I present results of a high-resolution imaging survey of barred S0--Sa galaxies which show that the central regions of these galaxies are surprisingly complex, and often dominated by dynamically cool components. In particular, inner bars --- secondary, small-scale bars (typically less than a kiloparsec in radius) located inside of, and probably

We report on an ongoing study of disk galaxy merger simulations and their implications for the Fundamental Plane (FP) of elliptical galaxies.

EMIR (Espectrografo Multiobjeto Infrarrojo) is a near-infrared wide-field camera and multi-object spectrograph to be built for the 10.4m Spanish telescope (Gran Telescopio Canarias, GTC) at La Palma. The Data Reduction Pipeline (DRP), which is being designed and built by the EMIR Universidad Complutense de Madrid group, will be optimized for

This contribution reports the status of the Cosmic Microwave Background (CMB) experiments on Tenerife. These include the classic Tenerife beam-switching experiments at 10, 15 and 33 GHz, the Jodrell-IAC interferometer at 33 GHz, the COSMOSOMAS project and the Cambridge-IAC Very Small Array (VSA).

A new empirical model that accurately describes the inner and outer light-profiles of early-type galaxies is presented. This model effectively unites the Sérsic and Nuker models, and in so doing allows one to perform meaningful comparisons between the inner and outer properties of early-type galaxies. New and fundamental connections between a

We present a study of the properties of radial conformal Killing fields (RCKF) in conformally flat space-times, pointing out its interest in kinematical cosmology. i) Robertson-Walker space-times are characterized as those conformally flat metrics admitting a geodesic RCKF. ii) The conformal factor of space-times that admit a RCKF with homogeneous
