Photo-z optimization for measurements of the BAO radial direction
Daniel Roig, Licia Verde, Jordi Miralda-Escude +2
Baryon Acoustic Oscillations (BAO) in the radial direction offer a method to directly measure the Universe expansion history, and to set limits to space curvature when combined to…
The Role of Massive Agb Stars in the Early Solar System Composition
Josep M. Trigo-Rodriguez, Domingo Anibal Garcia-Hernandez, Maria Lugaro +4
We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system. Recent identificatio…
Delayed Recombination and Standard Rulers
Francesco De Bernardis, Rachel Bean, Silvia Galli +3
Measurements of Baryonic Acoustic Oscillations in galaxy surveys have been recognized as a powerful tool for constraining dark energy. However, this method relies on the knowledge…
Evolution of Magnetic Fields in High Mass Star Formation: SMA dust polarization image of the UCHII region G5.89-0.39
Ya-Wen Tang, Paul T. P. Ho, Josep Miquel Girart +3
We report high angular resolution (3") Submillimeter Array (SMA) observations of the molecular cloud associated with the Ultra-Compact HII region G5.89-0.39. Imaged dust continuum…
Axions and the white dwarf luminosity function
J. Isern, S. Catalan, E. Garcia-Berro +1
The evolution of white dwarfs can be described as a simple cooling process. Recently, it has been possible to determine with an unprecedented precision their luminosity function, t…
MAGIC Observations of PG 1553+113 during a Multiwavelength Campaign in July 2006
MAGIC Collaboration, Albert
The active galactic nucleus PG 1553+113 was observed by the MAGIC telescope in July 2006 during a multiwavelength campaign, in which telescopes in the optical, X-ray, and very high…
