A&A Survey to Understand Publishing Needs of the Astronomical Community

As part of A&A’s ongoing commitment to our authors and readers, Astronomy & Astrophysics has launched a short survey to better understand the publishing needs and priorities of our community.

In a rapidly evolving landscape of scientific publishing, it is more important than ever for A&A, a journal for astronomers by astronomers, to listen carefully to the community it serves. This survey explores key issues including open access, peer review, the role of AI, and journal selection criteria.

Shaping a sustainable future for A&A: new policy on paper length

Since 2022, the Astronomy & Astrophysics Journal (A&A) has been published in open access under the Subscribe to open (S2O) model conditional on the renewals of library subscriptions, allowing unrestricted access to all papers published in the journal, regardless of geographic or economic barriers. We are strongly committed to maintaining this policy in the future, and continuing to publish A&A as a journal by astronomers, for astronomers.
