His main research concerns Astrophysics, Astronomy, Gamma-ray burst, Galaxy and Redshift. His study in Fermi Gamma-ray Space Telescope, Light curve, Star formation, Telescope and Supernova is carried out as part of his studies in Astrophysics. Jochen Greiner works mostly in the field of Light curve, limiting it down to concerns involving Hypernova and, occasionally, GRB 970228.
His research investigates the connection between Astronomy and topics such as Gamma ray that intersect with problems in Flux. Jochen Greiner interconnects Extinction, Metallicity and Spectral energy distribution in the investigation of issues within Gamma-ray burst. The study incorporates disciplines such as Spectroscopy, Quasar, Emission spectrum and Blazar in addition to Redshift.
