XMM-Newton and Chandra Observations of the Candidate Fermi-LAT Pulsar 4FGL J1015.5-6030
The Astrophysical Journal, 2023 4FGL J1015.5-6030 is an unidentified Fermi-LAT source hosting a bright, extended X-ray source whose X-ray spectrum is consistent with that of a young pulsar, yet no pulsations have been found.

Gigahertz-peaked spectra pulsars in Pulsar Wind Nebulae [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We have carried out a detailed study of the spectral nature of six pulsars surrounded by Pulsar wind nebulae (PWN). The pulsar flux density were estimated using the interferometric imaging technique of the Giant Metrewave Radio Telescope at three frequencies 325 MHz, 610 MHz and 1280 MHz. The spectra showed a turnover around gigahertz frequency in four

Radio Study of the Pulsar Wind Nebula Powered by PSR B1706-44
The Astrophysical Journal, 2023 PSR B1706−44 is an energetic gamma-ray pulsar located inside supernova remnant (SNR) G343.1−2.3 and it powers a compact pulsar wind nebula (PWN) that shows torus and jet structure in X-rays.

Particle acceleration in Pulsars and Pulsar Wind Nebulae
, 2022 These notes summarise the contents of the lectures I delivered at the International School of Physics "Enrico Fermi" on "Foundations of Cosmic Ray Astrophysics". The lectures were dealing with the physics of Pulsars and Pulsar Wind Nebulae (PWNe) in the Cosmic Ray (CR) perspective.

Neutrinos from the pulsar wind nebulae [PDF]
Astronomy & Astrophysics, 2003 In the recent paper we calculated the $ $-ray spectra from pulsar wind nebulae (PWNe), assuming that a significant amount of the pulsar rotational energy is converted into relativistic nuclei. These nuclei accelerate leptons which are responsible for most of the observed electromagnetic emission from PWNe.

X-RAY EVOLUTION OF PULSAR WIND NEBULAE [PDF]
The Astrophysical Journal, 2010 During the search for counterparts of very-high-energy gamma-ray sources, we serendipitously discovered large, extended, low surface brightness emission from PWNe around pulsars with the ages up to ~100 kyrs, a discovery made possible by the low and stable background of the Suzaku X-ray satellite.

MHD Interaction of Pulsar Wind Nebulae with SNRs and the ISM [PDF]
, 2005 In the late 1960s the discovery of the Crab pulsar in its associated supernova remnant, launched a new field in supernova remnant research: the study of pulsar-driven or plerionic supernova remnants. In these type of remnants, the relativistic wind emitted by the pulsar, blows a pulsar wind nebula into the interior of its supernova remnant.
