Kavli Affiliate: Edward Kolb | First 5 Authors: Daniel Carney, Nirmal Raj, Yang Bai, Joshua Berger, Carlos Blanco | Summary: We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly $10~{rm TeV}$ and the Planck scale $m_{rm pl} approx 10^{16}~{rm TeV}$. This mass range presents a […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Emanuele Berti, Vitor Cardoso, Zoltán Haiman, Daniel E. Holz, Emil Mottola | Summary: Gravitational wave detectors are formidable tools to explore strong-field gravity, especially black holes and neutron stars. These compact objects are extraordinarily efficient at producing electromagnetic and gravitational radiation. As such, they are ideal […]

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: J. A. Bagger, B. C. Barish, S. Belomestnykh, P. C. Bhat, J. E. Brau | Summary: We discuss considerations that can be used to formulate recommendations for initiating a lepton collider project that would provide precision studies of the Higgs boson and related electroweak phenomena. | […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim, Adriano Agnello, Ozgur Akarsu | Summary: In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological probes, such as the […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Hajime Fukuda, Hidetoshi Otono, Satoshi Shirai, , | Summary: One of the most promising methods to search for axions is a light-shining-through-walls (LSW) experiment. In this work, we discuss the possibility of performing an LSW experiment at the ILC experiment, where photon beams are generated for positron […]
Kavli Affiliate: Xian Chen | First 5 Authors: Pau Amaro Seoane, Jeff Andrews, Manuel Arca Sedda, Abbas Askar, Quentin Baghi | Summary: The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many key astrophysical questions in a completely novel […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Neal Dalal, Andrey Kravtsov, , , | Summary: We use observations of ultra-faint dwarf (UFD) galaxies to constrain the particle mass of ultra-light dark matter. Potential fluctuations created by wave interference in virialized "fuzzy" dark matter (FDM) halos dynamically heat stellar orbits in UFDs, some of which […]

Kavli Affiliate: Blake Sherwin | First 5 Authors: The CMB-HD Collaboration, :, Simone Aiola, Yashar Akrami, Kaustuv Basu | Summary: CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep (0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a survey would answer many outstanding questions about the […]
