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…
The nature of LINER galaxies: Ubiquitous hot old stars and rare accreting black holes
R. Singh, G. van de Ven, K. Jahnke +19
Galaxies, which often contain ionised gas, sometimes also exhibit a so-called low-ionisation nuclear emission line region (LINER). For 30 years this was attributed to a central mas…
BRITE-Constellation: Nanosatellites for Precision Photometry of Bright Stars
W. W. Weiss, A. F. J. Moffat, A. Schwarzenberg-Czerny +15
BRITE-Constellation (where BRITE stands for BRIght Target Explorer) is an international nanosatellite mission to monitor photometrically, in two colours, brightness and temperature…
Characterization of the MALT90 Survey and the Mopra Telescope at 90 GHz
Jonathan B. Foster, Jill M. Rathborne, Patricio Sanhueza +23
We characterize the Millimeter Astronomy Legacy Team 90 GHz (MALT90) Survey and the Mopra telescope at 90 GHz. We combine repeated position-switched observations of the source G300…
The Mass-Metallicity relation explored with CALIFA: I. Is there a dependence on the star formation rate?
S. F. Sanchez, F. F. Rosales-Ortega, B. Jungwiert +40
We present the results on the study of the global and local M-Z relation based on the first data available from the CALIFA survey (150 galaxies). This survey provides integral fiel…
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…
