Recently, huge photometric databases are being obtained for the Magellanic Clouds and other Local Group galaxies. These data allow, not only to study in great detail the star formation history of these systems, but also provide important information on details of stellar evolution theory. In the case of the LMC, two structures not previously

We present the results of a comparison between the environments of (1) a complete sample of 46 southern 2-Jy radio galaxies at intermediate redshifts (0.05 z 0.7), (2) a complete sample of 20 radio-quiet type-2 quasars (0.3 ≤ z ≤ 0.41), and (3) a control sample of 107 quiescent early-type galaxies at 0.2 ≤ z 0.7 in the Extended Groth Strip. The

We present deep photometry of the Carina dwarf spheroidal galaxy in the B and V filters from CTIO/MOSAIC out to and beyond the tidal radius of rell ≈ 0.48 degrees. The accurately calibrated photometry is combined with spectroscopic metallicity distributions of red giant branch (RGB) stars to determine the detailed star formation and chemical

The study of the Extremly Red Objects (EROs), is the importance for setting constraints on the first epoch of massive galaxy formation, for exploring the population of dust reddened starburst and for testing models of galaxy formation in general. They are defined as objects with I-K>4(Vega). The traditional picture identifies the EROs either with

We present the 90-μm luminosity function of the Final Analysis of the European Large Area ISO Survey (ELAIS), extending the sample size of our previous analysis (Paper IV) by about a factor of 4. Our sample extends to z= 1.1, ~50 times the comoving volume of Paper IV, and 107.7 h-2L/Lsolar 1012.5. From our optical spectroscopy campaigns of the

In this presentation I will describe the current status of the European Solar Telescope (EST) project. The EST design has a 4-m aperture to achieve both a large photon collection and very high spatial resolution. It includes a multi-conjugate adaptive system integrated in the light path for diffraction-limited imaging. The optical train is
