recommendations! Published in 2021 at "Astronomy and Astrophysics"

DOI: 10.1051/0004-6361/202039278

Abstract: Context. We have presented a numerical model for the non-thermal emission of gamma-ray binaries in a pulsar-wind driven scenario. Aims. We apply this model to one of the best-observed gamma-ray binaries, the LS 5039 system.… read more here.

DOI: 10.1093/mnras/staa016

Abstract: The next era of ground-based Cherenkov telescope development will see a great increase in both quantity and quality of $\gamma$-ray morphological data. This initiated the development of a spatio-temporal leptonic transport code to model pulsar… read more here.

DOI: 10.1093/mnras/staa3039

Abstract: SNR G0.9+0.1 is a well known source in the direction of the Galactic Center composed by a Supernova Remnant (SNR) and a Pulsar Wind Nebula (PWN) in the core. We investigate the potential of the… read more here.

DOI: 10.1093/mnras/stae1300

Abstract: We present the description and initial results of the TRAPUM (TRAnsients And PUlsars with MeerKAT) search for pulsars associated with supernova remnants (SNRs), pulsar wind nebulae and unidentified TeV emission. The list of sources to… read more here.

recommendations! Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty2525

Abstract: When a pulsar is moving through a partially ionized medium, a fraction of neutral Hydrogen atoms penetrate inside the pulsar wind and can be photo-ionized by the nebula UV radiation. The resulting protons remains attached… read more here.

DOI: 10.1093/mnras/stz213

Abstract: Bow-shock pulsar wind nebulae (PWNe) show a variety of morphological shapes. We attribute these variations to the intrinsic properties (relative orientation of the pulsar's spin, velocity, and magnetic inclination angle) - as well as the… read more here.

DOI: 10.1093/mnras/stz3270

Abstract: CTB 87 (G74.9+1.2) is an evolved supernova remnant (SNR) which hosts a peculiar pulsar wind nebula (PWN). The X-ray peak is offset from that observed in radio and lies towards the edge of the radio… read more here.

DOI: 10.1093/ptep/ptae069

Abstract: Pulsar wind nebulae (PWNe) are clouds of the magnetized relativistic electron/positron plasma supplied from the central pulsar. However, the number of radio-emitting particles inside a PWN is larger than the expectation from the study of… read more here.
