Parsec-scale dust distributions in Seyfert galaxies - Results of the MIDI AGN snapshot survey

Konrad R. W. Tristram, David Raban, Klaus Meisenheimer +11

The emission of warm dust dominates the mid-infrared spectra of active galactic nuclei (AGN). Only interferometric observations provide the necessary angular resolution to resolve…

New distance and depth estimates from observations of eclipsing binaries in the SMC

Pierre L. North, Romain Gauderon, Frederic Royer

A sample of 33 eclipsing binaries observed in a field of the SMC with FLAMES@VLT is presented. The radial velocity curves obtained, together with existing OGLE light curves, allowe…

Enlightening the structure and dynamics of Abell 1942

H. V. Capelato, D. Proust, G. B. LIma Neto +2

We present a dynamical analysis of the galaxy cluster Abell 1942 based on a set of 128 velocities obtained at the European Southern Observatory. Data on individual galaxies are pre…

Checking the reliability of equivalent width R23 for estimating metallicities of galaxies

Y. C. Liang, F. Hammer, S. Y. Yin

We verify whether the O/H abundances of galaxies can be derived from the equivalent width (EW) R23 instead of the extinction-corrected flux R23, and eventually propose a method of…

The direct oxygen abundances of metal-rich galaxies derived from electron temperature

Y. C. Liang, F. Hammer, S. Y. Yin +3

We aim to derive the electron temperature Te in the gas of metal-rich star-forming galaxies, which can be obtained from their ratios of auroral lines [O II]7320,7330 to nebular lin…

Empirical strong-line oxygen abundance calibrations from galaxies with electron temperature measurements

S. Y. Yin, Y. C. Liang, F. Hammer +4

We determine the gas-phase oxygen abundance for a sample of 695 galaxies and H II regions with reliable detections of [O III]4363, using the temperature-sensitive Te method. Our ai…
