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...
HST-NICMOS Observations of Galactic Bulges: Red Nuclei in Nearby Galaxies
We describe multi-color observations with NICMOS and WFPC2 of 20 nuclei of nearby galactic bulges of types S0-Sbc. We find that the centers of 19 out of 20...
HST/NICMOS Photometry of M31's Bulge and Metal-Rich Globular Clusters
We have obtained JHK images of 5 bulge fields and 5 metal-rich globular clusters in M31 with the NICMOS camera NIC2 on the Hubble Space Telescope. The globulars...
Hunting Exoplanets with Single-Mode Optical Interferometry
The GRAVITY instrument was primarily conceived for imaging and astrometry of the Galactic centre. However, its sensitivity and astrometric capabilities have...
