The Near-Field / Deep-Field Connection

The Near-Field / Deep-Field Connection

The Southern California Center for Galaxy Evolution (CGE) and the University of California High-Performance AstroComputing Center (HiPACC) are bringing together theorists and observers for a three-day conference on the Near-Field Deep-Field Connection. Topics of the workshop to be covered will include: local relics of reionization, connections between first stars and local metallicity, the evidence for…

Astrophysical Black Holes

Astrophysical Black Holes

Black holes are very fascinating and peculiar objects. According to General Relativity, uncharged black holes are completely specified by only two parameters, the mass M and the spin angular momentum J. In the last 40 years, we have discovered at least two classes of astrophysical black hole candidates: stellar-mass objects in X-ray binary systems and…

The need for a new, giant particle collider

Al CERN di Ginevra sono pronti per lanciare una nuova sfida, ancora più grande. E' quanto hanno affermato in questi giorni i fisici delle particelle che oggi come non mai ritengono necessaria la costruzione di un nuovo, gigantesco acceleratore, almeno sette volte più potente dell'attuale Large Hadron Collider (LHC) grazie al quale è stato possibile rivelare…

Earth-like planets could not be the right places for life

E' quanto afferma l'astrofisico René Heller del McMaster’s Origins Institute secondo il quale la vita extraterrestre potrebbe essere presente su un'altra categoria di pianeti molto diversi da quelli terrestri che non sarebbero, così, il posto ideale dove può emergere la vita, almeno come noi la conosciamo. Questi mondi alieni detti "super abitabili" avrebbero una massa due o…

Exoplanet Observations with the E-ELT

Exoplanet Observations with the E-ELT

Exoplanet research is one of the major science drivers for the future 39-m European Extremely Large Telescope (E-ELT). A comprehensive suite of instruments will provide the community with the ability to conduct a wide range of outstanding exoplanet science programmes. In addition, some combinations of instruments will indeed be more powerful than the sum of the…

Unveiling the Formation of Massive Galaxies

Unveiling the Formation of Massive Galaxies

Recent observations have delivered new insight into the structure and evolution of massive galaxies. Once thought of as relatively simple systems, it is now clear that these galaxies are diverse and can contain multiple stellar populations. Their assembly was a drawn-out process influenced both by the dark matter halos which surround them and the supermassive…
