DES rivela una supernova 'super luminosa'

Le prime immagini realizzate dalla survey denominata Dark Energy Survey (DES) hanno permesso di rivelare un oggetto esotico, ossia una supernova 'superluminosa' esplosa in una galassia 7,8 miliardi di anni fa. Denominata con la sigla DES13S2cmm, la sua luminosità supera quella di intere galassie e con ogni probabilità potrà essere osservata ancora tra 6 mesi circa, cioè alla fine…

Testable solutions to the dark matter problem: theory and observations

Testable solutions to the dark matter problem: theory and observations

These symposia will summarize the state-of-the-art in our understanding of the nature of dark matter (DM) and discuss the most promising avenues of research in this field. Our goal is to bring together experts in (i) observations relevant to the study of the DM phenomenology on a large range of galactic scales, (ii) numerical simulations…

The outer regions of extrasolar planetary systems

The outer regions of extrasolar planetary systems

Over the past two decades we learned that extrasolar planets are common in the Galaxy and that they exhibit an astonishing diversity in all accessible parameters. Planets that orbit close to their host star, i.e. at orbital distances of less than 1 AU, are easier to access observationally, thus represent the bulk of the exoplanet…

2014 Higgs Symposium: New Horizons in Particle Cosmology

2014 Higgs Symposium: New Horizons in Particle Cosmology

The Standard Model of Cosmology is now on a solid observational foundation. But the empirical success of the model forces us to consider its outstanding fundamental problems: What drives the current expansion of the Universe to accelerate? Did a period of Cosmological Inflation set the initial conditions for the observable Universe? What is the nature…

What powers Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters?

What powers Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters?

Anomalous X-ray Pulsars (AXPs) and Soft Gamma-ray Repeaters (SGRs) are young, isolated neutron stars, which emit bright bursts of hard X-rays and, more rarely, exceptionally energetic giant flares. They are believed to have strong external magnetic fields of the order of 1014 - 1015G, reaching even higher values in their interior, and are known as magnetars.…
