How Normal Disk Galaxies Ionize their Surroundings
We examine using numerical examples and conservative assumptions, the consequences of the fractal structure of the interstellar medium in a disk galaxy in...
How Planetary Nebulae Shells Interact with their Local Environement
Planetary Nebula (PN) shells and AGB circumstellar envelopes evolve under a wide range of external conditions, from the high ISM densities found in the Galactic...
We present here the outline of the process that any potential GTC observer will need to follow in order to perform their observations. Depending on which of the...
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...
