Quasi-periodic oscillations during magnetar giant flares in the strangeon star model

Kavli Affiliate: Lijing Shao | First 5 Authors: Hong-Bo Li, Yacheng Kang, Zexin Hu, Lijing Shao, Cheng-Jun Xia | Summary: Soft gamma-ray repeaters (SGRs) are widely understood as slowly rotating isolated neutron stars. Their generally large spin-down rates, high magnetic fields, and strong outburst energies render them different from ordinary pulsars. In a few giant […]

Axion detection via superfluid $^3$He ferromagnetic phase and quantum measurement techniques

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: So Chigusa, Dan Kondo, Hitoshi Murayama, Risshin Okabe, Hiroyuki Sudo | Summary: We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid $^3$He for the axion dark matter detection. This approach is striking in that it is sensitive to the axion-nucleon […]

A Hierarchical Framework for explaining the Cosmic Ray Spectrum using Diffusive Shock Acceleration

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Paul Simeon, NoĆ©mie Globus, Payel Mukhopadhyay, Enrico Peretti | Summary: The hypothesis that the entire cosmic ray spectrum, from $lesssim1,{rm GeV}$ to $gtrsim100,{rm EeV}$ energy, can be accounted for by diffusive shock acceleration on increasingly large scales is critically examined. Specifically, it is conjectured that […]

Optimal Photodetector Size for High-Speed Free-Space Optics Receivers

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Muhammad Salman Bashir, Qasim Zeeshan Ahmed, Mohamed-Slim Alouini, , | Summary: The selection of an optimal photodetector area is closely linked to the attainment of higher data rates in optical wireless communication receivers. If the photodetector area is too large, the channel capacity degrades due to lower […]

Taking the Milky Way for a spin: disc formation in the ARTEMIS simulations

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Adam M. Dillamore, Vasily Belokurov, Andrey Kravtsov, Andreea S. Font, | Summary: We investigate the formation (spin-up) of galactic discs in the ARTEMIS simulations of Milky Way-mass galaxies. In almost all galaxies discs spin up at higher [Fe/H] than the Milky Way (MW). Those that contain an […]
