Rationale (Greek version)

About every 5 years in the village of Kerastari in the ancient region of Arcadia in Greece experts in radio astronomy from all around the world meet to discuss their latest scientific discoveries and astronomical techniques. (see previous workshops in 2002, 2007, 2012 )

The next workshop, at the end of May 2017, will explore how radio astronomy has enabled flexible processing environments that are opening new windows on the Universe (discovery of FRBs is the prime example) and may open others (e.g. SETI). How have unexpected discoveries unfolded in a technical sense and in the new/traditional fora for scientific debate? Has anything benefited the process or held it back?

As we enter the era of the SKA, are we prepared for the technical challenges and, more importantly, do we have people prepared for serendipity? Or are we preparing a generation of SKA users to blindly extract data from catalogues to produce plots? Do these questions matter?

* Cultural changes?



Workshop Location and Venue

The meeting will be held in the Peloponese region of Greece, in the village of Kerastari, nestled in the mountains of ancient Arcadia (close to the town of Tripolis). Time will be scheduled for discussion and interaction, as well as relaxation. The workshop will end with a large party involving the whole village.

Participation at the workshop will be limited to ~80 people due to the size of the venue. As a result some selection may be necessary. Naturally, preference will be given to participants with contributions accepted by the SOC.
All interested in participating, and especially if proposing a presentation, are encouraged to pre-register as soon as possible via the web pre-registration form.

Workshop fees, payments and assistance

The registration fee will be ~E300 for non-students and ~E150 for students and retirees. It covers the reception, light breakfast, lunch and coffee/tea every workshop day, the conference dinner, daily bus transport and publication expenses.

As the workshop is mainly self-funding with limited sponsorship, ALL participants are expected to pay registration, including invited speakers and LOC and SOC members.

In exceptional circumstances, some limited financial support may be possible. Please email directly to the workshop LOC.

** Following generous sponsorship from many institutions (see logos at the beginning of this page), including by the local government organisations, there will be no registration fees for approved Greek participants.

** Payments for registration will be in Euro and must be paid in cash during registration at the workshop. We regret that we have no facilities for credit card payments. There are many ATMs in town. (If anyone wishes to pay by direct bank transfer, email the worskshop LOC for bank details).

Accommodation costs are not included and must be paid directly to the hotels by the participants. Links to details on hotels and transportation are included in these webpages.

If an official invitation is needed for visa or other purposes, again email the workshop LOC.
