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…

The evolution of the mid-infrared spectrum of SN 1987A observed with the JWST/MIRI-MRS

P. J. Kavanagh, M. J. Barlow, C. Fransson +19

Supernova (SN) 1987A provides a unique laboratory for investigating many aspects of SN physics and evolution. An observation at Day 12927 (35.4 yr) since the explosion with the Mid…

MUSE Observations Reveal Optical Coronal Iron Lines from Shock Emission in Supernova Remnant 0540-69.3

L. Tenhu, J. Larsson, P. Lundqvist +3

We investigate the optical shock emission from the Large Magellanic Cloud supernova remnant 0540-69.3 (SNR 0540) using MUSE integral-field-unit data from the VLT. The observations…

The compact object and innermost ejecta of SN 1987A

J. Larsson, C. Fransson, P. J. Kavanagh +12

The first JWST observations of SN 1987A provided clear evidence that a compact object is ionizing the innermost ejecta. Here we analyze a second epoch of JWST NIRSpec and MIRI/MRS…

Tracing the Propagation of Shocks in the Equatorial Ring of SN 1987A Over Decades with the Hubble Space Telescope

Christos Tegkelidis, Josefin Larsson, Claes Fransson

The nearby SN 1987A offers a unique opportunity to investigate the complex shock interaction between the ejecta and circumstellar medium. We track the evolution of the optical hots…

Hubble Space Telescope images of SN 1987A: Evolution of the ejecta and the equatorial ring from 2009 to 2022

Sophie Rosu, Josefin Larsson, Claes Fransson +9

Supernova (SN) 1987A offers a unique opportunity to study how a spatially resolved SN evolves into a young supernova remnant (SNR). We present and analyze Hubble Space Telescope (H…
