Inferring Core-Collapse Supernova Physics with Gravitational Waves [PDF]
, 2012 Stellar collapse and the subsequent development of a core-collapse supernova explosion emit bursts of gravitational waves (GWs) that might be detected by the advanced generation of laser interferometer gravitational-wave observatories such as Advanced ...

Search for Axionlike-Particle-Induced Prompt γ-Ray Emission from Extragalactic Core-Collapse Supernovae with the Fermi Large Area Telescope. [PDF]
Physical Review Letters, 2020 During a core-collapse supernova (SN), axionlike particles (ALPs) could be produced through the Primakoff process and subsequently convert into γ rays in the magnetic field of the Milky Way.

Gravitational Waves from Neutrino Emission Asymmetries in Core-collapse Supernovae [PDF]
Astrophysical Journal, 2020 We present a broadband spectrum of gravitational waves (GWs) from core-collapse supernovae (CCSNe) sourced by neutrino emission asymmetries for a series of full 3D simulations.

, 2021 With the localization of fast radio bursts (FRBs) to galaxies similar to the Milky Way and the detection of a bright radio burst from SGR J1935+2154 with energy comparable to extragalactic radio bursts, a magnetar origin for FRBs is evident.

Heavy axion-like particles and core-collapse supernovae: constraints and impact on the explosion mechanism [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Heavy axion-like particles (ALPs), with masses ma ≳ 100 keV, coupled with photons, would be copiously produced in a supernova (SN) core via Primakoff process and photon coalescence.

The Astrophysical Journal, 2023 Previous numerical simulations of double-peaked Type IIb supernova (SN IIb) light curves have demonstrated that the radius and mass of the hydrogen-rich envelope of the progenitor star can significantly influence the brightness and timescale of the early-

The Type Ibn Supernova 2019kbj: Indications for Diversity in Type Ibn Supernova Progenitors
The Astrophysical Journal, 2023 Type Ibn supernovae (SNe) are a rare class of stellar explosions whose progenitor systems are not yet well determined. We present and analyze observations of the Type Ibn SN 2019kbj, and model its light curve in order to constrain its progenitor and ...

Characterizing the Gravitational Wave Signal from Core-collapse Supernovae [PDF]
Astrophysical Journal, 2018 We study the gravitational wave (GW) signal from eight new 3D core-collapse supernova simulations. We show that the signal is dominated by f- and g-mode oscillations of the protoneutron star (PNS) and its frequency evolution encodes the contraction rate ...

Magnetorotational Explosions of Core-Collapse Supernovae
Acta Polytechnica CTU Proceedings, 2014 Core-collapse supernovae are accompanied by formation of neutron stars. The gravitation energy is transformed into the energy of the explosion, observed as SN II, SN Ib,c type supernovae.

The Astrophysical Journal, 2023 The Cassiopeia A supernova remnant has a complex structure, manifesting the multidimensional nature of core-collapse supernova explosions. To further understand this, we carried out near-infrared multiobject spectroscopy on the ejecta knots located in ...
