Our results highlight the importance of self-consistent, long-term modeling of merger ejecta, and the importance of taking viewing-angle dependence into account when interpreting observed kilonova lightcurves. We find that magnetized outflows from a neutron-star remnant could explain blue kilonovae.

We investigated three remnant lifetimes and different r-process heating prescriptions to explore the impact on kilonova lightcurves and spectra.

We followed up GRMHD simulations of binary neutron-star merger remnants and their outflows via long-term 2D FLASH simulations and once homology is reached, performed SEDONA radiation transport to obtain lightcurves and spectra.

Fun visit to the @einsteintelescope.bsky.social pathfinder at @maastrichtu.bsky.social yesterday with my research group. Really cool developments in the making, thanks very much for the great tour! #highenergyastro

There lots more work to do to evolve the simulation for longer after black-hole formation but for now it is really cool to measure the mass and spin of the newly-born black hole directly!

Super exciting proof-of-principle work with GRaM-X lead by @gonihalevi.bsky.social following a 45 solar-mass low-metallicity progenitor star all the way to black-hole formation in full Numerical Relativity.

Led by former API PhD student Swapnil Shankar, we performed 12 MHD-driven core-collapse supernova simulations and systematically study the conditions under which jets can be successfully launched varying initial rotation rates and magnetic fields.
