The Nucleosynthetic Yields of Core-collapse Supernovae: Prospects for the Next Generation of Gamma-Ray Astronomy [PDF]
Astrophysical Journal, 2019 Though the neutrino-driven convection model for the core-collapse explosion mechanism has received strong support in recent years, there are still many uncertainties in the explosion parameters—such as explosion energy, remnant mass, and end-of-life ...

Advanced Compton Telescope Designs and SN Science [PDF]
, 2001 The Advanced Compton Telescope (ACT) has been suggested to be the optimal next-generation instrument to study nuclear gamma-ray lines. In this work, we investigate the potential of three hypothetical designs of the ACT to perform SN science.

Revision of the γ-Ray Emission from SNR CTB 109 with the Fermi Large Area Telescope
The Astrophysical Journal, 2023 CTB 109 is a middle-aged shell-type supernova remnant (SNR) with bright thermal X-ray emission. We reanalyze the GeV γ -ray emission from CTB 109 using 13 yr of Pass 8 data recorded by the Fermi Large Area Telescope.

Gamma ray astronomy above 30 TeV and the IceCube results
EPJ Web of Conferences, 2017 The study of the diffuse Galactic gamma ray emission is of fundamental importance to understand the properties of cosmic ray propagation in the Milky Way, and extending the measurements to E ≳ 30 TeV is of great interest.
