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 survey goals and design, including sample selection observational strategy.We also showcase data taken during observing runs (June/July 2010) outline reduction pipeline, quality control schemes general characteristics of reduced data. This is obtaining spatially resolved spectroscopic information diameter selected $\sim600$ galaxies Local...
We present the largest and most homogeneous catalog of HII regions associations compiled so far. The comprises more than 7000 ionized regions, extracted from 306 galaxies observed by CALIFA survey. describe procedures used to detect, select, analyse spectroscopic properties these regions.

Aims. We investigate the fueling and feedback of star formation nuclear activity in NGC 1068, a nearby (D = 14 Mpc) Seyfert 2 barred galaxy, by analyzing distribution kinematics molecular gas disk. aim to understand if how accretion can self-regulate.
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 central mass-accreting supermassive black hole (AGN) of low luminosity, making LINER galaxies the largest AGN-sub-population, dominating in numbers over higher luminosity Seyfert and quasars. This, however, poses serious problem. While inferred energy balance is plausible, many LINERs clearly do not any other independent...
This paper characterizes the radial structure of stellar population properties galaxies in nearby universe, based on 300 from CALIFA survey. The sample covers a wide range Hubble types, and galaxy mass. We apply spectral synthesis techniques to recover mass surface density, extinction, light mass-weighted ages, metallicity, for each spatial resolution element our target galaxies. To study mean trends with overall properties, individual profiles are stacked seven bins morphology. confirm that...
We present the first public data release of CALIFA survey. It consists science-grade optical datacubes for 100 eventually 600 nearby (0.005<z<0.03) galaxies, obtained with integral-field spectrograph PMAS/PPak mounted on 3.5m telescope at Calar Alto observatory. The galaxies in DR1 already cover a wide range properties color-magnitude space, morphological type, stellar mass, and gas ionization conditions. This offers potential to tackle variety open questions galaxy evolution using spatially...

We have discovered small whirlpools in the Sun, with a size similar to terrestrial hurricanes (≲0.5 Mm). The theory of solar convection predicts them, but they had remained elusive so far. vortex flows are created at downdrafts where plasma returns interior after cooling down, and we detect them because some magnetic bright points (BPs) follow logarithmic spiral on their way being engulfed by downdraft. Our disk-center observations show 0.9 × 10−2 vortexes per Mm2, lifetime order 5 minutes,...

We report ALMA observations of CO(3-2) emission in the Seyfert 2 double-barred galaxy NGC1433, at unprecedented spatial resolution 0.5"=24 pc. Our aim is to probe AGN feeding and feedback phenomena through morphology dynamics gas inside central kpc. The CO map, which covers whole nuclear region (nuclear bar ring), reveals a gaseous spiral structure, ring encircling stellar bar. This well correlated with dusty seen Hubble Space Telescope images. winds up pseudo-ring 200 pc radius, might...
