Heliosheath Properties Measured from a Voyager 2 to Voyager 1 Transient

Kavli Affiliate: John D. Richardson | First 5 Authors: Jamie S. Rankin, David J. McComas, John D. Richardson, Nathan A. Schwadron, | Summary: In mid-2012, a GMIR observed by Voyager 2 crossed through the heliosheath and collided with the heliopause, generating a pressure pulse that propagated into the very local interstellar medium. The effects of […]

Characterisation of the Particle-Induced Background of XMM-Newton EPIC-pn: Short and Long Term Variability

Kavli Affiliate: Catherine Grant | First 5 Authors: Esra Bulbul, Ralph Kraft, Paul Nulsen, Michael Freyberg, Eric D. Miller | Summary: The particle-induced background of X-ray observatories is produced by Galactic Cosmic Ray (GCR) primary protons, electrons, and He ions. Events due to direct interaction with the detector are usually removed by on board processing. […]

Astro2020 APC White Paper: Providing a Timely Review of Input Demographics to Advisory Committees

Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Dara Norman, Terri J. Brandt, Nancy D. Morrison, Sarah Tuttle, Julie Rathbun | Summary: Organizations that support science (astronomy) such as federal agencies, research centers, observatories, academic institutions, societies, etc. employ advisory committees and boards as a mechanism for reviewing their activities and giving advice on practices, […]

The structure of magnetic turbulence in the heliosheath region observed by Voyager 2 at 106 AU

Kavli Affiliate: John D. Richardson | First 5 Authors: Federico Fraternale, Nikolai V Pogorelov, John D Richardson, Daniela Tordella, | Summary: It is currently believed that the turbulent fluctuations pervade the outermost heliosphere. Turbulence, magnetic reconnection, and their link may be responsible for magnetic energy conversion in these regions. The governing mechanisms of such anisotropic […]

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, […]
