A new approach to exploring quantum gravity

I fisici Lawrence Krauss e Frank Wilczek, rispettivamente dell'Arizona State University e dell'Australian National University, hanno pubblicato un lavoro in cui essi propongono una nuovo approccio sulla possibilità di quantizzare la forza di gravità misurando la polarizzazione della radiazione cosmica di fondo. Secondo gli scienziati, questo metodo potrebbe portare ad una connessione tra la radiazione…

Astrophysical Turbulence: From Galaxies to Planets

Astrophysical Turbulence: From Galaxies to Planets

In astrophysics and cosmology, fluid flow occurs on a large range of scales and under very different conditions, from the dense interior of stars and planets to the highly rarefied intergalactic medium. These flows share the fact that they are generally turbulent, i.e. highly disordered both in space and time. Turbulence is one of the…

Multiwavelength AGN Surveys and Studies

Multiwavelength AGN Surveys and Studies

AGN surveys are the source for the most interesting objects in the extragalactic Universe: QSOs, Seyfert galaxies, blazars, radio galaxies, LINERs, etc. They are important for understanding the variety of extragalactic sources and their interrelationship, as well as understanding the evolution of the Universe. Recent ground-based and space missions give vast amount of new multiwavelength (MW) data,…
