We analyze spectropolarimetric observations of the penumbra of the NOAA AR 10953 at high spatial resolution (0.3 ″ ). The full Stokes profiles of the Fe i lines at 630.1 nm and 630.2 nm have been obtained with the Solar Optical Telescope (SOT) on board the Hinode satellite. The data have been inverted by means of the SIR code, deriving the

We describe the design of the near UV filter imager SuFi onboard Sunrise, which was successfully flown in the stratosphere in June 2009. During its five days flight SuFI captured the highest contrast images of solar granulation ever. SuFI is a diffraction limited filter imager with an effective focal length of 121m, working in 5 distinct wavelength

We present the current status of the QUIJOTE (Q-U-I JOint TEnerife) CMB Experiment, a new instrument which will start operations early in 2009 at Teide Observatory with the aim of characterizing the polarization of the CMB and other processes of galactic and extragalactic emission in the frequency range 10-30GHz and at large angular scales.

We present results on the disk-disk major merger fraction evolution up to z˜1 in SPITZER/IRAC selected samples in the GOODS-S field. We pick as merger remnants sources with high asymmetry (A). We take into account the experimental errors in photometric redshift and index A, that tend to overestimate the merger fraction, by maximum likelihood
