How to use the SEDs produced by synthesis models (inside and outside the VO)?
In this contribution we investigate how to describe the results and usage of evolutionary synthesis models. In particular, we look for an explicit and...
HST emission line images of the Orion HII region: proper motions and possible variability
The Orion Nebula (NGC 1976, M42) contains the nearest massive star forming region and is therefore ideal for studying the physical process accompanying star...
According to unified schemes for blazars, BL Lac objects are dominated by relativistic jets pointing along the line of sight. Their plane-of-the-sky...
