Kavli Affiliate: Troy A. Porter | First 5 Authors: Troy A. Porter, Gudlaugur Johannesson, Igor V. Moskalenko, , | Summary: The past decade has brought impressive advances in astrophysics of cosmic rays (CRs) and multi-wavelength astronomy — thanks to the new instrumentation launched into space and built on the ground. Understanding the astrophysical backgrounds to […]

Kavli Affiliate: Brian Lantz | First 5 Authors: D. H. Shoemaker, Stefan Ballmer, Matteo Barsuglia, E. Berger, Emanuele Berti | Summary: The workshop Dawn VI: Next Generation Observatories}took place online over three days, 5-7 October, 2021. More than 200 physicists and astronomers attended to contribute to, and learn from, a discussion of next-generation ground-based gravitational-wave […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Surjeet Rajendran, , | Summary: A major challenge for gravitational-wave (GW) detection in the $mu$Hz band is engineering a test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept using asteroids located in the inner Solar […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Tony Zhang, Chia-Hsun Chuang, Risa H. Wechsler, Shadab Alam, Joseph DeRose | Summary: Cosmological $N$-body simulations provide numerical predictions of the structure of the universe against which to compare data from ongoing and future surveys. The growing volume of the surveyed universe, however, requires increasingly large […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Nadav Priel, Alexander Fieguth, Charles P. Blakemore, Emmett Hough, Akio Kawasaki | Summary: Optically levitated macroscopic objects are a powerful tool in the field of force sensing, owing to high sensitivity, absolute force calibration, environmental isolation and the advanced degree of control over their dynamics that have […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Ariel Arza, Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia | Summary: We demonstrate that ultralight axion dark matter with a coupling to photons induces an oscillating global terrestrial magnetic field signal in the presence of the background geomagnetic field of the […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Elena Orlando, Eugenio Bottacini, Alexander Moiseev, Arash Bodaghee, Werner Collmar | Summary: The sky at MeV energies is currently poorly explored. Here we present an innovative mission concept and we outline the scientific motivation for combining a coded mask and a Compton telescope. The Galactic Explorer with […]
Kavli Affiliate: Seth Digel | First 5 Authors: Elena Orlando, Eugenio Bottacini, Alexander Moiseev, Arash Bodaghee, Werner Collmar | Summary: The sky at MeV energies is currently poorly explored. Here we present an innovative mission concept that builds on and improves past and currently proposed missions at such energies. We outline the motivations for combining […]
