We use UVES spectroscopy of PB 6 to study the variation of its physical conditions as a function of position including: temperature, density, chemical...
High-resolution transmission spectroscopic studies of hot and ultra-hot Jupiters.
Hot and ultra-hot Jupiters, gas-giant planets with short orbital period, and hot, extended atmospheres, are most suitable objects in order to study the chemical...
The rapidly variable Seyfert 1 galaxy NGC 4151 will be the subject of an intensive monitoring campaign with IUE, Rosat, GRO, ASCA and ground-based telescopes in...
High-Velocity Gas in the Luminous H II Regions of NGC 1530
We are carrying out a systematic study of the ensuremath {{H}alpha } emission line profiles from the H II regions in NGC 1530 (Knapen et al. 2001) based on a...
High-velocity outflows in post-Main-Sequence nebulae
Observations of three post-Main-Sequence nebulae, taken with an intermediate dispersion spectrograph mounted on the 2.5 m Isaac Newton Telescope (La Palma...
We have conducted a survey aimed at identifying a sample of z˜7-10 candidates accessible to detailed spectroscopic studies. The deep survey on A2667 covers a...
