A new window on the radio emission from galaxies, clusters and cosmic web

The current radio astronomical interferometers, such as, for instance, LOFAR, ASKAP, MeerKAT, JVLA, uGMRT, and MWA, which are paving the way to the SKA, are providing breathtaking advances in our view of radio galaxies, galaxy clusters, and cosmic web.

The image quality and fidelity of the present observational facilities, as well as the state-of-the-art numerical simulations are unveiling unexpected details, which are challenging our knowledge.

It is timely to review our current understanding and open questions of the radio galaxy phenomenon, the relation between radio galaxies and the surrounding environment, and of the origin of diffuse emission in galaxy clusters and beyond.

The aim of this meeting is to review our knowledge in this field of research, present the new challenges we are facing and discuss scientific prospects over the next decade, in the light of the capabilities of the SKA. We encourage submissions related to the following topics:

- Peculiar radio emission associated to radio galaxies in different environments;

- New and/or new features and properties of diffuse radio sources in galaxy clusters;

- Non-thermal component outside galaxy clusters.

You can find a description of the Special Issue together with all the relevant information here.

In particular, we report the Manuscript Submission Information as written by the Galaxy Editorial Board below:

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Galaxies is an international peer-reviewed open access quarterly journal published by MDPI.

The RCGW meeting is organised to share and discuss new scientific results in an enjoyable and productive atmosphere, where everyone can feel comfortable and free to express opinions. We therefore expect all participants to behave professionally and be respectful of other colleagues at all times, regardless of gender, sexual orientation, disability, physical appearance, body size, race, nationality or religion. Any form of harassment, bullying and discrimination will be not tolerated at the meeting. Every attendee is expected to make their individual contribution towards a positive and inclusive working environment.

Please follow these guidelines:

Behave professionally. Harassment and sexist, racist or exclusionary comments or jokes are not appropriate. Harassment includes sustained disruption of talks or other events, inappropriate physical contact, sexual attention or innuendo, deliberate intimidation, stalking, and photography or recording of an individual without consent. It also includes offensive comments related to gender, sexual orientation, disability, physical appearance, body size, race or religion.

All communication should be appropriate for a professional audience including people of many different backgrounds. Sexual or sexist language and imagery is not appropriate.

Be considerate and respectful towards others. Do not insult or put down other attendees.

All forms of social media should be used responsibly, respecting both individuals and the organization hosting the meeting.

Individuals asked to stop any inappropriate behavior are expected to comply immediately. Anyone violating these rules may be asked to leave the event at the discretion of the organizers. Any participant who wishes to report a violation of this policy may do so in confidence by speaking to any member of the SOC.

Can I submit a talk about a work which I recently published?

The aim of this conference is to stimulate the submission of manuscripts for the associated Galaxies Special Issue. Following the publication rules of the journal you have to submit original contributions. You can propose a talk about your published work and therefore a manuscript to Galaxies (which is customary for all the speakers) if there are new contents. For example, if you will analyse some aspects which were not deeply investigated in your original paper, or if you will offer a new interpretation of the data, or again if new data can improve your results, then we definitely suggest you to propose a talk and submit a manuscript. Please, visit the Instructions for Authors page of Galaxies before submitting a manuscript.

Can I present a talk and submit a manuscript even if the results are still preliminary?

Yes, we encourage to present preliminary results.

Can I present a talk without submitting a manuscript to Galaxies?

No. This conference has been organized to stimulate the submission of manuscripts for the associated Galaxies Special Issue. All the speakers should submit a contribution to the Special Issue.
