We present coincident observations of the cosmic microwave background (CMB) from the Very Small Array (VSA) and Cosmic Background Imager (CBI) telescopes. The consistency of the full data sets is tested in the map plane and the Fourier plane, prior to the usual compression of CMB data into flat bandpowers. Of the three mosaics observed by each

The SAURON integral-field spectrograph was used to observe the central area of the barred spiral galaxy M100 (NGC 4321). M100 contains a nuclear ring of star formation, fueled by gas channeled inward by the galaxy's bar. We present maps of emission-line strengths, absorption-line strength indices, and the gas velocity dispersion across the field

This Letter presents an analysis of three-dimensional vector currents and temperatures observed in a sunspot from the photosphere to the chromosphere, spanning a range of heights of approximately 1500 km. With this unique data set, based on novel spectropolarimetric observations of the 850 nm spectral region, it is possible to conduct for the first

We present 16600 equivalent widths (EWs) in the spectra of 100 and 94 stars with and without known planets, respectively. We have measured line-by-line EWs of about 80 spectral lines for the refractory elements Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni. The EWs of about 14 lines of Na, Mg and Al in 53 new comparison spectra have been added to the previous
