Shocking Clouds in the Cygnus Loop
With Hubble Space Telescope Wide-Field Planetary Camera 2 observations of the Cygnus Loop supernova remnant, we examine the interaction of an interstellar cloud with the blast wave on physical scales of 10 cm. The shock front is distorted, revealing both edge-on and face-on views of filaments and diffuse emission, similar to those observed on larger scales at lower resolution. We identify indiv...
متن کاملPanoramic Views of the Cygnus Loop
We present a complete atlas of the Cygnus Loop supernova remnant in the light of [O III] (λ5007), Hα, and [S II] (λλ6717, 6731). We include low-resolution (25) global maps and smaller fields at 6 resolution from observations using the Prime Focus Corrector on the 0.8-m telescope at McDonald Observatory. Despite its shell-like appearance, the Cygnus Loop is not a current example of a Sedov-Taylo...
متن کاملNew λ 6 cm observations of the Cygnus Loop
Radio continuum and polarization observations of the entire Cygnus Loop at λ6 cm wavelength were made with the Urumqi 25 m telescope. The λ6 cm map is analysed together with recently published maps from the Effelsberg 100 m telescope at λ21 cm and λ11 cm. The integrated flux density of the Cygnus Loop at λ6 cm is 90±9 Jy, which implies a spectral index of α = −0.40 ± 0.06 being consistent with ...

‘O. what a world of unseen visions and heard silences, this insubstantial country of the mind! What ineffable essences, these touchless rememberings and unshowable reveries! And the privacy of it all! A secret theatre of speechless monologue and prevenient counsel, an invisible mansion of all moods, musings, and mysteries, an infinite resort of disappointments and discoveries. A whole kingdom w...
متن کامل4 Environmental Impact on the Southeast Limb of the Cygnus Loop
We analyze observations from the Chandra X-ray Observatory of the southeast knot of the Cygnus Loop supernova remnant. In this region, the blast wave propagates through an inhomogeneous environment. Extrinsic differences and subsequent multiple projections along the line of sight rather than intrinsic shock variations, such as fluid instabilities, account for the apparent complexity of the imag...
