Visitors from Yunnan Observatories

A group of astronomers from Yunnan Observatories, Chinese Academy of Sciences, is visiting the PSO group from September 3 to 7, 2018 to discuss problems in stellar evolution and supernova modelling. The group of visitors consists of Prof. Xuefei Chen, Dr Hailiang Chen and Dr Zhengwei Liu.

PSO alumni meeting

On a perfectly sunny day, we were happy to welcome several former group members at HITS on July 12 for the first PSO alumni meeting. While our guests enjoyed the opportunity to talk about the good old days and discuss new projects, our students used the possibility to learn about different career paths from first-hand…

Mini-Symposium Supernova Observations and Modelling

During the week of July 9-13, the PSO group hosts a number of international guests. Dr Ashley Ruiter and Dr Ivo Seitenzahl from the University of New South Wales Canberra (Australia) are visiting for the full week to continue a long-standing collaboration on thermonuclear supernovae. Furthermore, Magda Siwek and Marc Williamson (New York University, US) will visit…

Visitor: Shing Chi Leung

From July 2-4, 2018, the PSO group hosted Dr Shing Chi Leung from the Kavli Institute for the Mathematics and Physics of the Universe at the University of Tokyo. Shing Chi works on multi-dimensional hydrodynamics simulations to model stellar explosions. During his visit, he presented his latest results on pulsational pair-instability supernovae.

PSO group hosts HJAC colloquium speaker Kate Maguire

From May 22 to 23, 2018, the PSO group hosted Dr Kate Maguire. Kate leads a research group at the Astrophysics Research Centre of Queen’s University Belfast (UK) that deals with explosive transients, cosmology, and supernova progenitors. She visited Heidelberg to give a talk on “Type Ia supernovae: From explosions to cosmology” in the Heidelberg Joint Astronomical…

Visitor: Stefan Taubenberger

From May 17 to 18, 2018, Dr Stefan Taubenberger from ESO Garching visited the PSO group to work on superluminous Type Ia supernovae. Stefan presented his recent work on yet another member of this puzzling sub-class of Type Ia supernovae and we discussed potential explosion scenarios to explain its observational properties.

Visitor: Jakob Nordin

From April  26 to 27, 2018, Dr Jakob Nordin from the Humboldt University Berlin visited us to collaborate on questions regarding the use of Type Ia supernovae as cosmological distance indicators. Jakob and the Cosmology group at HU Berlin are involved in several observational surveys that target Type Ia supernova like the Supernova Factory and…
