Michał Pawlak helped create the first catalog of variable stars from ASAS-SN. Full version of the paper led by Tharindu Jayasinghe is available as arXiv:1803.01001. More variable stars are coming soon!

Visit by Jim Fuller
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.
Seminar at DESY Zeuthen
Visited DESY Zeuthen where I was hosted by Anna Franckowiak and her group. Spoke at Astroparticle seminar.
Observing time on X-SHOOTER
Seminar at University of Delaware
Spent the last couple days at University of Delaware giving a seminar about supernovae and stellar mergers, and talking to Stan Owocki and others.
Visit at Ohio State University
Spent the last week at Ohio State University discussing stellar evolution, transients, binary stars, asteroids, ASAS-SN, and meeting up with Michał Pawlak, who is visiting OSU for a longer period.
Visit at Columbia University
At Columbia today, discussing shocks and dust in stellar mergers, novae and supernovae with Brian Metzger and Elad Steinberg.
Computing time awarded

We are happy to have been awarded CPU time on the Czech national supercomputing center IT4Innovations to study transients from merging stars. Excited to use the fastest supercomputer in the country Salomon, currently ranking 87th in the world.
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.
