High-Energy Processes in Young Stellar Objects
TL;DR: In the early stages of the evolution of low-mass stars, from protostars through the zero-age main sequence, magnetic reconnection flares are seen in the X-ray and radio bands.

ASCA Observations of Seyfert 1 Galaxies. III. The Evidence for Absorption and Emission Due to Photoionized Gas
Ian M. George,Ian M. George,T. J. Turner,T. J. Turner,Hagai Netzer,K. Nandra,Richard Mushotzky,Tahir Yaqoob,Tahir Yaqoob +8 more
TL;DR: In this article, a detailed analysis of the 0.6-10 keV spectra of 23 ASCA observations of 18 objects was carried out and the importance of the covering fraction of the ionized gas and a direct comparison between models of attenuation by ionized versus neutral material was made.
Journal ArticleDOI
Clusters of galaxies
TL;DR: In this article, a review of properties of clusters of galaxies and some theoretical interpretations are reviewed, including catalogs of clusters, the static properties of rich clusters, cluster dynamics, X-ray emission from clusters, and cluster radio emission.
Journal ArticleDOI
X-ray properties of groups of galaxies
TL;DR: In this paper, a combination of thermal bremsstrahlung and line emission was found to be the most likely mechanism for the X-ray emission in groups of galaxies, where the entire volume of groups was filled with a hot, low-density gas known as the intragroup medium.

TL;DR: The very high energy (VHE) gamma rays with energy > 300 GeV were detected from this object with a time-averaged integral flux of (4.2 +/- 0.7 (stat) +/- 2.0 (sys)) x 10^(-11) per cm2 per s.
