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...
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...
Searching for Missing Baryons with WMAP and PLANCK
About half the baryons in the local Universe could be in the form of a Warm Hot Intergalactic Medium (WHIM). If a large fraction of the gas is ionized, it could...
Shedding light on the darkest galaxies: the Local Group dwarfs
Crucial issues in cosmology and astrophysics are to understand the process of galaxy formation and evolution and the nature of what appears to be the dominant...
The first galaxies are thought to have started the reionization of the Universe, that is the transformation of the cosmic hydrogen from its initial neutral to...
Numerical simulations have played a crucial role in the development of modern cosmology and in the establishment of LCDM. In this talk, I will review the main...
Small bodies and big impacts: comets, asteroids, and the origin of water and organics on Earth
The role of asteroids and comet impacts on the origin of Earth’s water and organic molecules is reviewed. Earth is believed to have formed dry, and magma oceans...
