Science and Technology of
Long Baseline Real-Time Interferometry:
The 8th International e-VLBI Workshop
22-26 June 2009 - Madrid, Spain
The Centro Nacional de Informacion Geografica - Instituto Geografico Nacional
(CNIG-IGN) of Spain, in cooperation with the EXPReS project, is pleased to
host the 8th International e-VLBI Workshop, 22-26 June 2009, at the premises
of the National Astronomical Observatory in Madrid, Spain.
In recent years real-time, long-baseline, radio interferometry over optical networks
has developed from a technical possibility to a mature technique. Scientifically,
real-time operation is more important for long baselines, with their high spatial
resolution, than for short baselines. However, until recently the required technology
has not been readily available. Technical advances and the explosive increase of
connection capacity have now radically changed the situation. Emerging radio interferometers
(e-MERLIN, E-LOFAR, e-EVN and other e-VLBI arrays) will exploit mixed private/shared networks
to achieve wide-bandwidth real-time operation. Mirroring developments in other wavebands of
astronomy, these new real-time radio instruments are being optimised to study transient
phenomena. Moving data transport to fibre also gives the prospect of rapidly expanding
observing bandwidth and sensitivity as network capacity continues to increase. Technically and
operationally today's e-VLBI instruments serve as precursors to the real-time Square Kilometer
Array. Given recent developments the time seems ripe to bring all those working on
the science and technology of real-time, long-baseline radio interferometry together
to discuss the state-of-the-art and future prospects.
The week long conference will cover both scientific applications (first half) and technical
implementation (second half) with joint sessions in the middle. Participants are welcome
to attend a part or the whole of the conference. The conference proceedings will be published
electronically. Specific areas to be covered include:

Applications of real-time operation to astronomy,
geodesy and other applications. How to best coordinate emerging
e-VLBI arrays for best scientific return. Connections to transient
monitoring in other wavebands including Fermi Gamma-Ray Space
- Technical: e-VLBI test experiments, use of new long distance links,
development in techniques including selective packet dropping and
novel protocols, the search for higher bandwidths, network status
and monitoring, distributed processing, and future development.
- Scientific/Technical: Future technical possibilities of interest in
planning future instruments. Desired technical requirements to
fulfill scientific goals, science priorities for development.
