Deciphering the Remnants of Core-Collapse Supernovae: Reconstructing Progenitor Star Properties and Explosion Mechanisms
Salvatore Orlando
(Abridged) Recent JWST observations of Cassiopeia A (Cas A) reveal unprecedented ejecta substructure, including a web of filaments and the enigmatic "Green Monster" (GM), character…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Predicting the X-ray signatures of the imminent T Coronae Borealis outburst through 3D hydrodynamic modeling
S. Orlando, L. Chomiuk, J. Drake +3
T Coronae Borealis (T CrB) is a symbiotic recurrent nova with eruptions in 1866 and 1946. Mounting evidence suggests an imminent outburst, offering a rare opportunity to observe a…
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…
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…
Filamentary Ejecta Network in Cassiopeia~A Reveals Fingerprints of the Supernova Explosion Mechanism
S. Orlando, H. -T. Janka, A. Wongwathanarat +7
[Abridged] Recent JWST observations have revealed an intricate filamentary network of unshocked ejecta in the young supernova remnant (SNR) Cassiopeia A (Cas A), offering new insig…
