The effects of spatial resolution on Integral Field Spectrograph surveys at different redshifts. The CALIFA perspective
D. Mast, F. F. Rosales-Ortega, S. F. Sanchez +27
Over the past decade, 3D optical spectroscopy has become the preferred tool for understanding the properties of galaxies and is now increasingly used to carry out galaxy surveys. L…
Are Wolf-Rayet stars able to pollute the interstellar medium of galaxies? Results from the integral field spectroscopy
Enrique Perez-Montero, Carolina Kehrig, Jarle Brinchmann +3
We investigate the spatial distribution of chemical abundances in a sample of low metallicity Wolf-Rayet (WR) galaxies selected from the SDSS. We used the integral field spectrosco…
The O3N2 and N2 abundance indicators revisited: improved calibrations based on CALIFA and Te-based literature data
R. A. Marino, F. F. Rosales-Ortega, S. F. Sánchez +31
The use of IFS is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies both locally and at high redshift. The main g…
Nebular emission and the Lyman continuum photon escape fraction in CALIFA early-type galaxies
P. Papaderos, J. M. Gomes, J. M. Vilchez +21
We use deep integral field spectroscopy data from the CALIFA survey to study the warm interstellar medium (WIM) of 32 nearby early-type galaxies (ETGs). We propose a tentative subd…
Uncovering multiple Wolf-Rayet star-clusters and the ionized ISM in Mrk178: the closest metal-poor Wolf-Rayet HII galaxy
C. Kehrig, E. Perez-Montero, J. M. Vilchez +9
New integral field spectroscopy (IFS) has been obtained for the nearby metal-poor WR galaxy Mrk178 to examine the spatial correlation between its WR stars and the neighbouring ioni…
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…
The metallicity - redshift relations for emission-line SDSS galaxies: examination of the dependence on the star formation rate
L. S. Pilyugin, M. A. Lara-Lopez, E. K. Grebel +5
We analyse the oxygen abundance and specific star formation rates (sSFR) variations with redshift in star-forming SDSS galaxies of different masses. We find that the maximum value…
