Conferències al DAA. Xarrada a càrrec de l'investigador Alexei Tolstov, del Kavli IPMU, Univ. de Tokio (Japó). Lloc: Seminari del Departament d'Astronomia i Astrofísica, 4a planta de l'Edifici d'Investigació, a Burjassot. Dia: divendres 26 de febrer de 2018. Hora: 12:00.

RESUM:

Observations of Gaia16apd revealed extremely luminous ultraviolet (UV) emission among superluminous supernovae (SLSNe). I will present the results of comparison of UV light curves, color temperatures, and photospheric velocities in radiation hydrodynamics simulations between the most popular SLSN models: pair-instability supernova, magnetar, and interaction with circumstellar medium. Observations at UV wavelengths can be used to clarify the nature of SLSNe and more attention should be paid to them in future follow-up observations.
