In response to the likely call for missions by ESA at the end of this year, INAF, SRON and ISAS are
preparing a proposal which combines telescopes with a large field of view and fast repointing.
The main scientific drivers for this mission are the
study of large scale structures:
the Warm-Hot Intergalactic Medium and clusters (evolution, physics and surveys), and the use of
GRB as cosmological
probes. Other interesting fields with a high promise include the extreme physics in compact objects
(e.g. Equation of State of Neutron stars), the study of large populations (AGN including their variability, Blazar,
galaxies, …) and extended sources (clusters, SNRs).
The current mission concept includes three main instruments: a Low-Energy telescope with excellent energy
resolution, a High-Energy Telescope which combines high angular resolution with an extended energy
range at the expense of the energy resolution and a Wide Field Monitor which will trigger the fast repointing
(~ minute)
and has an energy response up to 1 MeV. This mission can be implemented in the small/medium class category of ESA.
The key characteristics of these instruments is listed below.

The purpose of the meeting is to solicit ideas from the community to improve the science case and explore
if the currently planned payload is addressing the most important questions in our field.
In addition to presentations by the study team about the science and mission concept, there
will be room for contributed talks from the high-energy community addressing scientific and
instrumental enhancements.
There is no registration fee.
Information about the location (CNR headquarters) and accommodation
are provided by these
pages.
