Pushing the limits of Faraday rotation

LOFAR MKSP:



Galaxy halos and outer disks:
ne 10-3 cm-3, B 1 G, L 1 kpc: RM 1 rad m-2



Intergalactic filaments:
ne 10-4 cm-3, B 0.1 G, L 10 kpc: RM 0.1 rad m-2


Detection of weak magnetic fields
in the Milky Way, nearby galaxies and in the intergalactic medium

LOFAR MKSP:

Targets:


Galactic sources: polarised Galactic regions (Fan, NPS); SNR, HII & planetary nebulae as Faraday screens Nearby galaxies: spiral, barred, edge-on, dwarf, interacting, blue compact, Virgo cluster members Intergalactic filaments, e.g. in galaxy groups Polarised giant radio galaxies Polarised pulsars Polarised stellar and AGN jets

This workshop


Rollout of stations will start soon Commissioning observations can start in summer Million Source Shallow Survey (MSSS) will start at the end of 2009

A lot of work needs to be done during next months: Develop and test software for pol calibration, RM Synthesis and source finding Plan and conduct commissioning observations Organise data storage and analysis Write documents: scientific Project Plan and Proposal, technical Use Case and Calibration Document
