Magnetic turbulence spectra and intermittency in the heliosheath and in the local interstellar medium

Posted by klaurent MIT

Kavli Affiliate: John D. Richardson | First 5 Authors: Federico Fraternale, Nikolai V Pogorelov, John D Richardson, Daniela Tordella, | Summary: The understanding of inertial-scale dynamics in the heliosheath is not yet thorough. Magnetic field fluctuations across the inner heliosheath (IHS) and the local interstellar medium (LISM) are here considered to provide accurate and highly […]

Reflections On the Anomalous ANITA Events: The Antarctic Subsurface as a Possible Explanation

Posted by klaurent Stanford

Kavli Affiliate: Dustin M. Schroeder | First 5 Authors: Ian M. Shoemaker, Alexander Kusenko, Peter Kuipers Munneke, Andrew Romero-Wolf, Dustin M. Schroeder | Summary: The ANITA balloon experiment was designed to detect radio signals initiated by neutrinos and cosmic ray air showers. These signals are typically discriminated by the polarization and phase inversions of the […]

Astro2020 Science White Paper: Black Holes Across Cosmic Time

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | First 5 Authors: Kayhan Gültekin, Aaron Barth, Karl Gebhardt, Jenny Greene, Luis Ho | Summary: Supermassive black holes are located at the center of most, if not all, massive galaxies. They follow close correlations with global properties of their host galaxies (scaling relations), and are thought to play a crucial […]
