The ESO Very Large Telescope Interferometer (VLTI) is the first general-user interferometer that offers near- and mid-infrared long-baseline interferometric observations in service and visitor mode to the whole astronomical community. Over the last two years, the VLTI has moved into its regular science operation mode with the two science

The anomalous microwave emission detected in the Perseus molecular complex by Watson et al. has been observed at 11 GHz through dual orthogonal polarizations with the COSMOSOMAS experiment. Stokes U and Q maps were obtained at a resolution of ~0.9d for a 30°×30° region including the Perseus molecular complex. Faint polarized emission has been

The design of slitmasks for multi-object spectroscopy with OSIRIS at the GTC telescope is now possible with the OSIRIS Mask Designer tool, a Java plug-in to the well-known JSky application. Observers can use external reduced images to design new MOS masks for future observations with OSIRIS and, once the instrument is up and running, will be able

Aims.We imaged the Lynds 723 dark nebula (L723) with the aim of studying the morphology of the Herbig-Haro object HH 223 and other line-emission nebula detected in the region. Methods: .We obtained deep narrow-band images in the Hα and [SII] lines and in the continuum nearby Hα of a field of ˜ 5' of the L723 dark nebula centered on HH 223. Results

We present the analysis of the first 18 months of data obtained with the COSMOSOMAS (COSMOlogical Structures On Medium Angular Scales) experiment at the Teide Observatory (Tenerife). Three maps have been obtained at 12.7, 14.7 and 16.3GHz covering 9000deg2 each with a resolution of ~1° and with sensitivities 49, 59 and 115μKbeam-1, respectively
