We report here the first results of a program aimed at obtaining high signal to noise (up to ~ 500) optical spectroscopy of a large sample of BL Lac objects...
WEAVE: The next generation wide-field spectroscopy facility for the WHT
I will describe the major scientific motivation and outline design concept for a new 2 degree field, 1000 fibre multi-object spectroscopy facility for the WHT...
What can near-ultraviolet spectroscopy tell us about the final moments of supernova progenitors?
The fate of massive stars and the type of supernova (SN) they produce are closely linked to their final stages of evolution. During these late phases, stars may...
WSO and the winds of massive stars: the gate to the metal-poor Local Universe
The spectrographs on-board the World Space Observatory (WSO) will provide access to the 1020-1800 Å wavelength range with unprecedented sensitivity. Previous...
We present the first release of XSL, the X-Shooter Spectral Library observed at the European Southern Observatory (ESO). This release contains 237 stars...
