Origin of holes and rings in the Green Monster of Cassiopeia A: Insights from 3D magnetohydrodynamic simulations

S. Orlando, H. -T. Janka, A. Wongwathanarat +10

[Abridged] Cassiopeia A (Cas A) provides a unique opportunity to study supernova (SN) dynamics and interactions with the circumstellar medium (CSM). Recent JWST observations reveal…

Modeling particle acceleration and non-thermal emission in supernova remnants

S. Orlando, M. Miceli, S. Ustamujic +5

According to the most popular model for the origin of cosmic rays (CRs), supernova remnants (SNRs) are the site where CRs are accelerated. Observations across the electromagnetic s…

Tracing the ejecta structure of SN 1987A: Insights and diagnostics from 3D MHD simulations

S. Orlando, M. Miceli, M. Ono +14

Supernova (SN) 1987A provides a unique window into the aftermath of a massive stellar explosion, offering key insights into the ejecta's morphology, composition, explosion mechanis…

Modeling the mixed-morphology supernova remnant IC 443. Origin of its complex morphology and X-ray emission

S. Ustamujic, S. Orlando, E. Greco +4

The morphology and the distribution of material observed in SNRs reflect the interaction of the SN blast wave with the ambient environment, the physical processes associated with t…

Constraining the CSM structure and progenitor mass-loss history of interacting supernovae through 3D hydrodynamic modeling: The case of SN 2014C

S. Orlando, E. Greco, R. Hirai +9

We investigate SN 2014C using three-dimensional hydrodynamic modeling, focusing on its early interaction with dense circumstellar medium (CSM). Our objective is to uncover the pre-…

Evidence for thermal X-ray emission from the synchrotron dominated shocks in Tycho's supernova remnant

A. Ellien, E. Greco, J. Vink

Young supernova remnants (SNRs) shocks are believed to be the main sites of galactic cosmic rays production, showing X-ray synchrotron dominated spectra in the vicinity of their sh…

Negative and Positive Feedback from a Supernova Remnant with SHREC: A detailed Study of the Shocked Gas in IC443

G. Cosentino, I. Jiménez-Serra, J. C. Tan +20

Supernova remnants (SNRs) contribute to regulate the star formation efficiency and evolution of galaxies. As they expand into the interstellar medium (ISM), they transfer vast amou…
