Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Ronny Frumkin, Yonit Hochberg, Eric Kuflik, Hitoshi Murayama, | Summary: We propose a new thermal dark matter candidate whose abundance is determined by the freezeout of inverse decays. The relic abundance depends parametrically only on a decay width, while matching the observed value requires that the coupling […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: A. Schillaci, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: The BICEP/Keck Collaboration is currently leading the quest to the highest sensitivity measurements of the polarized CMB anisotropies on degree scale with a series of cryogenic telescopes, of which BICEP Array is […]
Kavli Affiliate: Kent D. Irwin | First 5 Authors: Marion Dierickx, P. A. R. Ade, Zeeshan Ahmed, Mandana Amiri, Denis Barkats | Summary: The BICEP/Keck series of experiments target the Cosmic Microwave Background at degree-scale resolution from the South Pole. Over the next few years, the "Stage-3" BICEP Array (BA) telescope will improve the program’s […]

Kavli Affiliate: Brian Nord | First 5 Authors: Michelle Ntampaka, Matthew Ho, Brian Nord, , | Summary: Astronomy is entering an era of data-driven discovery, due in part to modern machine learning (ML) techniques enabling powerful new ways to interpret observations. This shift in our scientific approach requires us to consider whether we can trust […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Koji Ishiwata, Eiichiro Komatsu, Ippei Obata, , | Summary: Phenomenological success of inflation models with axion and SU(2) gauge fields relies crucially on control of backreaction from particle production. Most of the previous study only demanded the backreaction terms in equations of motion for axion and gauge […]
Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Yevgeny V. Stadnik, , , , | Summary: In the recent work [Dailey et al., Nature Astronomy 5, 150 (2021)], it was claimed that networks of quantum sensors can be used as sensitive multi-messenger probes of astrophysical phenomena that produce intense bursts of relativistic bosonic waves […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, KICP/UChicago, The Kavli Foundation, , | Summary: Big-bang nucleosynthesis (BBN), a pillar of modern cosmology, begins with the trailblazing 1948 paper of Alpher, Bethe and Gamow cite{abc} which proposed nucleosynthesis during an early ($t sim 1 – 1000,$sec), radiation-dominated phase of the Universe […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, KICP/UChicago, The Kavli Foundation, , | Summary: Big-bang nucleosynthesis (BBN), today a pillar of modern cosmology, began with the trailblazing 1948 paper of Alpher, Bethe and Gamow. In it, they proposed non-equilibrium nuclear processes in the early Universe ($t sim 1000,$sec) and an […]
