Some of the biggest mysteries of physics – including the nature of dark matter and dark energy, and the origin of the universe – are in the sights of cosmologists and astroparticle physicists.

In this episode of the Physics World Weekly podcast I am in conversation with three editorial board members of the Journal of Cosmology and Astroparticle Physics (JCAP) which is celebrating its 20th anniversary.

They are the cosmologist and theoretical physicist Licia Verde who is at the Institute of Cosmos Sciences at Spain’s University of Barcelona; Erminia Calabrese, who is an observational cosmologist at the UK’s Cardiff University; and the astroparticle physicist Anne Green, who is at the University of Nottingham in the UK.

We chat about major breakthroughs in cosmology and astroparticle physics over the past two decades and look forward to the future of the fields.

This podcast is sponsored by the Electrochemical Society.

JCAP has published a special retrospective collection of some of the leading papers that have been published in the journal since 2003. Next week, the journal will publish a special anniversary issue of new papers.
