Welcome to the University of Sydney’s Astroparticle physics group, led by the Head of the School of Physics Prof. Céline Bœhm. We conduct research that connects the otherwise disparate worlds of astronomy, particle physics, and cosmology. We are principally interested in studying some of the most important issues with our understanding of the Universe, such as the identity of dark matter, the conditions of the early Universe, the formation of large scale structure, the properties of high energy cosmic rays, and the nature of gravity.
We are one of the five nodes of the ARC Centre of Excellence for Dark Matter Particle Physics (CDMPP).
We also overlap in membership with the Sydney Institute for Astronomy (SIfA), the Particle Physics group, and a Sydney-UNSW joint venture: the Sydney Consortium for Particle Physics and Cosmology (CPPC).
- Ciaran O’Hare and Celine Boehm’s recent publication “Particle detection and tracking with DNA” was featured in an article in the New Scientist
- Ciaran O’Hare’s recent article “New definition of the neutrino floor for direct dark matter searches” was selected as a highlighted article and Editor’s suggestion in Physical Review Letters
- Celine will be giving a seminar at the IAP, and will also speak at the Light Dark World 2021 international forum
- Zac gave a talk and presented a poster at AstroDark-21
- Dr Ciaran O’Hare has been awarded a $400,000 DECRA for the project “Unmasking dark matter: from the laboratory to the Milky Way”.
- The group attended the Dark Matter Centre’s Annual workshop, in which Zachary Picker gave a talk on his work on the “companion axion model”. Zac and Markus also both presented posters at the meeting.
- Zac Picker gave a seminar for our CPPC series on his PhD work, which can be viewed here
- Ciaran O’Hare is giving seminars at Tsung-Dao Lee Institute, Melbourne University, UC San Diego, University of Goettingen, and Nanjing Normal University on his recent work on the neutrino fog.
