A characteristic oxygen abundance gradient in galaxy disks unveiled with CALIFA
S. F. Sanchez, F. F. Rosales-Ortega, J. Iglesias-Paramo +35
We present the largest and most homogeneous catalog of HII regions and associations compiled so far. The catalog comprises more than 7000 ionized regions, extracted from 306 galaxi…
The star formation history of CALIFA galaxies: Radial structures
R. M. González Delgado, E. Pérez, R. Cid Fernandes +24
We study the radial structure of the stellar mass surface density () and stellar population age as a function of the total stellar mass and morphology for a sample of 107 galaxi…
Aperture corrections for disk galaxy properties derived from the CALIFA survey. Balmer emission lines in spiral galaxies
J. Iglesias-Páramo, J. M. Vílchez, L. Galbany +37
This work investigates the effect of the aperture size on derived galaxy properties for which we have spatially-resolved optical spectra. We focus on some indicators of star format…
The complex nature of the nuclear star cluster in FCC 277
Mariya Lyubenova, Remco C. E. van den Bosch, Patrick Cote +6
Recent observations have shown that compact nuclear star clusters (NSCs) are present in up to 80% of galaxies. However, detailed studies of their dynamical and chemical properties…
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…
Integrated J- and H-band spectra of globular clusters in the LMC: implications for stellar population models and galaxy age dating
Mariya Lyubenova, Harald Kuntschner, Marina Rejkuba +3
(Abridged) The rest-frame near-IR spectra of intermediate age (1-2 Gyr) stellar populations are dominated by carbon based absorption features offering a wealth of information. Yet,…
CALIFA, the Calar Alto Legacy Integral Field Area survey: I. Survey presentation
S. F. Sanchez, R. C. Kennicutt, A. Gil de Paz +69
We present here the Calar Alto Legacy Integral Field Area (CALIFA) survey, which has been designed to provide a first step in this direction.We summarize the survey goals and desig…
Integrated K-band spectra of old and intermediate-age globular clusters in the Large Magellanic Cloud
Mariya Lyubenova, Harald Kuntschner, Marina Rejkuba +4
Current stellar population models have arguably the largest uncertainties in the near-IR wavelength range, partly due to a lack of large and well calibrated empirical spectral libr…
