Building Trustworthy Machine Learning Models for Astronomy

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 […]

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 […]

Spectrally Multiplexed Hong-Ou-Mandel Interference

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Oriol Pietx-Casas, Gustavo Castro do Amaral, Tanmoy Chakraborty, Remon Berrevoets, Thomas Middelburg | Summary: We explore the suitability of a Virtually-Imaged Phased Array (VIPA) as a Spectral-to-Spatial Mode-Mapper (SSMM) for applications in quantum communication such as a quantum repeater. To this end we demonstrate spectrally-resolved two-photon "Hong-Ou-Mandel" […]
