A survey of 380 sq. deg. of the sky with the 1m Schmidt telescope at the Observatorio Nacional de Llano del Halo and the QUEST camera has found 498 RR Lyrae...
We discuss the possibility that the extended structures, lacking young stars, routinely found in dwarf irregular galaxies (dIrr) are a consequence of a...
HAMC2 Astrometry and Photometry calibration and comparison of its data with those of other modern CCD catalogues
The second Hispano-Argentinian Meridian Catalogue (HAMC2) contains more than 12.500.000 positions and magnitudes of stars brighter than V=16.5 and with...
The star 55 Cancri was one of the first known exoplanet hosts and each of the planets in this system is remarkable. Planets b and c are in a near 1:3 resonance...
Hard X-ray-to-radio energy distributions in starburst galaxies
We present in this contribution the predictions on the multiwavelength spectral energy distribution of our evolutionary population synthesis models including...
HARMONI - the Extremely Large Telescope first light integral field spectrograph: pre-optics: stray light analysis
HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 450nm to 2450nm with resolving...
HARMONI at ELT: designing a laser guide star wavefront sensors for the ELT
HARMONI is the first light visible and near-IR integral field spectrograph for the ELT covering a large spectral range from 450nm to 2450nm with resolving...
HARMONI at ELT: mechanisms of the pre-optics at CDR
HARMONI is the first light visible and near-IR integral field spectrograph for the Extremely Large Telescope (ELT). This instrument covers a large spectral...
HARMONI at ELT: opto-mechanics of the IFS pre-optics at CDR
HARMONI is the first light visible and near-IR integral field spectrograph for the Extremely Large Telescope (ELT). It covers a large spectral range from 450nm...
