Improved Polarization Calibration of the BICEP3 CMB Polarimeter at the South Pole

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: J. Cornelison, C. Vergès, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: The BICEP3 Polarimeter is a small aperture, refracting telescope, dedicated to the observation of the Cosmic Microwave Background (CMB) at 95GHz. It is designed to target degree angular scale polarization patterns, in particular […]

Polarizations of Gravitational Waves in the Bumblebee Gravity Model

Kavli Affiliate: Lijing Shao | First 5 Authors: Dicong Liang, Rui Xu, Xuchen Lu, Lijing Shao, | Summary: Lorentz violation modifies the dispersion relation of gravitational waves (GWs), and induces birefringence and anisotropy in propagation. Our study shows that Lorentz violation can also activate multiple polarizations of GWs. We use the gauge invariants to investigate […]

First Insights into the ISM at $z>8$ with JWST: Possible Physical Implications of a High [O III]$mathbf{λ4363}$/[O III]$mathbf{λ 5007}$

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Harley Katz, Aayush Saxena, Alex J. Cameron, Stefano Carniani, Andrew J. Bunker | Summary: We present a detailed analysis of the rest-frame optical emission line ratios for three spectroscopically confirmed galaxies at $z>7.5$. The galaxies were identified in the James Webb Space Telescope (JWST) Early Release Observations […]

Diagnosing FUor-like Sources: The Parameter Space of Viscously Heated Disks in the Optical and Near-IR

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Hanpu Liu, Gregory J. Herczeg, Doug Johnstone, Carlos Contreras-Peña, Jeong-Eun Lee | Summary: FU Ori type objects (FUors) are decades-long outbursts of accretion onto young stars that are strong enough to viscously heat disks so that the disk outshines the central star. We construct models for […]
