TLDR
The second public data release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey as discussed by the authors contains over 1.5 million spectra.Abstract:
This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the 100 galaxies of the First Public Data Release (DR1). Data were obtained with the integral-field spectrograph PMAS /PPak mounted on the 3.5 m telescope at the Calar Alto observatory. Two different spectral setups are available for each galaxy, (i) a low-resolution V500 setup covering the wavelength range 3745-7500 A with a spectral resolution of 6.0 A (FWHM); and (ii) a medium-resolution V1200 setup covering the wavelength range 3650-4840 A with a spectral resolution of 2.3 A (FWHM). The sample covers a redshift range between 0.005 and 0.03, with a wide range of properties in the color-magnitude diagram, stellar mass, ionization conditions, and morphological types. All the cubes in the data release were reduced with the latest pipeline, which includes improved spectrophotometric calibration, spatial registration, and spatial resolution. The spectrophotometric calibration is better than 6% and the median spatial resolution is 2´´ 4. In total, the second data release contains over 1.5 million spectra.read more

Large-scale outflows in luminous QSOs revisited: The impact of beam smearing on AGN feedback efficiencies
TL;DR: In this article, the impact of beam smearing on the kinematics and energy of a bright unresolved NLR due to seeing has been investigated, and it was shown that the energy of the unresolved NLRs can be reduced by two magnitudes for a conical outflow and one magnitude for an unresolved outflow after PSF deblending.

TL;DR: In this article, the stellar properties of 44 face-on spiral galaxies from the Calar Alto Legacy Integral Field Area survey via full spectrum fitting techniques were studied. And the authors observed an upturn in the age profiles for 17 out of these 44 galaxies with reliable stellar information up to their outer parts.

The relationship between infrared, optical, and ultraviolet extinction
TL;DR: In this article, the average extinction law over the 3.5 micron to 0.125 wavelength range was derived for both diffuse and dense regions of the interstellar medium. And the validity of the law over a large wavelength interval suggests that the processes which modify the sizes and compositions of grains are stochastic in nature.
