A newly discovered VHE gamma-ray PWN candidate around PSR J1459-60

TL;DR

This paper reports the discovery of a new very-high-energy gamma-ray source near PSR J1459-60, suggesting a pulsar wind nebula, based on H.E.S.S. observations and multi-wavelength analysis.

Contribution

It presents the first detection and analysis of a VHE gamma-ray source associated with PSR J1459-60, proposing a PWN scenario for the emission.

Findings

Detection of significant VHE gamma-ray excess near PSR J1459-60

Morphological and spectral characterization of the gamma-ray source

Discussion of PWN association with the pulsar

Abstract

Observations of the Galactic Plane performed by the H.E.S.S. telescope array have revealed a significant excess at very-high-energies (VHE; E>0.1 TeV) from the direction of PSR J1459-60, a rather old gamma-ray pulsar (64 kyr) with a spindown energy of ~10^36 erg/s, discovered by the Fermi/LAT satellite in high-energy (HE) gamma-rays. The X-ray pulsar counterpart has been recently detected using the Suzaku satellite. In this contribution, we present the discovery of a new VHE gamma-ray source, including morphological and spectral analyses. Its association with the gamma-ray pulsar in a PWN scenario will be discussed.
