As a sub-set of activities within the THINGS (The HI Nearby Galaxy Survey) collaboration we have used the HI maps of the complete set of galaxies observed in the THINGS survey with the VLA to search for the presence of high velocity clouds. Detections were made in 9% of the cases, with a lower detection limit of just under 105 solar masses. Given

SPIRE, the Spectral and Photometric Imaging Receiver, is a submillimetre camera and spectrometer for Herschel. It comprises a three-band camera operating at 250, 350 and 500 µm, and an imaging Fourier Transform Spectrometer covering 194-672 μm. The photometer field of view is 4x8 arcmin., viewed simultaneously in the three bands. The FTS has an

We present a short summary of the activities developed by GUAIX, the UCM Group of Instrument and Extragalactic Astrophysics. At present we are focused in the development of data reduction pipelines for three future instruments for the Spanish 10~m GTC (Gran Telescopio Canarias). The careful treatment of the random error propagation throughout the

GHαFaS is a new Fabry-Perot system available at the William Herschel Telescope. It was mounted, for the first time, at the Nasmyth focus of the 4.2 m WHT in La Palma in 2007 July. With a spectral resolution of the order R~15000 and a seeing limited spatial resolution, GHαFaS provides a new look at the Hα-emitting gas over a 4 arcminutes circular

GD 552 is a high proper motion star with the strong, double-peaked emission lines characteristic of the dwarf nova class of cataclysmic variable (CV) star, and yet no outburst has been detected during the past 12yr of monitoring. We present spectroscopy taken with the aim of detecting emission from the mass donor in this system. We fail to do so at

As part of an optical monitoring project of low-mass X-ray binaries (
