Axion-Gauge Field Dynamics with Backreaction

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 […]

Comment on ”Quantum sensor networks as exotic field telescopes for multi-messenger astronomy”

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 […]

Predicting the CMB temperature

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 […]

Understanding BBN: the physics and its history

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 […]

The physics of Lyman-alpha escape from disc-like galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aaron Smith, Rahul Kannan, Sandro Tacchella, Mark Vogelsberger, Lars Hernquist | Summary: Hydrogen emission lines can provide extensive information about star-forming galaxies in both the local and high-redshift Universe. We present a detailed Lyman continuum (LyC), Lyman-alpha (Ly{alpha}), and Balmer line (H{alpha} and Hb{eta}) radiative transfer study […]

Sources of systematic error in gravitational-wave measurements of the binary neutron star mass distribution

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Colm Talbot, Salvatore Vitale, , | Summary: The binary neutron star (BNS) mass distribution measured with gravitational-wave observations has the potential to reveal information about the dense matter equation of state, supernova physics, the expansion rate of the universe, and tests of General Relativity. As […]

Detection of a Parsec-Scale Jet in a Radio-Quiet Narrow-Line Seyfert 1 Galaxy with Highly Accreting Supermassive Black Hole

Kavli Affiliate: Ran Wang | First 5 Authors: Su Yao, Xiaolong Yang, Minfeng Gu, Tao An, Jun Yang | Summary: The jet in active galactic nuclei (AGN) is a key ingredient in understanding the co-evolution of galaxies and their central supermassive black holes (SMBHs). Unfortunately, the mechanism of jet launching and collimation is still elusive. […]
