Rationale

High-energy astronomy is a blossoming field with plenty of results from the current very successful generation of high energy instruments which perform flawlessly in space as well as on the ground.
The high-energy space armada can count on Chandra and XMM-Newton, both launched in 1999, Integral (2002), Swift (2004), Agile (2007), Fermi (2008) and NuStar (2012). By complementing each other, all these missions are invaluable assets to discover and to understand all kinds of high-energy sources from fractions of keV to hundreds of GeV, be they steady or variable, galactic or extragalactic, point-like or extended.
At energies above 100 GeV, where space instruments become “photon-starved”, owing to their limited collecting area, ground based Cherenkov telescopes become essential for adding the very high-energy view on both galactic and extragalactic sources. VHE astronomy, both in pointing and in transit mode, is still in its infancy and many more results can be expected in the near future, also owing to the multimessanger approach which is being tested now for tomorrow.
After reviewing the current state on the High-Energy Universe and, within it, discussing the many unsolved problems astronomers are now confronted with, we will focus on the prospects of high-energy astrophysics, keeping in mind that the longer-term future will certainly offer a new and different portfolio of instruments.
With no major new gamma-ray space mission in sight, the focus of the field is bound to shift towards ground based techniques. Such a shift, driven by the Cherenkov Telescope Array development, will likely open a new discovery space, thus changing our view of the High-Energy Universe.

So far, Giovanni Bignami (Italy), Brenda Dingus (US), Neil Gehrels (US), Isabelle Grenier (France), Dieter Hartman (US), Werner Hofmann (Germany), Chryssa Kouveliotou (US), Marco Tavani (Italy), have accepted to serve in the Symposium SOC .

The LOC will be chaired by Giuseppe Malaguti

The location will be the Research Area in Bologna, easy to reach from the airport as well as from the Railway station, with a meeting room with 400 seats and ample space for coffee and lunch breaks as well as for poster sessions.
