New work led by Amy Secunda and Yan-Fei Jiang Flatiron CCA, using multi-frequency radiation MHD simulations to test the physical basis of reverberation mapping in Active Galactic Nuclei. TLDR yes it should work, pretty well, but not in every circumstance. arxiv.org/abs/2501.06304







simonsfoundation.org/2025/04/29/fla… Direct evidence magnetar giant flares eject neutron star crust material capable of heavy element nucleosynthesis and associated kilonova-like signals . As the gamma-ray signal came from the 2004 giant flare, in some since this was the "first" kilonova.



With Brian Metzger and others, we discovered a new site of heavy element (r-process) nucleosynthesis! Main points nicely summarized below.
