Quasithermal GeV neutrinos from neutron-loaded magnetized outflows in core-collapse supernovae: spectra and light curves

Posted by dbos Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Jose Alonso Carpio, Nick Ekanger, Mukul Bhattacharya, Kohta Murase, Shunsaku Horiuchi | Summary: Rapidly rotating and strongly magnetized protoneutron stars (PNSs) created in core-collapse supernovae can drive relativistic magnetized winds. Ions and neutrons can be co-accelerated while they remain coupled through elastic collisions. We investigate the nucleosynthesis […]

Probing extreme black-hole outflows on short timescales via high spectral-resolution X-ray imagers

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ciro Pinto, James F. Steiner, Arash Bodaghee, Priyanka Chakraborty, Malgosia Sobolewska | Summary: We investigate outflows and the physics of super-Eddington versus sub-Eddington regimes in black hole systems. Our focus is on prospective science using next-generation high-resolution soft X-ray instruments. We highlight the properties of black hole […]

A roadmap to the efficient and robust characterization of temperate terrestrial planet atmospheres with JWST

Posted by dbos MIT

Kavli Affiliate: Sara Seager | First 5 Authors: TRAPPIST-1 JWST Community Initiative, :, Julien de Wit, René Doyon, Benjamin V. Rackham | Summary: Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominent is the M8.5V star TRAPPIST-1 and its […]

Constraining exotic dark matter models with the dark ages 21-cm signal

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Rajesh Mondal, Rennan Barkana, Anastasia Fialkov, , | Summary: The 21-cm signal from the dark ages is a powerful tool for fundamental cosmology and for probing new physics. While it can be used for precision measurements within standard cosmology, here we study two non-standard models: an excess […]
