An Optimized H_β Index for Disentangling Stellar Clusters and Galaxy Ages
We have derived a new H_{β} absorption index definition, which is fully optimized as an age indicator for old and intermediate-aged stellar populations. Rather...
An Overview of the Bowen Survey: Detecting Donor Star Signatures in Low Mass X-ray Binaries
In this paper we give a review of the Bowen fluorescence survey, showing that narrow emission lines (mainly N III and C III lines between 4630 and 4660 A˚)...
An Overview of the MOS Capabilities of the 4-10 m Telescopes at La Palma Observatory for Investigating Galaxy Clusters
La Palma Observatory offers four multi-object spectrographs installed on 4 and 10 m class telescopes. We present an overview of these four instruments. As a...
An overview of the preliminary optical design of the European Solar Telescope (EST)
The European Solar Telescope (EST) is a 4-m class-solar telescope that will become part of the next generation of groundbased facilities. Located at the...
An Unbiased Survey of X-ray and Optical Emission from Extended Radio Jets in AGN with Chandra and HST
The Chandra discovery of an X-ray bright jet in the "first light" distant quasar PKS 0637-752 showed that the X-rays can be energetically dominant even at large...
