Star Formation Rate estimators: [OII]3727 vs. Halpha for local star-forming galaxies
A. Aragon-Salamanca, A. Alonso-Herrero, J. Gallego +4
The [OII]3727 emission line is frequently used as an indicator of the star formation rate (SFR) despite its complex dependence on metallicity and excitation conditions. We have ana…
12CO mapping of the low-metallicity BCD galaxy Mrk86
A. Gil de Paz, S. A. Silich, B. F. Madore +3
We have mapped the 12CO J=1-0 and J=2-1 line emission in Mrk86, one of the most metal-deficient Blue Compact Dwarf galaxies so far detected in 12CO. The 12CO emission is distribute…
A new approach in data reduction: proper handling of random errors and image distortions
N. Cardiel, J. Gorgas, J. Gallego +5
Data reduction procedures are aimed to minimize the impact of data acquisition imperfections on the measurement of data properties with a scientific meaning for the astronomer. To…
Mapping the star formation history of Mrk86: II. Stellar populations and global interpretation
A. Gil de Paz, J. Zamorano, J. Gallego
In this paper, continuation of Gil de Paz et al. (Paper I), we derive the main properties of the stellar populations in the Blue Compact Dwarf galaxy Mrk86. Ages, stellar masses, m…
Spectroscopic properties, spatial and luminosity distributions of the UCm survey galaxies
J. Gallego, J. Zamorano, M. Rego +1
A spectroscopic analysis of the whole sample of H Emission-Line Galaxies (ELGs) contained in the lists 1 & 2 of the Universidad Complutense de Madrid (UCM) objective-prism surve…
