space SciencesIn this brief report, we present a model that complements the well-established canonical model for the spin evolution of rotation-powered pulsars, which is typically used to estimate ages, spin-down luminosity, and surface magnetic fields of middle-aged ...

Serendipitous Discovery of a 431 ms Pulsar in the Background of Westerlund 1
UniverseWe report the discovery of PSR J1646−4545, a 431 ms isolated pulsar, in the direction of the young massive cluster Westerlund 1. The pulsar was found in data taken between the years 2005 and 2010 with the “Murriyang” Parkes radio telescope in Australia ...

Identifying Companions in Pulsar Binary Systems via Gaia Data
UniverseIn the optical band, very few pulsars can be directly detected, but some of the pulsar binary companions can be observed. This study leverages high-precision astrometric data from Gaia Data Release 3 (DR3) to identify pulsar companions in binary systems.
