The Power of Faraday Tomography: Towards 3D Mapping of Cosmic Magnetic Fields

28 May – 2 June 2018, Miyazaki, Japan

A very rewarding conference was held in Miyazaki, Japan, organised by SKA-JP. In addition to a comprehensive science program, the conference featured tutorial sessions teaching modern radio polarimetric techniques, an ASKAP POSSUM workshop, and even a karaoke session! Proceedings of the conference will be published in a special issue of Galaxies.

Upcoming conferences

Sixth annual CHANG-ES collaboration meeting
30 July – 4 August 2018, Calgary, Canada

CHANG-ES is the Continuum HAlos in Nearby Galaxies – an Evla Survey. CHANG-ES is a survey of edge-on spiral galaxies that reveals the interaction between the star forming disk and the extended halo. CHANG-ES observed 35 edge-on galaxies in the local universe with the Jansky Very Large Array in L band (1-2 GHz) and in C band (5-7 GHz). Follow-up observations at other wavelengths have been made or are in preparation. The 6th annual CHANG-ES collaboration meeting will be held in Calgary, July 30 to August 4, 2018. The meeting is open to members of the CHANG-ES consortium and other participants by invitation.

IAU General Assembly Focus Meeting 8: New Insights in Extragalactic Magnetic Fields

29-31 August 2018, Vienna, Austria

The coming years and decades will see a burst in our information and understanding of extragalactic magnetic fields due to the next generation of radio astronomy facilities, especially the SKA and its precursors, as well as major advances in MHD numerical simulations and algorithmic improvements to extract magnetism information from the databases. The Focus Meeting will be the moment to discuss the challenges and opportunities for understanding the magnetized Universe from scales of galaxies to the cosmic web and connect information across the spectrum.

IAU General Assembly Focus Meeting 4: Magnetic fields along the star-formation sequence

30-31 August 2018, Vienna, Austria

It is believed that magnetic fields play important roles in star formation processes, in particular to overcome both the angular momentum and magnetic flux problems. Polarimetry from the optical to the centimeter wavelengths has been the most powerful observing technique to study magnetic fields: in this Focus Meeting we wish to bring together communities working with polarimetric observations of the various stages and objects along the star formation sequence, from the structure of star-forming molecular clouds to the arrival of young stars on the zero-age main sequence. The goal is to discuss how to compare observations of magnetic fields at different evolutionary stages and physical scales such that we can establish a coherent view of their key role in the multi-scale process of star formation. Combining results from different fields is complex, and thus we will emphasize how different measurements of the magnetic fields can be compared and interpreted into a coherent picture despite widely varying observing techniques, and the very different objects and physical scales that are probed.

LOFAR Magnetism Key Science Project annual meeting

10-14 September 2018, Kraków, Poland

The 2018 Annual Meeting of the LOFAR Magnetism Key Science Project will take place in Kraków, Poland. The meeting includes two days of science presentations, and 3 Busy Days. The meeting is organised by the Astronomical Observatory of the Jagiellonian University, and will be hosted in the main building of the Faculty of Physics, Astronomy, and Applied Computer Science. The purpose of this meeting is to present recent science results obtained with LOFAR, discuss future work of the MKSP within the LOFAR project, as well as other related tasks.

“New Perspectives on Cosmic Magnetism”: Special Issue of the journal Galaxies

We invite you to submit manuscripts for a Special issue of Galaxies on “New Perspectives on Galactic Magnetism”. Rapid improvements in the observing capabilities of radio telescopes and in the physical realism of numerical simulations, as well as growing activities due to the Square Kilometre Array and its pathfinders, suggest to us that an overview of the current state of the field would be useful and timely. This Special Issue aims to provide a platform to facilitate effective communication between observers, theorists and simulators to advance our field in new directions. It will contain both critical reviews and current research articles on new developments in all aspects of galactic magnetism. We particularly welcome contributions on: The connection with other components of the interstellar medium, including cosmic rays; the use of numerical simulations to help interpret observations; revisiting and addressing common assumptions used in the field; new observational techniques and recent advances in numerical simulations. The deadline for manuscript submission is January 31, 2019. For manuscript submission instructions, please see http://www.mdpi.com/journal/galaxies/special_issues/GalacticMagnetism . Please contact guest editors Sui Ann Mao (mao@mpifr-bonn.mpg.de) and Andrew Fletcher (andrew.fletcher@newcastle.ac.uk) for any questions.
