Technical working group on IMAGINE infrastructure.
Coordinator: Sebastian Hutschenreuter
Members: Tess Jaffe, Jiaxin Wang, Vincent Pelgrims, Ellert van der Velden
Description: IMAGINE infrastructure continued development and maintenance. Developing the testing and CI framework for infrastructure and contributed modules. Write a software standard following the CRPropa model. Depends on IMAGINE infrastructure.
Galactic cosmic ray distribution
Coordinator: TBD
Members: Arjen van Vliet, Jiaxin Wang, Tess Jaffe, and Carmelo Evoli
Description: Galactic cosmic ray distribution (spatial and spectral) and propagation. Depends on IMAGINE infrastructure.
Connecting CRPropa to IMAGINE
Coordinator: Arjen van Vliet
Members: Jörg Hörandel, Francesca Capel, Stefan Hackstein
Description: Connecting CRPropa to IMAGINE. Depends on IMAGINE infrastructure.
Statistical characterization of MHD simulations
Coordinator: François Boulanger
Members: Tess Jaffe, Anvar Shukurov
Description: statistically characterizing MHD simulations to formulate sub-grid modeling and efficient random field simulation. Includes IMAGINE infrastructure.
Supernova remnants (merged with working group 8)
Coordinator: Jennifer West
Members: Anvar Shukurov, Luiz Rodrigues
Description: The shape and magnetic field structure of supernova remnants contain a signature of the global Galactic magnetic field that they were created in. The increasing amount of radio-polarimetric data on numerous supernova remnants allows us to trace back the Galactic magnetic field from their properties.
Local Bubble
Coordinator: Katia Ferrière
Members: François Boulanger, Marijke Haverkorn, Vincent Pelgrims, Vibor Jelic, Torsten Enßlin
Description: Local bubble in GMF modeling including 3D tomography with Gaia dust extinction as well as Faraday tomography. IMAGINE infrastructure.
Starlight polarization
Coordinator: José Versteeg-Veltkamp
Members: Marijke Haverkorn, Torsten Enßlin, Sebastian Hutschenreuter, Vincent Pelgrims, Yenifer Angarita
Description: Interstellar polarization of starlight is a valuable additional tracer of the GMF. With GAIA DR2, starlight polarization add 3D information to other tracers to almost all are line-of-sight integrated throughout the Milky Way. The end goal is including starlight polarization data into the IMAGINE infrastructure. Shorter-term goals are investigating what GMF information can be gleaned from starlight polarization.
Faraday rotation and helicity (merged with working group 5)
Coordinator: Jennifer West
Members: Tess Jaffe, Torsten Enßlin
Description: Faraday rotation and helicity. May use IMAGINE infrastructure
Polarized dust emission
Coordinator: Vincent Pelgrims
Members: Tess Jaffe
Description: Development and test of an IMAGINE module intended to produce simulated polarized thermal dust emission observables for IMAGINE infrastructure.
Dust absorption (sleeping/absorbed in wg 7 and 9)
Coordinator: Marijke Haverkorn
Members: (Vincent Guillet), Vincent Pelgrims, François Boulanger
Description: this is a follow-up project to the "Polarized dust emission" project above, which wants to include a module with thermal dust emission characteristics. These should be closely matched to the dichroic absorption mechanisms of that same dust, which we are going to need for project "Starlight polarization and synchrotron" in the end as well.
Integrate PRISM into IMAGINE
Coordinator: Ellert van der Velden
Members: Luiz Rodriques
Description: Use PRISM to speed-up the sampling that is used in IMAGINE.
IMAGINE infrastructure.
Low-frequency radio diffuse polarimetry
Coordinator: Vibor Jelić / Marijke Haverkorn
Members: Marco Iacobelli, Luka Turić
Description: Depolarization canals in low-frequency Faraday depth cubes can have various origins, some of which carry information about the interstellar medium. This project aims to study these depolarization canals and their relation to other tracers of (local) interstellar magnetic fields to understand these local fields better.
Fast Radio Bursts
Coordinator: Stefan Hackstein
Members: Luiz Rodrigues
Description: Detection of a huge number of FRBs with RMs is expected for the coming decade. We investigate how FRBs, esp. their RMs, can be used in order to gain information, additional to those from persistent sources of RM, on Galactic fields.
Constraining and extending the GalMag model
Coordinator: Luiz F. S. Rodrigues
Members: Anvar Shukurov, Tess Jaffe, Luke Chamandy
Description: Integrate the GalMag GMF model to the IMAGINE pipeline; examining constraints imposed by observational data; extending the model to account for magnetized winds. Depends on IMAGINE infrastructure.
