We present the result of a search for Cepheids in the Local Group dwarf irregular galaxy Pegasus. We identified 20 Cepheid stars with periods 0.6d P 15.3d, compared them with previously published Cepheids, and carried out an accurate completeness analysis in order to obtain the fraction lost. Using their period-luminosity relation, we obtain a

ALHAMBRA is a survey of eight separate regions of the sky with a total area of 4 sq. deg. The fields are observed with the LAICA (visible) and OMEGA-2000 (near infrared) cameras mounted on the 3.5 m telescope of CAHA observatory. The survey is done with a set of 20 adjacent medium-band filters that cover the visible range. These filters, together

The ACS Survey of Globular Clusters has used Hubble Space Telescope's Wide-Field Channel to obtain uniform imaging of 65 of the nearest globular clusters to provide an extensive homogeneous data set for a broad range of scientific investigations. The survey goals required not only a uniform observing strategy, but also a uniform reduction strategy

The details of the early star formation history of isolated dwarf galaxies can shed light on the role of the cosmic re-ionization and supernova feedback in galaxy formation and evolution. In this paper, we present the project { Local Cosmology from Isolated Dwarfs (LCID), aimed at deriving detailed star formation histories for a sample of Local

We explore the size evolution of 831 very massive galaxies (Mstar≥1011 h70-2 Msun) since z˜ 2 using the combined capabilities of the large near infrared Palomar/DEEP-2 survey, and the superb resolution of the HST ACS camera. We split our sample according to their light concentration using the Sérsic index n. At a given stellar mass, both low (n 2.5
