La distribuzione della materia scura nelle galassie nane

Alcuni astronomi della Università del Texas a Austin ritengono di aver trovato la risposta ad un mistero che dura da circa 20 anni relativo alla distribuzione della materia scura nelle galassie nane. Gli scienziati hanno osservato che la distribuzione, in media, segue una legge molto semplice in cui la densità diminuisce dal centro della galassia, anche…

Multi-Spin Galaxies

Multi-Spin Galaxies

Galaxies are the building blocks of the Universe: thus, in order to trace its evolution history one needs to understand how galaxies formed and evolved, in particular which are the main physical processes that have let to the observed structures.  The "classical" disk galaxies are made by stars, gas and dust which are distributed in…

IAU Symposium 303: The Galactic Center

IAU Symposium 303: The Galactic Center

Scientists are currently are at a crossroads in Galactic center research. Many recent large-scale surveys and wide-field studies of this unique and unusual region of the Galaxy have been made (using Chandra, HST/NICMOS, Spitzer, Fermi and numerous ground based observatories). Such surveys have provided us with multi-wavelength views of the stellar and interstellar environment in…

Anisotropic Universe: from microwaves to ultrahigh energies

Anisotropic Universe: from microwaves to ultrahigh energies

The study of anisotropies connects and unravels fundamental issues in various fields of astrophysics and cosmology. With the recent experimental progress, it is now possible to analyze, understand, and cross-correlate the anisotropic skies observed by Planck, 2MASS Redshift Survey, Chandra, Fermi, AMS-2, HAWC, IceCube, and Auger, - to cite but a few major instruments that scrutinize the Universe…
