A large fraction of all stars, after experiencing heavy winds at the end of the Asymptotic Giant Branch (AGB) phase, leave behind a core that is below the...
Winds of metal-poor OB stars: Updates from HST-COS UV spectroscopy
In the race to break the SMC frontier and reach metallicity conditions closer to the First Stars the information from UV spectroscopy is usually overlooked. New...
Winds of Very Low Metallicity OB Stars: Beyond the Magellanic Clouds
Very low metallicity massive stars are a key piece to understanding the infant, extremely metal-poor Universe and its early development. Our models for these...
WINERED as a Stepping Stone for the Cosmic Distance Scale
We present the Oscillating Stars with wIneRed near-Infrared Spectroscopy (OSIRIS) project, aimed at deriving accurate chemical abundances of primary distance...
WINGS: Structural Parameters of Galaxies in Nearby Clusters
We present the first results of an ambitious work still in progress. We are modeling the light distribution of a large sample (˜10000) of cluster galaxies from...
NASA's Wide-field Survey Explorer (WISE) mapped the sky in four bands at 3.4, 4.6, 12, and 22 μm during its mission. Published on 14 April 2011, the WISE...
Witnessing the rapid growth of disk galaxies over cosmic time
The Hubble and James Webb Space Telescopes, with their outstanding depth and spatial resolution, are opening up the possibility of studying the edges of disk...
Observations of the WMAP sources were made using the AMI-SA during 14 separate observing runs between 2007 April and 2008 September. Observations of the WMAP...
WMAP 3-yr sources at 16 and 33GHz. II. (Franzen+, 2009)
Using the Arcminute Microkelvin Imager (AMI) at 16GHz and the Very Small Array (VSA) at 33GHz to make follow-up observations of sources in the New Extragalactic...
