Disentangling multiple high-energy emission components in the Vela X pulsar wind nebula with the Fermi Large Area Telescope [PDF]
Astronomy & Astrophysics, 2018 Context. Vela X is a pulsar wind nebula in which two relativistic particle populations with distinct spatial and spectral distributions dominate the emission at different wavelengths. An extended 2° × 3° nebula is seen in radio and GeV gamma rays.

Erratum: Modelling the ArH+ emission from the Crab Nebula [PDF]
Monthly notices of the Royal Astronomical Society, 2017 We have performed combined photoionization and photodissociation region (PDR) modelling of a Crab Nebula filament subjected to the synchrotron radiation from the central pulsar wind nebula, and to a high flux of charged particles; a greatly enhanced ...

The PAH Emission Characteristics of the Reflection Nebula NGC 2023 [PDF]
, 2017 We present 5–20 μm spectral maps of the reflection nebula NGC 2023 obtained with the Infrared Spectrograph SL and SH modes on board the Spitzer Space Telescope, which reveal emission from polycyclic aromatic hydrocarbons (PAHs), C60, and H2 superposed on

Observing and Modeling the Gamma-Ray Emission from Pulsar/Pulsar Wind Nebula Complex PSR J0205+6449/3C 58 [PDF]
, 2017 We present the results of the analysis of eight years of Fermi-LAT data of the pulsar/pulsar wind nebula complex PSR J0205+6449/3C 58. Using a contemporaneous ephemeris, we carried out a detailed analysis of PSR J0205+6449 both during its off-peak and on-

The Antares emission nebula and mass loss of α Scorpii A [PDF]
, 2008 Aims. The Antares nebula is a peculiar emission nebula seen in numerous [Fe ii] lines and in radio free-free emission, probably associated with the H ii region caused by α Sco B in the wind of α Sco A. High-resolution spectra with spatial resolution were

M 1–92 Revisited: New Findings and Open Questions: New NOEMA Observations of Minkowski’s Footprint
Galaxies, 2022 PN M 1–92, also known as Minkowski’s Footprint, is a textbook example of a massive pre-planetary nebula. It presents all the characteristics of this type of source: non-spherical symmetry (bipolar cylindrical symmetry in this case), high-velocity gas ...

A Spatially Resolved X-Ray Polarization Map of the Vela Pulsar Wind Nebula
The Astrophysical Journal Letters, 2023 In this paper, we present a full spatially resolved polarization map for the Vela pulsar wind nebula (PWN) observed by IXPE. By employing effective background discrimination techniques, our results show a remarkably high degree of local polarization in ...
