Overcoming the Challenges of Transmural Durable Lesions With PFA-Impact of Electrode Design and Contact Assessment. [PDF]

open access: yesPacing Clin Electrophysiol
Abstract Electrode design and reliable contact assessment are critical for creating durable pulsed field ablation (PFA) lesions to treat atrial fibrillation while minimizing collateral damage. This review introduces a novel “map‐and‐ablate” PFA catheter featuring flat electrodes, thermal contact assessment, and fully customizable electrode selection ...

Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]

open access: yesAdv Sci (Weinh)
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

SOME EVOLUTIONARY ASPECTS OF THE BINARY STELLAR SYSTEMS CONTAINING NEUTRON STAR

open access: yesOdessa Astronomical Publications, 2012
The obvious lack of the binary stellar systems that contain neutron stars (NS) is observed at present. Partly it is caused by the fact that it is very difficult to detect neutron star in a binary system if this relativistic component does not manifest ...

Binary and Millisecond Pulsars

open access: yesLiving Reviews in Relativity, 2008
We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar ...

Algorithmic Pulsar Timer for Binaries

open access: yesThe Astrophysical Journal
Pulsar timing is a powerful tool that, by accounting for every rotation of a pulsar, precisely measures the spin frequency, spin frequency derivatives, astrometric position, binary parameters when applicable, properties of the interstellar medium, and ...

Gravity experiments with radio pulsars

open access: yesLiving Reviews in Relativity
The discovery of the first pulsar in a binary star system, the Hulse–Taylor pulsar, 50 years ago opened up an entirely new field of experimental gravity.

The Confrontation between General Relativity and Experiment

open access: yesLiving Reviews in Relativity, 2006
The status of experimental tests of general relativity and of theoretical frameworks for analyzing them is reviewed. Einstein’s equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of special relativity, and ...

Binary and Millisecond Pulsars [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 1994
Most of the ~600 known pulsars are single and located in the disk of our Galaxy. There is circumstantial evidence that the pulsars in this majority are created in supernova (SN) explosions, by the collapse of the cores of massive stars (initial mass M_i ≳ M_(cr) ≃ 8 M_⊙). One is created roughly every 100 y in the Galaxy.

A Light Redback Companion of PSR J1622–0315 and Irradiation Power in Spider Systems

open access: yesThe Astrophysical Journal, 2023
We report optical observations of the millisecond pulsar binary system PSR J1622–0315 with the Lulin 1 m telescope in Taiwan and the Lijiang 2.4 m telescope in China between 2019 and 2021.
