A diffuse scattering model of ultracold neutrons on wavy surfaces

Kavli Affiliate: T. Higuchi | First 5 Authors: S. Imajo, H. Akatsuka, K. Hatanaka, T. Higuchi, G. Ichikawa | Summary: Metal tubes plated with nickel-phosphorus are used in many fundamental physics experiments using ultracold neutrons (UCN) because of their ease of fabrication. These tubes are usually polished to a average roughness of 25-150 nm. However, […]

Constraint on Early Dark Energy from Isotropic Cosmic Birefringence

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Johannes R. Eskilt, Laura Herold, Eiichiro Komatsu, Kai Murai, Toshiya Namikawa | Summary: Polarization of the cosmic microwave background (CMB) is sensitive to new physics violating parity symmetry, such as the presence of a pseudoscalar "axionlike" field. Such a field may be responsible for early dark energy […]

Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS

Kavli Affiliate: Gabor Furesz | First 5 Authors: Angelica Psaridi, François Bouchy, Monika Lendl, Babatunde Akinsanmi, Keivan G. Stassun | Summary: While the sample of confirmed exoplanets continues to increase, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a […]

Hysteresis Compensation in Temperature Response of Fiber Bragg Grating Thermometers Using Dynamic Regression

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeeshan Ahmed, , , , | Summary: In recent years there has been considerable interest in using photonic thermometers such as Fiber Bragg grating (FBG) and silicon ring resonators as an alternative technology to resistance-based legacy thermometers. Although FBG thermometers have been commercially available for decades their […]

Stability and detectability of exomoons orbiting HIP 41378 f, a temperate Jovian planet with an anomalously low apparent density

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Caleb K. Harada, Courtney D. Dressing, Munazza K. Alam, James Kirk, Mercedes Lopez-Morales | Summary: Moons orbiting exoplanets ("exomoons") may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the temperate ($T_text{eq}=294$ K) giant ($R = 9.2$ R$_oplus$) […]
