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…
Building galaxies, stars, planets and the ingredients for life between the stars. A scientific proposal for a European Ultraviolet-Visible Observatory (EUVO)
Ana I. Gómez de Castro, Thierry Appourchaux, Martin Barstow +36
The growth of luminous structures and the building blocks of life in the Universe began as primordial gas was processed in stars and mixed at galactic scales. The mechanisms respon…
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…
