DESCRIPTION:Speakers: Prof. Dr. Daniel Siegel\n\nGamma-ray bursts are the 
 most energetic astrophysical events in the universe. They have traditional
 ly been classified into short-duration flashes of less than two seconds\, 
 thought to be associated with neutron-star mergers in binary systems\, and
  long-duration bursts of more than two seconds\, thought to be associated 
 with the collapse of massive\, rapidly rotating stars (collapsars). Their 
 potential to synthesize roughly half of the elements heavier than iron of 
 the periodic table\, has only come into focus more recently. Tremendous pr
 ogress has been achieved since 2017\, initiated with the discovery and int
 erpretation of gravitational waves from a neutron star merger GW170817. Th
 is event generated a short-gamma ray burst accompanied by a radioactively 
 powered optical transient\, known as a kilonova\, which provided direct ev
 idence of heavy-element formation. I will discuss recent theoretical devel
 opments in our understanding of gamma-ray burst events\, including the bri
 ghtest gamma-ray burst of all times\, as well as of observations of multip
 le recent kilonova candidates following gamma-ray bursts. I will particula
 rly highlight how to search for heavy element production and progress towa
 rd elemental identification -- how to use gamma-ray bursts as a key to und
 erstanding the synthesis of elements across a good fraction of the periodi
 c table.\n \n\nhttps://indico.physik.uni-bielefeld.de/event/276/
