In this paper we analyse the structure of a small sample of galaxies using a set of CCD images in standard photometric bands presented in a previous paper (del Rio & Cepa 1998a, hereafter cite{p2}). The galaxies are NGC 157, 753, 895, 4321, 6764, 6814, 6951, 7479 and 7723, and the selected bands were B and I. Seven galaxies are grand design, i.e

Published conference proceedings have been called both a great advancement and a despicable curse for astronomy. In reality, they simply fill a niche that any scientific society must have filled to remain healthy. Two obvious items they address are 1) the need for timely dissemination of research and 2) the need to provide a "snapshot" of the

The relationship between the emission of coronal lines (CLs) and nuclear activity in 36 Type 1 and 18 Type 2 active galactic nuclei (AGNs) is analyzed, for the first time, based on near-infrared (0.8-2.4 μm) spectra. The eight CLs studied, of Si, S, Fe, Al, and Ca elements and corresponding to ionization potentials (IPs) in the range 125-450 eV

The Near-Infrared S0 Survey (NIRS0S; Laurikainen, Salo, and Buta 2005, MNRAS, 362, 1319) is an attempt to obtain a statistically well-defined database of images of S0s from which the properties of S0 bars may be fairly compared to those of spirals. The main goal of the survey is to provide information on the the distribution of bar strengths in S0

Alcatel Space together with Laboratoire d'Astrophysique de Marseille is leading one of two competing consortia of European industry and scientific institutions tasked by ESA with carrying out detailed assessment and definition studies of the Near-Infrared Spectrometer for NGST. In this paper, we present the current baseline instrument concept that

The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS project includes 535,995 new galaxy spectra (median z ~ 0.52), 102,100 new quasar spectra (median z ~ 2.32), and 90,897 new stellar spectra, along with the data
