CALIFA, the Calar Alto Legacy Integral Field Area survey. II. First public data release
CALIFA collaboration, B. Husemann, K. Jahnke +74
We present the first public data release of the CALIFA survey. It consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005<z<0.03) galaxies, ob…
Galaxy And Mass Assembly (GAMA): The mass-metallicity relationship
C. Foster, A. M. Hopkins, M. Gunawardhana +37
Context: The mass-metallicity relationship (MMR) of star-forming galaxies is well-established, however there is still some disagreement with respect to its exact shape and its poss…
Integral field spectroscopy of a sample of nearby galaxies: II. Properties of the H ii regions
S. F. Sanchez, F. F. Rosales-Ortega, R. A. Marino +17
In this work we analyze the spectroscopic properties of a large number of H ii regions, \sim2600, located in 38 galaxies. The sample of galaxies has been assembled from the face-on…
On the 3D structure of the mass, metallicity, and SFR space for SF galaxies
Maritza A. Lara-Lopez, Angel R. Lopez-Sanchez, Andrew M. Hopkins
We demonstrate that the space formed by the star-formation rate (SFR), gas-phase metallicity (Z), and stellar mass (M), can be reduced to a plane, as first proposed by Lara-Lopez e…
Eliminating Error in the Chemical Abundance Scale for Extragalactic HII Regions
Angel R. Lopez-Sanchez, M. A. Dopita, L. J. Kewley +3
In an attempt to remove the systematic errors which have plagued the calibration of the HII region abundance sequence, we have theoretically modeled the extragalactic HII region se…
The ionized gas in the CALIFA early-type galaxies I. Mapping two representative cases: NGC 6762 and NGC 5966
C. Kehrig, A. Monreal-Ibero, P. Papaderos +18
As part of the CALIFA survey, we conducted a thorough 2D analysis of the ionized gas in two E/S0 galaxies, NGC6762 and NGC5966, aiming to shed light on the nature of their warm ion…
