RATIONALE AND PROGRAM
---------------------
Recent years have seen an increasing interest of the astronomical
community on the topic of super-Eddington accretion on compact
objects, which can apply to a variety of systems, such as
supermassive black holes, black hole binaries, ULXs, neutron
stars. The possibility that the Eddington limit may be violated
can have important implications for the related topics of
black hole growth, galaxy evolution and AGN feedback.
After two years from the first edition of Breaking the limits,
we reconvene to discuss the advancement done in the last two years.
This workshop will be an opportunity to compare recent observations
with state-of-the-art theoretical modeling of super-Eddington flows,
and to discuss the cosmological implications of this regime of
accretion.
LIST OF SESSIONS:
-----------------
Accretion and ejection physics
Black hole growth and galaxy evolution

VENUE
-----
The conference will be held at the Sant’Elmo Beach Hotel,
in Castiadas (CA), a small town along the beautiful East
coast of Sardinia, in Italy. This resort offers a variety
of lodging solutions and discounted prices for conference
participants. Please reserve your room as soon as possible

SOCIAL EVENTS
-------------
Besides the traditional social dinner, during this workshop
it will be possible to visit to the recently commissioned
Sardinia Radio Telescope (http://srt.inaf.it), a 64-m
antenna for Radio Astronomy, Geodynamical studies and Space
science, with active surface and cutting-edge technology,
able to work either in single dish or in VLBI mode.
