Please join us for an open lecture by dr. Takashi Moriya (National Observatory of Japan) entitled “Supernova properties across cosmic history”, prepared as part of the mentoring visit under Action I.1.1/IV.1.1 “Mentoring Programme”.

Supernovae play essential roles in cosmic history. They provide metals and energies to the surroundings, driving the chemical and dynamical evolution of the Universe. Among various types of supernovae, core-collapse supernovae from massive stars start to appear shortly after the formation of the first stars in the primordial Universe. Thus, understanding their properties throughout cosmic history is essential to uncover the evolution of the Universe. In this talk, I will first discuss general properties of core-collapse supernovae in the local Universe that are revealed by extensive optical transient surveys in the last decade. Then, I will introduce the recent discoveries of high-redshift core-collapse supernovae at high redshifts by JWST. I will discuss possible differences among nearby and high-redshift core-collapse supernova properties based on them.

Dr Takashi Moriya is an Assistant Professor at National Astronomical Observatory of Japan. He is also hired as an Adjunct Research Fellow at Monash University, Australia. His researches are focused on the evolution of massive stars and explosion mechanisms of core collapse supernovae. Despite his youth, he is a well-regarded expert in supernova theory and frequently gives invited talks and serves on scientific organizing committees for various conferences in this area. Additionally, he leads transient working groups for the Euclid and Roman space missions and has a similar role within the Japanese Subaru telescope community.

The lecture will take place on Tuesday, 3 June 2025 at 16:00 in the Copernicus Lecture Hall, located on the second floor of the Astronomical Observatory of the University of Warsaw, al. Ujazdowskie 4.
