The Local Universe, i.e. the ensemble of structures located a few Mpc away from our Galaxy, is the part of the Universe that can be best observed and thus is...
Rotational velocities in Galactic OB stars: the Fourier transform revolution
The application of the Fourier transform (FT) technique to high resolution spectra of OB-type stars has challenged our previous knowledge about stellar rotation...
S4G: The Spitzer Survey of Stellar Structure in Galaxies
Galaxies are the basic building blocks of the Universe, and understanding their formation and evolution is crucial to many areas of current astrophysical...
Scriptures, science and mythology: astronomy in Indian cultures
Human beings are born astronomers. Ever since they learned to walk upright they have looked at the sky and wondered. The sky has remained the same but not its...
SDSS at the IAC. Ongoing SDSS-III science and SDSS-IV planning: APOGEE-2, eBOSS, MaNGA, TDSS and SPIDERS
The IAC is the only Spanish Institution participating as a full member in SDSS-III (2009-2014). The survey finishes in June 2014, and will publicly release all...
SDSS-III: Developments and Participation at the IAC

SDSS-III: news, data access, and activities at the IAC
Since June last year, the IAC is an institutional member in the third phase of the Sloan Digital Sky Survey (SDSS-III). Many of us have already got an account...
SDSS-III and its four surveys, BOSS, SEGUE-2, MARVELS and APOGEE, came to an end in June 2014, and all data were publicly released last January. The IAC...
Search for weak periodic signals buried in noisy time series using modern Bayesian methods: secondary eclipses in Kepler light curves
Detection and characterisation of weak periodic signals from noisy time series is a common problem in many different fields of astrophysics. Here I detail one...
