Testing a Pre-Supernova Contribution to Ti in Cassiopeia A

Toshiki Sato, Joshua Issa, Falk Herwig +4

The radioactive isotope Ti in Cassiopeia A has been used as a tracer of the innermost ejecta and explosion asymmetries in core-collapse supernova explosions. However, recent…

Cosmic Ray Electron Evolution in Supernova Remnants: Log-Parabola Distribution

Joshua J. Ziegler, Justin D. Finke, J. Martin Laming

The shock fronts of supernova remnants (SNRs) are believed to be significant sites of acceleration of cosmic ray particles. Previous researchers have shown that a particle distribu…

The Green Monster hiding in front of Cas A: JWST reveals a dense and dusty circumstellar structure pockmarked by ejecta interactions

Ilse De Looze, Dan Milisavljevic, Tea Temim +27

JWST observations of the young Galactic supernova remnant Cassiopeia A revealed an unexpected structure seen as a green emission feature in colored composite MIRI F1130W and F1280W…

Dissecting the Crab Nebula with JWST: Pulsar wind, dusty filaments, and Ni/Fe abundance constraints on the explosion mechanism

Tea Temim, J. Martin Laming, P. J. Kavanagh +19

We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics, plus MIRI/MRS IFU spectra t…

A JWST Survey of the Supernova Remnant Cassiopeia A

Dan Milisavljevic, Tea Temim, Ilse De Looze +43

We present initial results from a JWST survey of the youngest Galactic core-collapse supernova remnant Cassiopeia A (Cas A), made up of NIRCam and MIRI imaging mosaics that map emi…

Element Abundances in the Unshocked Ejecta of Cassiopeia A

J. Martin Laming, Tea Temim

We analyze and model the infrared spectrum of the Cassiopeia A supernova remnant, with the aim of determining the masses of various elements in the unshocked ejecta. In this way we…
