The outer rings of SN 1987A from year 1994 to 2024: morphology, light curves, and optical to mid-infrared spectra
Sophie Rosu, Elko Gerville-Reache, Steven Thomas +14
The outer rings (ORs) of Supernova (SN) 1987A were ejected ~20000 years before the explosion. Their characterisation is crucial for constraining the properties of the progenitor of…
Exploring the central region of SNR 0540-69.3 with JWST I: 3D morphology
J. Larsson, C. Tegkelidis, C. Fransson +3
The young supernova remnant SNR 0540-69.3 in the Large Magellanic Cloud offers a detailed view of an energetic pulsar-wind nebula interacting with the surrounding ejecta. We presen…
No rungs attached: A distance-ladder free determination of the Hubble constant through type II supernova spectral modelling
Christian Vogl, Stefan Taubenberger, Géza Csörnyei +10
The ongoing discrepancy in the Hubble constant () estimates obtained through local distance ladder methods and early universe observations poses a significant challenge to the…
Forbidden lines are not quenched
