Open positions

So you want to be an astronomer?

We are seeking to fill 1-2 PhD students positions funded by the Primus award to begin in September 2018 and lasting 4 years. We are interested in observational or theoretical aspects of time-domain astrononomy. Possible topics include core-collapse supernovae, stellar mergers, eclipsing binaries, variable stars, stellar dynamics, (magneto)hydrodynamics, radiation transport, “big data”, etc. Many of these issues are directly related to the important unsolved problems of contemporary astrophysics. The group has access to the All-Sky Automated Survey for Supernovae (ASAS-SN). The candidates are expected to work within international collaborations. Continue reading “Open positions”

In the past couple days we hosted Jim Fuller from Caltech, who gave talks at our departmental seminar and at the Astronomical Institute of the Czech Academy of Sciences.

The Antesonic Condition for the Explosion of Core-Collapse Supernovae by Raives et al.

Matthias Raives et al. studied transition from accretion to explosion in highly idealized setting of the neutrino mechanism of core-collapse supernovae and in relation to the critical neutrino luminosity of Burrows & Goshy (1993) and extending the previous work of Pejcha & Thompson (2012). Interestingly, in order to properly resolve the vicinity of the critical transition, high simulation resolution is needed.
