Solar-System Abundances of -Nuclides Probe Collective Neutrino Oscillations in Supernovae
Alexander Friedland, Derek J. Li, Giuseppe Lucente +3
Direct evidence for collective neutrino oscillations in core-collapse supernovae remains elusive. We show that this quantum phenomenon leaves a footprint on the abundance pattern o…
Successful -process in neutrino-driven outflows in core-collapse supernovae
Alexander Friedland, Payel Mukhopadhyay, Amol V. Patwardhan
The origin of the solar system abundances of several proton-rich isotopes, especially Mo and Ru, has been an enduring mystery in nuclear astrophysics. An attrac…
A Hierarchical Framework for explaining the Cosmic Ray Spectrum using Diffusive Shock Acceleration
Roger Blandford, Paul Simeon, Noémie Globus +3
The hypothesis that the entire cosmic ray spectrum, from to energy, can be accounted for by diffusive shock acceleration on increasin…
Reacceleration of Galactic Cosmic Rays Beyond the Knee at the Termination Shock of a Cosmic-Ray-Driven Galactic Wind
Payel Mukhopadhyay, Enrico Peretti, Noemie Globus +2
The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube w…
Self-Generated Cosmic-Ray Turbulence Can Explain the Morphology of TeV Halos
Payel Mukhopadhyay, Tim Linden
Observations have shown that spatially extended "TeV halos" are a common (and potentially generic) feature surrounding young and middle-aged pulsars. However, their morphology is n…
Celestial-Body Focused Dark Matter Annihilation Throughout the Galaxy
Rebecca K. Leane, Tim Linden, Payel Mukhopadhyay +1
Indirect detection experiments typically measure the flux of annihilating dark matter (DM) particles propagating freely through galactic halos. We consider a new scenario where cel…
Near-critical supernova outflows and their neutrino signatures
Alexander Friedland, Payel Mukhopadhyay
We demonstrate that the neutrino-driven outflows inside exploding core-collapse supernovae possess a special property of near-criticality, that is, they are on the edge of forming…
Carter Constant and Superintegrability
Payel Mukhopadhyay, Rajesh Kumble Nayak
Carter constant is a non-trivial conserved quantity of motion of a particle moving in stationary axisymmetric spacetime. In the version of the theorem originally given by Carter, d…
Quark stars admixed with dark matter
Payel Mukhopadhyay, Juregen Schaffner-Bielich
Compact stars consisting of massless quark matter and fermionic dark matter are studied by solving the Tolman-Oppenheimer-Volkoff equations for two fluids separately. Dark matter i…
