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 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...
Three of the best determinations of the primordial helium abundance (Yp) are those obtained from low metallicity HII regions by Aver, Olive, Porter, & Skillman...
We are reporting the updates in version 0.2.0 of the Automated SpectroPhotometric REDuction (ASPIRED) pipeline, designed for common use on different instruments...
An upper limit to the Beryllium abundance in the population 2 star HD 140283 from a high resoluion IUE spectrum
An IUE archive spectrum of HD 140283 has been analyzed in the region of the 3131 Å 9Be II resonance doublet. Close comparison of the observed and synthetic...
