Hello, my name is Erk Kangra. I'm a Collegium Researcher at TCSM, the Turku Collegium for Science and Medicine. And I'm based at the Department of Physics and Astronomy here at the University of Turku. And the TCSM position has really allowed me to concentrate on carrying out my own research, which focuses on various types of astrophysical transients, in particular co-collapse supernova explosions, that end the life cycles of the most massive stars. I'm also interested on the usage of co-collapse supernovae as probes of the cosmic star formation history of the universe. In my work, I'd make use of data, for example, from the Nordic optical telescope and the facilities of ESO, the Europeans are an observatory. Recently, I have also focused on the new field of multimessantial astronomy, which is making use of, for example, gravitational wave and high energy cosmic neutrino detections, in addition to conventional astronomy observations that are carried out at electromagnetic wave ends.
