A statistical study of the environmental age of core-collapse supernovae based on VLT/MUSE integral-field-unit spectroscopy
Qiang Xi, Ning-Chen Sun, Yihan Zhao +13
We aim to understand the progenitor channels of CCSNe via a statistical study of the ages of their environments. We compiled a large and minimally biased sample of 128 CCSNe discov…
The dependence of triggering mechanisms on radio AGN sub-types: the role of galaxy mergers
Freya Barwell, Clive N. Tadhunter, Jonathon C. S. Pierce +10
Powerful, radio-loud active galactic nuclei (AGN) are associated with one of the most important forms of AGN feedback, and understanding how they are triggered is key to properly i…
A statistical study of the metallicity of core-collapse supernovae based on VLT/MUSE integral-field-unit spectroscopy
Qiang Xi, Ning-Chen Sun, Yi-Han Zhao +4
Metallicity plays a crucial role in the evolution of massive stars and their final core-collapse supernova (CCSN) explosions. Integral-field-unit (IFU) spectroscopy can provide a s…
An environmental analysis of supernova iPTF13bvn with HST and MUSE
Adam J. Singleton, Justyn R. Maund, Ning-Chen Sun
Searches for supernovae (SNe) progenitors have relied on a direct detection of the star in fortuitous pre-explosion images. We propose an alternative method, using a combination of…
Signatures of the Shock Interaction as an Additional Power Source in the Nebular Spectra of SN 2023ixf
Amit Kumar, Raya Dastidar, Justyn R. Maund +2
Red supergiants may lose significant mass during the final 100-1000 years before core collapse, shaping their circumstellar environment. The supernova (SN) shockwave propagating th…
