As astrophysicists, we are used to extracting physical information from the observations. The usual procedure is to propose a parametric physical model to...
CALIFA is the largest IFS survey ever performed up to date. Recently started, it will observe ~600 galaxies in the Local Universe with PPAK at the 3.5m of the...
Can solar activity and cosmic rays save us from global warming?
Global warming has often been portrayed as being connected only to greenhouse gasses in widespread media. However, these are just one of many factors...
I revisit the claim of Dark Energy detection after stacking CMB data on the angular position of voids and superclusters in Sloan Data. I examine the...
We present recent theoretical and empirical results concerning the accuracy of Cepheid distance estimates based on optical and near-infrared (NIR) Period...
Characterization of stars (with and without planets) from Hubble absolute flux spectrophotometry
This talk shows an spectrophotometric analysis of HD 209458 and 18 A type stars. We have used absolute flux spectrophotometry obtained with the Hubble Space...
Characterizing the circum/inter-galactic medium in emission around z~2-3 quasars
The exquisite sensitivity of MUSE on VLT/ESO together with the recent discovery of Enormous (>200 kpc) Lyman-Alpha Nebulae (ELAN) around radio-quiet z~2-3...
Chemical Cartography in the Milky Way with SDSS/APOGEE
The SDSS Apache Point Observatory Galactic Evolution Experiment (APOGEE) has collected high resolution near-IR spectra of several hundred thousand stars across...
Chemical composition of cosmic dust in the solar vicinity
Cosmic dust is an elusive component of the interstellar medium (ISM) because it is difficult to be observed. Despite the dust is a key ingredient in the...
