Descripción
We have completed a survey of early-type galaxies in a region covering 700 sq. degrees with cz<7000km/s. We find no early-type galaxies with MB > -20 that satisfy our isolation criteria. The sample galaxies obey the Mg-sigma relation but have a higher frequency of [OII] and [OIII] emission than found in the Fornax cluster. They appear to be younger than the ellipticals in the Fornax cluster having a spread in luminosity weighted ages similar to lenticular galaxies. This work was funded by the PPARC rolling grant: ``Extragalactic Astronomy and Cosmology in Durham 2000-2004'' PPA/G/O/1999/00604.

    Design and manufacture of athermalized optomechanical mounts for GRANCAIN, the infrared imaging instrument for GTC's adaptive optics
    GRANCAIN (GRAN CAmara INfrarroja) is a first-light imaging instrument in the infrared J, H and K bands that will be integrated into the adaptive optics focus of the Gran Telescopio de Canarias. The purpose of the instrument is to capture SWIR diffraction-limited images for a field of view of 22x22 arcsec. The instrument boasts a telecentric optical

    Optical coating facilities at the Instituto de Astrofísica de Canarias
    The Instrumentation Division of the Instituto de Astrofísica de Canarias (IAC) is involved since several years in upgrading its capacities to design and manufacture optical components. To this end, we have created a new laboratory (Centre for Advanced Optical Systems, CSOA) which will be capable to design, fabricate and qualify large optical

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
