New focus section on cosmological perturbations in Classical and Quantum Gravity

It is with great pleasure that we announce the publication of the following focus section in Classical and Quantum Gravity (CQG):

Focus section on non-linear and non-Gaussian cosmological perturbations, dedicated to the memory of Lev Kofman
Guest editors: Misao Sasaki and David Wands

In recent years there has been a resurgence of interest in the study of non-linear perturbations of cosmological models. This focus section will be of interest to theoretical physicists and astrophysicists alike interested in understanding and interpreting recent developments in cosmological perturbation theory and models of the early universe. The section is dedicated to the memory of Lev Kofman (1957–2009), an enthusiastic pioneer of inflationary cosmology and non-Gaussian perturbations.

This is CQG’s first ever focus section.  A focus section is a collection of specially invited papers on a subject of current interest.  Unlike other special issues, it is not based on a conference.  We are sure you will agree with the referees of the issue who reported that the contributions are timely and of a very high quality.

We take this opportunity to thank all of the authors, referees and particularly the guest editors who gave their time and expertise to create this excellent issue.

The focus section will be free to read for 6 months from date of publication.  We invite you to read the articles on the new IOPscience service!

Yours sincerely,

Adam Day
