Observations and modelling of the inner heliosphere: Preface and tribute to the late Dr. Andy Breen

Abstract

It is a pleasure to acknowledge the Editors and staff at Solar Physics for their work in pulling this Topical Issue (TI) together, and thanks again to the team of referees for their time and effort in making this a very successful TI, covering a broad range of topics and studies related to observing and modelling the inner heliosphere. Special thanks also go to colleagues and friends of the late Andy Breen, but especially to Shelley Upton (a dear and long-time friend of Andy’s), Andrew Rawlins (a very close friend of Andy’s) of Aberystwyth University for providing various photographs and stories of Andy, of his various hobbies and interests and other aspects of his personal life, as well as to Michael Lockwood of the University of Reading, who kindly researched and wrote various tributes/obituaries to Andy, on which some of the material here was based. We also like to thank Aberystwyth University (AU) for providing the rooms and internet access for the Workshop as well as the Institute of Mathematics and Physics (IMAPS) at AU for providing funding towards the refreshments in the mornings and at break times throughout the workshop.
