A new approach to generate a catalogue of potential historical novae
Astronomische Nachrichten, Volume 341, Issue 1, Page 79-98, January 2020., 2020 Abstract Ancient Chinese, Korean, and Vietnamese observers left us records of celestial sightings, the so‐called “guest stars” dated up to ∼2500 years ago. Their identification with modern observable targets could open interesting insights into the long‐term behavior of astronomical objects, as shown by the successful identification of eight galactic ...

PULSAR WIND NEBULAE MODELING [PDF]
International Journal of Modern Physics: Conference Series, 2014 Pulsar Wind Nebulae (PWNe) are ideal astrophysical laboratories where high energy relativistic phenomena can be investigated. They are close, well resolved in our observations, and the knowledge derived in their study has a strong impact in many other fields, from AGNs to GRBs.

, 2011 [[abstract]]Several `exotic' supernova remnants are re-interpreted as pulsar-illuminated former wind-zones. The class of supernova remnants thus splits into (i) (the usual) `shell remnants' and (ii) `pulsar nebulae' in which a (fairly young) pulsar blows

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.

The imprint of pulsar parameters on the morphology of Pulsar Wind Nebulae [PDF]
, 2016 The morphology of young Pulsar Wind Nebulae (PWN) is largely determined by the properties of the wind injected by the pulsar. We have used a recent parametrization of the wind obtained from force-free electrodynamics simulations of pulsar magnetospheres ...

Polarization of Intrabinary Shock Emission in Spider Pulsars
The Astrophysical Journal, 2023 In so-called spider pulsars, the X-ray band is dominated by intrabinary shock (IBS) synchrotron emission. While the double-peaked X-ray light curves from these shocks have been well characterized in several spider systems (both black widows and redbacks),

The Mouse Pulsar Wind Nebula [PDF]
The Astrophysical Journal, 2018 Abstract The young energetic pulsar J1747–2958 (τ = 26 kyr, erg s−1) powers the Mouse pulsar wind nebula (PWN), famous for its spectacular tail spanning 45″ in X-rays and 12′ in radio (d ∼ 5 kpc).

International Astronomical Union Colloquium, 1996 Abstract I discuss pulsar wind nebulae for which ram pressure from the neutron star’s motion is a key element of the morphology. These PWN are tools for determining the pulsar distance, radial velocity component, and interaction of pulsar winds with surrounding media.

EPJ Web of Conferences, 2015 Massive star-forming regions assemble a large number of young stars with remnants of stellar evolution and a very dense environment. Therefore, particles accelerated in supernova remnants and pulsar wind nebulae encounter optimal conditions for ...
