The prototype Schwarzschild Couder Telescope: A Medium-Sized Telescope for the Cherenkov Telescope Array [PDF]
EPJ Web of ConferencesThe Schwarzschild-Couder Telescope (SCT) is a dual-mirror telescope designed for the Cherenkov Telescope Array Observatory (CTAO) to observe very-high-energy gamma rays (20 GeV to 300 TeV).

The expansion of the Crab Nebula
The Astrophysical Journal, 1991 Using high-resolution radio observations from 1982 and 1987 the expansion of the synchrotron component of the Crab Nebula was measured, including a measurement of the expansion of the nebula's outer edge. The measurements show a rate of expansion similar to that obtained from optical data for the line-emitting filaments.

Spatially Resolved Polarization Variation of the Crab Nebula
The Astrophysical JournalWe examined the spatially resolved polarization variations in the Crab Nebula over 2 yr, using observational data from the Imaging X-ray Polarimetry Explorer, and offer key insights into its magnetic field structures and evolution.

Discovery of TeV gamma-ray emission from the pulsar wind nebula 3C 58 by MAGIC
EPJ Web of Conferences, 2016 The pulsar wind nebula (PWN) 3C 58 is one of the historical very-high-energy (VHE; E>100 GeV) gamma-ray source candidates. It has been compared to the Crab Nebula due to their morphological similarities.

Optical Observations of the Crab Nebula [PDF]
Symposium - International Astronomical Union, 1971 The continuum radiation from the Crab Nebula has a great deal of structure, the majority of which is strongly polarized. Wisps in the vicinity of the pulsar at the centre of the nebula move noticeably in a few months. The appearance of the nebula changes markedly when photographed in different emission lines, as a result of the variations of physical ...

Investigating the Anticorrelation between Photon Index and Flux of the Crab Using RXTE and NuSTAR
The Astrophysical JournalWe present a systematic study of the recently reported anticorrelation between X-ray flux and photon index (Γ) in the Crab Nebula, using archival Rossi X-Ray Timing Explorer (RXTE) Proportional Counter Array (3–50 keV), RXTE High Energy X-ray Timing ...

New constraints on Lorentz Invariance violation from Crab Nebula spectrum beyond 100 TeV
European Physical Journal C: Particles and Fields, 2019 Recently two collaborations, Tibet and HAWC, presented new measurements of gamma-ray spectrum from Crab Nebula (Amenomori et al. in Phys Rev Lett 123(5):051101, 2019, arXiv:1906.05521 [astro-ph.HE]; Abeysekara et al. [HAWC Collaboration] in Astrophys. J.

Future X-ray Polarimetry of Relativistic Accelerators: Pulsar Wind Nebulae and Supernova Remnants
Galaxies, 2018 Supernova remnants (SNRs) and pulsar wind nebulae (PWNs) are among the most significant sources of non-thermal X-rays in the sky, and the best means by which relativistic plasma dynamics and particle acceleration can be investigated.

The Astrophysical JournalThe supernova remnant (SNR) 0540–69.3, twin of the Crab Nebula, offers an excellent opportunity to study the continuum emission from a young pulsar and pulsar wind nebula (PWN). We present observations taken with the Very Large Telescope instruments MUSE
