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

We present a preliminary analysis of penumbral spectra observed with unprecedented angular resolution (0.2 arcsec) using the new Swedish 1-m Solar Telescope. The use of a non-magnetic line allows us to measure Doppler shifts without magnetic contamination. The observed Doppler shifts depend on the part of the line used for measuring, indicating

We report on the analysis of hard-state power spectral density function (PSD) of GX 339-4 down to the soft X-ray band, where the disc significantly contributes to the total emission. At any luminosity probed, the disc in the hard state is intrinsically more variable than in the soft state. However, the fast decrease of disc variability as a
