We propose a future mission concept, the MeV Astrophysical Spectroscopic Surveyor (MASS), which is a large area Compton telescope using 3D position sensitive cadmium zinc telluride…
Thallium-208: a beacon of in situ neutron capture nucleosynthesis
Nicole Vassh, Xilu Wang, Maude Lariviere +7
We demonstrate that the well-known 2.6 MeV gamma-ray emission line from thallium-208 could serve as a real-time indicator of astrophysical heavy element production, with both rapid…
Collective neutrino oscillations and heavy-element nucleosynthesis in supernovae: exploring potential effects of many-body neutrino correlations
A. Baha Balantekin, Michael J. Cervia, Amol V. Patwardhan +2
In high-energy astrophysical processes involving compact objects, such as core-collapse supernovae or binary neutron star mergers, neutrinos play an important role in the synthesis…
Could a Kilonova Kill: a Threat Assessment
Haille M. L. Perkins, John Ellis, Brian D. Fields +5
Binary neutron star mergers (BNS) produce high-energy emissions from several physically different sources, including a gamma-ray burst (GRB) and its afterglow, a kilonova, and, at…
Observation of GRB 221009A early afterglow in X/-ray energy band
Chao Zheng, Yan-Qiu Zhang, Shao-Lin Xiong +45
The early afterglow of a Gamma-ray burst (GRB) can provide critical information on the jet and progenitor of the GRB. The extreme brightness of GRB 221009A allows us to probe its e…
