Explosion Mechanisms of Core-Collapse Supernovae [PDF]

Annual Review of Nuclear and Particle Science, 2012
Supernova theory, numerical and analytic, has made remarkable progress in the past decade. This progress was made possible by more sophisticated simulation tools, especially for neutrino transport, improved microphysics, and deeper insights into the role

Revealing the Progenitor of SN 2021zby through Analysis of the TESS Shock-cooling Light Curve

The Astrophysical Journal Letters, 2023
We present early observations and analysis of the double-peaked Type IIb supernova (SN IIb) SN 2021zby. TESS captured the prominent early shock-cooling peak of SN 2021zby within the first ∼10 days after explosion with a 30 minute cadence.

Prospects for Extending the Core-collapse Supernova Detection Horizon Using High-energy Neutrinos

The Astrophysical Journal, 2023
Large neutrino detectors like IceCube monitor for core-collapse supernovae using low-energy (MeV) neutrinos with a detection reach from a supernova neutrino burst to the Magellanic Cloud. However, some models predict the emission of high-energy neutrinos

Early Hard X-Rays from the Nearby Core-collapse Supernova SN 2023ixf

The Astrophysical Journal Letters, 2023
We present NuSTAR observations of the nearby SN 2023ixf in M101 ( d = 6.9 Mpc) that provide the earliest hard X-ray detection of a nonrelativistic stellar explosion to date at δ t ≈ 4 days and δ t ≈ 11 days.

The Type II-P Supernova 2019mhm and Constraints on its Progenitor System

The Astrophysical Journal, 2023
We present pre- and postexplosion observations of the Type II-P supernova (SN II-P) 2019mhm located in NGC 6753. Based on optical spectroscopy and photometry, we show that SN 2019mhm exhibits broad lines of hydrogen with a velocity of −8500 ± 200 km s ...

Black Hole Formation Accompanied by the Supernova Explosion of a 40 M ⊙ Progenitor Star

The Astrophysical Journal, 2023
We have simulated the collapse and evolution of the core of a solar-metallicity 40 M _⊙ star and find that it explodes vigorously by the neutrino mechanism, despite its very high “compactness.” Within ∼1.5 s of explosion, a black hole forms.

Constraining High-energy Neutrino Emission from Supernovae with IceCube

The Astrophysical Journal Letters, 2023
Core-collapse supernovae are a promising potential high-energy neutrino source class. We test for correlation between seven years of IceCube neutrino data and a catalog containing more than 1000 core-collapse supernovae of types IIn and IIP and a sample ...

The First Two Years of FLEET: An Active Search for Superluminous Supernovae

The Astrophysical Journal, 2023
In 2019 November, we began operating Finding Luminous and Exotic Extragalactic Transients (FLEET), a machine-learning algorithm designed to photometrically identify Type I superluminous supernovae (SLSNe) in transient alert streams.

Neutrinos from core-collapse supernovae at KM3NeT [PDF]

EPJ Web of Conferences, 2023
The SN1987A supernova was the first extragalactic neutrino de- tection, but no further observations have been made since. Detecting neutrinos from a galactic supernova would provide invaluable information on the supernova mechanism and particle behavior ...

Possible Detection of the Progenitor of the Type II Supernova SN 2023ixf

The Astrophysical Journal Letters, 2023
Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae. Locating and characterizing the progenitors of well-studied supernovae is important to constrain the theory and to justify and design future surveys to ...
