Collisionless shock waves in supernova remnants and the solar wind heat electrons less
effectively than they heat ions, as is predicted by kinetic simulations. However, the values of …

Some active galactic nuclei (AGN) are surrounded by extended emission-line regions
(EELRs), which trace both the illumination pattern of escaping radiation and its history over …

New optical spectrophotometric data are presented for the supernova remnants CTB 1, OA
184, VRO 42.05. 01, S147, the Monoceros Loop, G206. 9+ 2.3, and G65. 3+ 5.7. These data …

We present an observational and theoretical study of the optical emission from nonradiative
shocks in three supernova remnants: the Cygnus Loop, RCW 86, and Tycho. The spectra of …

Radiation shock waves are shown to be organizable into families within which the spectra
are very similar. A high-velocity shock into neutral material is spectrally similar to a …

A new theoretical analysis of the structure of interstellar shocks and the grain dynamics of
these shocks is presented. The basic hydrodynamic equations for J-shocks in interstellar …

A leading stellar astronomer summarizes our understanding of supernovae and their
interaction with interstellar gas, including the ambient interstellar medium, the gas ejected in …

A comparison is made of optical and UV line intensities and spatial and spectral optical line
profiles of a well-defined Cygnus Loop filament with theoretical models. It is found that the …

We present a complete atlas of the Cygnus Loop supernova remnant in the light of [O III](λ
5007), H α, and [S II](λ λ 6717, 6731). We include low-resolution (25 &arcsec;) global maps …

A sheet description of the emission from middle-aged supernova remnants ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …
