Insights into the Production of 44Ti and Nickel Isotopes in Core-collapse Supernovae

The Astrophysical Journal
We report nucleosynthetic results for both ^44 Ti and nickel isotopes for 18 three-dimensional (3D) core-collapse supernova (CCSN) simulations extended to ∼20 s after bounce.

Constraining the Pulsar 3D Velocity Distribution: The Impact of Spin–Velocity Alignment

The Astrophysical Journal
Quantifying the natal kick distribution of pulsars is essential for understanding supernova physics and binary evolution, yet measurements are historically limited by the lack of radial velocity data.

SN 2021foa: The “Flip-flop” Type IIn/Ibn Supernova

The Astrophysical Journal
We present a comprehensive analysis of the photometric and spectroscopic evolution of SN 2021foa, unique among the class of transitional supernovae for repeatedly changing its spectroscopic appearance from hydrogen-to-helium-to-hydrogen dominated (IIn-to-

Neutrinos from core-collapse supernovae

The core of a massive star (M > 8 Msun) eventually collapses. This implosion usually triggers a supernova (SN) explosion that ejects most of the stellar envelope and leaves behind a neutron star (NS) with a mass of up to about 2 Msun. Sometimes the explosion fails and a black hole forms instead.

A Comparative Study of the Supernova Remnant Cassiopeia A from 2013 to 2020 Deep [Fe ii] + [Si i] Images

The Astrophysical Journal
We present a comparative analysis of supernova remnant Cassiopeia A based on two deep, narrow-band images covering the [Fe ii ] 1.644 μ m + [Si i ] 1.645 μ m lines obtained in 2013 and 2020 with the same instruments on the UKIRT 3.8 m telescope.
