The near-UV NH3360 feature has been measured in a sample of 35 early-type galaxies spanning a wide range of masses and environments. We found that, contrary to...
The CODEX-ESPRESSO experiment: Cosmic dynamics, fundamental physics, planets and much more...
CODEX, a high resolution, super-stable spectrograph to be fed by the E-ELT, the most powerful telescope ever conceived, will for the first time provide the...
The cometary contribution to planetary impact rates
We use statistics on the nuclear magnitudes of Jupiter Family comets to derive the number of km-sized members with perihelion distances less than 2 AU. When...
New narrow band images of NGC 4151, taken in excellent seeing conditions with the 4.2-m William Herschel Telescope on La Palma are presented. These reveal a...
The complexity of the coronal line region in AGNs: Gas-jet interactions and outflows revealed by NIR spectroscopy
Apart from the classical broad line region (BLR) at small core distances, and the extended classical narrow-line region (NLR), a subset of active galactic...
Constellation-X presents a great leap forward in collecting area over current X-ray observatories and will enable high signal-to-noise studies of X-ray sources...
