Custom Components and Library Packages,the EUV flux is, in fact, composed partly of line emission, we consider the implications if this is the result of emission from a collision-driven plasma at temperatures ? 10. K. In this context, we discuss some of the constraints imposed on the emission-line region by this observation.

Developing the Message Display Moduleut the possibility that the EUV emission is from a diffuse corona or intercloud medium. Models that assume the soft X-ray/EUV emission results from reprocessing in an optical BLR region are also inconsistent with the data. A collisional excitation model is consistent with the observations but requires a cloud density ≥ 10. cm..

Behind the Scenes II: MySQL and Data Storage are discussed. The importance of the geometry adopted when interpreting the emission measure distribution is stressed, since radial factors can lead to an . emission measure distribution gradient that is steeper than the value of 3/2 expected in plane parallel geometry.

Active Galactic Nuclei in the Extreme Ultraviolet objects, have already been identified, and spectroscopic measurements of several of them have yielded a number of surprises. However, more observations are clearly needed to confirm some of the reported spectral features and to validate their interpretation.

Line Emission from Warm Material in NGC 5548 region. A fit to a thermal plasma yields a temperature of 6 × 10. K. The line emission can be attributed to the warm absorbing material discovered before from oxygen and iron absorption features, which appears to be an optically thin (for the Lyman continuum), highly ionized phase of the broad-line region.
