A detailed study of the spiral galaxy UGC9837 is carried out based on the IFU spectroscopic data from the pilot survey of the Calar Alto Legacy Field Survey (CALIFA). The integrated, radial and spatially resolved properties of the ionized gas are studied. In addition the possible biases caused by using a fixed aperture in studying galaxy properties

We present here the Calar Alto Legacy Integral Field spectroscopy Area survey (CALIFA). CALIFA is large collaboration comprising more than 50 astronomers of 8 different countries, which main aim is to obtain detailed spatially resolved spectroscopic information of ˜ 600 galaxies of any type at the Local Universe (0.005

Context: Free-floating substellar candidates with estimated theoretical masses of as low as ∼5 Jupiter masses have been found in the ∼3 Myr old σ Orionis open cluster. As the overlap with the planetary mass domain increases, the question of how these objects form becomes important. The determination of their number density and whether a mass cut

The San Fernando automatic meridian circle (CMASF) is a meridian telescope built by Grubb-Parsons in 1948 fully automated between 1987 and 1995. In 1996 was moved from the Real Instituto y Observatorio de la Armada (ROA) in San Fernando to the Carlos U. Cesco (CUC) mountain observatory in San Juan (Argentine). The CUC is owned by the Observatorio

CCD UBV photometry of 2279 stars in Sextans A is presented. Differences with the photometric scales of Sandage and Carlson (1985) and Hoessel et al. (1983) are discussed; recalibration of the Sandage and Carlson data for Cepheids in Sextans A results in a smaller value for the distance modulus, μ = 25.6. A similar value for the distance modulus is

R-band photometric and isophotal parameters for 171 late-type dwarf galaxies. For each galaxy the date of observation, seeing, adopted distance, equatorial coordinates, apparent magnitudes, central surface brightnesses, isophotal diameters and fractional light radii are given. For 46 galaxies, photometric and isophotal parameters derived from B
