About
D. Altmann is a high-energy astrophysicist whose research focuses on the transient universe, particularly the search for neutrino emission from explosive cosmic phenomena. Their key contributions lie in the intersection of multimessenger astronomy and core-collapse supernovae, where they have investigated the role of soft-relativistic jets as potential sources of high-energy neutrinos. Altmann’s most cited work, “Searching for soft relativistic jets in core-collapse supernovae with the IceCube optical follow-up program” (2012, 57 citations), explores the hypothesis that while gamma-ray bursts produce neutrinos in highly relativistic jets, core-collapse supernovae may host softer, less powerful jets that could still generate detectable neutrino bursts on timescales of ~100 seconds. This study leverages the IceCube Neutrino Observatory’s optical follow-up program to constrain jet properties and emission mechanisms. Altmann’s research has advanced our understanding of transient neutrino sources and the role of jets in supernova explosions, contributing to the broader effort of linking gravitational wave, electromagnetic, and neutrino signals. Their work remains influential in the growing field of time-domain astrophysics.
