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

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 […]

Astro 2020: Astromineralogy of interstellar dust with X-ray spectroscopy

Kavli Affiliate: Claude Canizares | First 5 Authors: Lia Corrales, Lynne Valencic, Elisa Costantini, Javier Garcia, Efrain Gatuzz | Summary: X-ray absorption fine structure (XAFS) in the 0.2-2 keV band is a crucial component in multi-wavelength studies of dust mineralogy, size, and shape — parameters that are necessary for interpreting astronomical observations and building physical […]

Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers

Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: Tzu-Ching Chang, Angus Beane, Olivier Dore, Adam Lidz, Lluis Mas-Ribas | Summary: The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a comprehensive understanding of the physics that led to the formation […]

The Dynamic Infrared Sky

Kavli Affiliate: Rob Simcoe | First 5 Authors: Mansi M. Kasliwal, Scott Adams, Igor Andreoni, Michael Ashley, Nadia Blagorodnova | Summary: Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves from neutron star mergers and quantifying the nucleosynthetic yields require the infrared. […]

Cosmology with the Highly Redshifted 21cm Line

Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: Adrian Liu, James Aguirre, Yacine Ali-Haimoud, Marcelo Alvarez, Adam Beardsley | Summary: In addition to being a probe of Cosmic Dawn and Epoch of Reionization astrophysics, the 21cm line at $z>6$ is also a powerful way to constrain cosmology. Its power derives from several unique capabilities. First, […]

Ground motion prediction at gravitational wave observatories using archival seismic data

Kavli Affiliate: Richard Mittleman | First 5 Authors: Nikhil Mukund, Michael Coughlin, Jan Harms, Sebastien Biscans, Jim Warner | Summary: Gravitational wave observatories have always been affected by tele-seismic earthquakes leading to a decrease in duty cycle and coincident observation time. In this analysis, we leverage the power of machine learning algorithms and archival seismic […]
