Abstract:
The European Extremely Large Telescope is in its detailed design phase until the end of 2010. During this period, the telescope design is being consolidated and instrument and operation concepts are being studied. The scientific users are feeding back requirements into the project in numerous ways. One of them, the Design Reference Science Plan, was an opportunity for the entire community to provide direct feedback to the project. Here, we summarise the first results from this study. The full report will appear in the first half of 2010.

Abstract:
The low resolution spectropolarimetric observations obtained with FORS1 at the VLT have often been used for investigating magnetic fields in hot stars. Here we describe the first investigation of the magnetic field over the stellar rotation in a cool late-type star, FK Com, based on FORS1 spectropolarimetry. We measure the mean longitudinal magnetic field from nine circularly polarised spectra, and study its behaviour over the stellar rotation. The magnetic field measurements are compared to a simultaneous stellar surface temperature map obtained with Doppler imaging techniques. These observations reveal two cool spots on the surface, and indicate that the main cool region coincides with the maximum value of the mean longitudinal magnetic field. Additionally, only 0.25 in phase apart from the main spot, the secondary spot is located at a similar phase to the field minimum. The observations can be interpreted as two spots having different magnetic field polarities, implying that the starspot configuration on FK Com is similar to that observed in the Sun.

Abstract:
We present the latest results from the LABOCA Extended Chandra Deep Field South (ECDFS) Submillimetre Survey (LESS), a joint 300-hour ESO–MPG survey of the 30 × 30 arcminute ECDFS field using the LABOCA camera on the 12-metre APEX telescope. This survey provides an important new waveband for comparison to previous studies of galaxies and active galactic nuclei (AGN) in the ECDFS, and one which is particularly sensitive to obscured starburst galaxies out to very high redshifts (z < 8). We highlight the identification in the LESS map of the highest redshift submillimetre galaxy currently known, as well as high significance statistical detections of a variety of star-forming galaxies and AGN, their clustering and evolution with redshift within the ECDFS.

Abstract:
In the 1980s and 1990s, the developments in sensitivity, size, and effective image quality of semiconductor detectors progressed faster and with lower cost than any equivalent increase in the geometrical light-collecting power of optical/infrared telescopes could have achieved. Now, in the era of Extra Large Telescopes, where light-collecting power is again increasing and ever more sophisticated space-borne instruments are in preparation, the growing maturity of detectors still forms an important cornerstone of these large investments. The recent workshop brought together many of the world’s leading detector developers, producers and users, as well as astronomers, to exchange ideas, questions and solutions with the aim of enabling detector systems to optimally support the exciting astronomy projects of the future.
