The INAF Istituto di Radioastronomia , with the financial support of RadioNet, is organizing a Workshop on Rotation Measure Analysis of Magnetic Fields in and around Radio Galaxies.
Scientific Rationale
Magnetic fields in groups and clusters of galaxies regulate thermal conduction and influence the dynamics of bubbles and cavities. In radio galaxies, they are essential to the production of synchrotron radiation and to most models for the collimation and acceleration of relativistic jets. Multifrequency radio polarization observations have recently led to important new results on foreground magnetic fields on parsec and kiloparsec scales. This area of research is about to take a major step forward with the commissioning of a new generation of instruments operating at centimetre and metre wavelengths: EVLA, e-MERLIN and LOFAR.This specialised Workshop will focus on the analysis of multifrequency radio polarization imaging to derive magnetic fields in thermal plasmas along the line-of-sight to radio galaxies and quasars. Its aims are to take stock of the current state of the field, to compare different methods of analysis, to provide a forum for theorists and observers to interact and to prepare for observations with the new generation of arrays.
Topics will include:
- Algorithms for analysis of Faraday rotation data, including rotation-measure synthesis.
- Approaches to measuring the spatial statistics of rotation-measure fluctuations, such as structure functions and Bayesian methods.
- Magnetic fields in individual elliptical galaxies, groups and clusters; trends and differences.
- Coherent RM structures and their implications.
- Theory of magnetic-field generation and evolution in groups and clusters.
- The effects of interaction of radio galaxies with the surrounding medium.
- Implications for heating and cooling of groups and clusters.
- Observations of Faraday rotation on parsec scales.
- Theoretical models; implications for jet formation and collimation.
There will be no published proceedings, but all presentations and posters will be made available on the conference web site.
Workshop Location and Venue
The location of the Workshop will be the seaside resort of Riccione, Italy. The Workshop will start with registration in the evening of May 10th and will end at noon on May 14th, 2010. The venue is the Hotel Lungomare where participants to the meeting will be accommodated as well.Registration
The registration fee includes: welcome dinner, hotel accommodation, Conference dinner.
The Workshop will start with registration and welcome dinner on Monday 10th. The hotel accommodation includes half board (breakfast + lunch) for 4 nights, excluding the lunch on Friday 14th. Please note that the accommodation dates for the Workshop are fixed: if you want to arrive earlier or stay longer please contact the Hotel Lungomare directly.
The normal registration fee is 550 Euro if paid before March 1st, 600
Euro if paid later. This covers accommodation in a single room.
Some RadioNet funds are available to support travel and accommodation for
a small number of participants, for whom a lower fee of 450 Euro is
applied and the accomodation will be in double rooms
to be shared with another participant.
Radionet grants are intended primarily for young
scientists (students and junior postdoc) based in the European Union, but a
special case can be made for support of one or two participants from
outside the EU.
Those granted support are required nonetheless to pay the full
registration fee of 550 Euro before March 1st 2010: reimbursement will be
made by RadioNet after the Workshop.
The number of participants is limited to about 50 persons, thus we encourage early registration.
Important dates
- Deadline for pre-registration: December 14th, 2009.
- Early payment (discounted fee): March 1st, 2010.
- April, 1st, 2010: end of registration.
