Stacking the Cosmic Web in Fluorescent Lyman alpha Emission with MUSE
Sofia G. Gallego, Sebastiano Cantalupo, Simon Lilly +12
Cosmological simulations suggest that most of the matter in the Universe is distributed along filaments connecting galaxies. Illuminated by the cosmic UV background (UVB), these st…
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 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…
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 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…
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…
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…
Integral field spectroscopy of a sample of nearby galaxies: II. Properties of the H ii regions
S. F. Sanchez, F. F. Rosales-Ortega, R. A. Marino +17
In this work we analyze the spectroscopic properties of a large number of H ii regions, \sim2600, located in 38 galaxies. The sample of galaxies has been assembled from the face-on…
The ionized gas in the CALIFA early-type galaxies I. Mapping two representative cases: NGC 6762 and NGC 5966
C. Kehrig, A. Monreal-Ibero, P. Papaderos +18
As part of the CALIFA survey, we conducted a thorough 2D analysis of the ionized gas in two E/S0 galaxies, NGC6762 and NGC5966, aiming to shed light on the nature of their warm ion…
Spatially resolved properties of the grand-design spiral galaxy UGC 9837: a case for high-redshift 2D observations
K. Viironen, S. F. Sanchez, E. Marmol-Queralto +8
Context. We carry out a detailed 2D study of the ionised gas in the local universe galaxy UGC9837. In nearby galaxies, like the galaxy in question here, the spatial distribution of…

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…
Integral Field Spectroscopy of a sample of nearby galaxies. I. Sample, Observations and Data Reduction
E. Marmol-Queralto, S. F. Sanchez, R. A. Marino +6
Aims: Integral Field Spectroscopy (IFS) is a powerful approach for the study of nearby galaxies since it enables a detailed analysis of their resolved physical properties. Here we…
CALIFA, the Calar Alto Legacy Integral Field Area survey: Early Report
S. F. Sánchez, R. C. Kennicutt, A. Gil de Paz +8
We present the Calar Alto Legacy Integral Field Area survey (CALIFA). CALIFA's main aim is to obtain spatially resolved spectroscopic information for ~600 galaxies of all Hubble ty…
