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…
