We present direct evidence for anomalous microwave emission in the Perseus molecular cloud, which shows a clear rising spectrum from 11 to 17 GHz in the data from the COSMOSOMAS experiment. By extending the frequency coverage using W ilkinson Microwave Anisotropy Probe maps convolved with the COSMOSOMAS scanning pattern, we reveal a peak flux

As part of ELAIS, ISOCAM observations were carried out covering 10.3deg2 at 15um. The observations were carried out in raster mode, with most of the survey area confined to three northern fields (N1, 2.67deg2; N2, 2.67deg2; N3, 0.88deg2) (2 data files).

We carried out CCD observations on 39 nights from September, 1999 to February, 2003. Standard Johnson R filtered and unfiltered data were obtained, using the 60/90/180cm Schmidt-telescope of the Konkoly Observatory. (3 data files).

High-resolution UCLES/AAT spectra are presented for nine B-type supergiants in the SMC, chosen on the basis that they may show varying amounts of nuclear-synthetically processed material mixed to their surface. These spectra have been analysed using a new grid of approximately 12 000 non-LTE line blanketed tlusty model atmospheres to estimate

Este trabajo está orientado a calcular las masas estelares de una muestra de galaxias luminosas compactas azules (LBCGs) a partir de la fotometría en filtros ópticos y del infrarrojo cercano. Se han medido también las masas estelares para muestras de galaxias espirales y elípticas a modo de comparación. Para la determinación de las masas estelares

We present results from 30 nights of observations of the open cluster NGC 7789 with the Wide Field Camera on the Isaac Newton Telescope, La Palma. From ~900 epochs, we obtained light curves and Sloan r'-i' colours for ~33000 stars, with ~2400 stars having better than 1 per cent precision. We expected to detect ~2 transiting hot Jupiter planets if 1
