Neutrinos in Astro- and Particle Physics

Neutrinos in Astro- and Particle Physics

The community vigorously moves towards new experimental infrastructures to resolve outstanding key questions in neutrino astro- and particle physics, notably the neutrino mass hierarchy, the octant of Θ23, leptonic CP-violation, neutrino-less double beta decay and sterile neutrinos. Large new underground detectors and neutrino-telescope extensions would not only allow to study those intrinsic neutrino particle properties,…

Star formation in galaxies: from small to large scales

Star formation in galaxies: from small to large scales

Star formation is a vibrant field in contemporary astrophysics, combining a rich diversity of physics and chemistry, sophisticated simulations with supercomputers, and cutting edge observational facilities on the ground and in space to tackle both fundamental and complex problems related to the origin of stars and galaxies in our relative neighbourhood - the Milky Way…

Digging deep into the extragalactic infrared sky

Digging deep into the extragalactic infrared sky

Over the last years, IR Extragalactic Astronomy has made rapid progress thanks to major survey efforts carried out with ground-based and space observatories. These studies are preparing the ground for the science to be tackled with the next generation of IR telescopes, in particular the James Webb Space Telescope (JWST).  (altro…)

EWASS 2014: European Week of Astronomy and Space Science

EWASS 2014: European Week of Astronomy and Space Science

The European Week of Astronomy and Space Science (EWASS, formerly JENAM) is the annual meeting of the European Astronomical Society (EAS). With more than 20 years of tradition, it has imposed itself as the largest conference for European astronomy. In addition to plenary sessions and the award of prestigious prizes, the conference hosts many symposia held…

Fast outflows in massive stars

Fast outflows in massive stars

Massive Stars are among the dominant sources of light in galaxies. Their high surface temperature, maintained over several evolutionary phases, implies that most of this light is emitted as ultraviolet photons. Through line scattering and the corresponding momentum transfer, this intense radiation field is able to accelerate fast outflows.  (altro…)

Gliese 832c, una super-Terra vicina potenzialmente abitabile

Un gruppo internazionale di astronomi guidati da Robert A. Wittenmyer della University of New South Wales (UNSW) in Sydney, Australia riportano la scoperta di una nuova super-Terra potenzialmente abitabile nel sistema stellare Gliese 832, una nana rossa nella costellazione della Gru che si trova relativamente vicina, 16 anni-luce. La stella è già nota perchè ospita un oggetto gioviano…
