Dear Colleagues,

We would like to thank you again for your interest in the workshop on High Energy Phenomena in Relativistic outflows (Dublin, Sep 24-28, 2007). In order to complete the program we ask you all to register and send the title/abstract of your presentations (this concerns also the INVITED talks) before August 1st. If you have registered, you should have received a confirmation email by now. Also note that we established a prepayment scheme for the registration fee through a bank transfer with a reduced fee of 220 Euros, if paid before August 24th.

Finally we recommend you to book hotels as soon as possible. The cheapest way would be if you make reservations by internet - you can sometimes find attractive discounts when booking on the Internet. There is also a block of reserved rooms at Trinity College and in nearby hotels. You can find accommodation instructions on our workshop webpage:

Note that we have a limited offer of *very* reasonably priced accommodation to be found at Trinity College, to be booked through

We look forward to seeing you in Dublin.
Best regards,
