Featuring work by SXS member Elias Most (Caltech)! Check out the nice summary in AAS Nova:

There was some kind of Bart Ripperda dynamo at Canadian Institute for Theoretical Astrophysics today…

What happens when a magnetar, a highly magnetised neutron star, collapses into a black hole? Elias Most, Andrei Beloborodov and Canadian Institute for Theoretical Astrophysics faculty Bart Ripperda modelled a rotating magnetar with a magnetic field 15 quadrillion times stronger than Earth’s.

To better understand the extreme physics underlying such a grizzly demise, researchers at Caltech and Canadian Institute for Theoretical Astrophysics's faculty Bart Ripperda are using supercomputers to simulate black hole–neutron star collisions. caltech.edu/about/news/sta…

Why does Air Canada not accept service dogs for psychiatric disorders diagnosed by a doctor? If called for explanations you are just hung up on.... this seems discrimination of people with a non-visible/psychiatric disorder!
