Plastic Laminate Antireflective Coatings for Millimeter-wave Optics in BICEP Array

Kavli Affiliate: Keith Thompson | 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 frequency coverage and sensitivity to primordial B-mode polarization by an order of magnitude. The first receiver in the […]

Electron Pulse Compression with Optical Beat Note

Kavli Affiliate: Robert L. Byer | First 5 Authors: Zhexin Zhao, Kenneth J. Leedle, Dylan S. Black, Olav Solgaard, Robert L. Byer | Summary: Compressing electron pulses is important in many applications of electron beam systems. In this study, we propose to use optical beat notes to compress electron pulses. The beat frequency is chosen […]

Electron Pulse Compression with Optical Beat Note

Kavli Affiliate: Robert Byer | Summary:Compressing electron pulses is important in many applications of electron beam systems. In this study, we propose to use optical beat notes to compress electron pulses. The beat frequency is chosen to match the initial electron pulse duration, which enables the compression of electron pulses with a wide range of […]

Unveiling the Fermi Bubbles origin with MeV photon telescopes

Kavli Affiliate: Seth Digel | Summary:The Fermi Bubbles (FB) are a pair of large-scale ellipsoidal structures extending above and below the Galactic plane almost symmetrically aligned with the Galactic Center. After more than 10 years since their discovery, their nature and origin remain unclear. Unveiling the primary emission mechanisms, whether hadronic or leptonic, is considered […]

Cosmological Constraints from Gas Mass Fractions of Massive, Relaxed Galaxy Clusters

Kavli Affiliate: Steven Allen, Lindsey E. Bleem, Bradford Benson, Adam B. Mantz | First 5 Authors: Adam B. Mantz, Steven W. Allen, Rebecca E. A. Canning, Lucie Baumont, Bradford Benson | Summary: We present updated cosmological constraints from measurements of the gas mass fractions ($f_{gas}$) of massive, dynamically relaxed galaxy clusters. Our new data set […]

Early-type galaxy density profiles from IllustrisTNG: III. Effects on outer kinematic structure

Kavli Affiliate: Risa Wechsler | First 5 Authors: Yunchong Wang, Shude Mao, Mark Vogelsberger, Volker Springel, Lars Hernquist | Summary: Early-type galaxies (ETGs) possess total radial density profiles that are largely described by singular isothermal spheres, which can lead to non-Gaussian line-of-sight velocity dispersion (LOSVD) under anisotropic stellar orbits. However, recent observations of local ETGs […]

COMAP Early Science: VII. Prospects for CO Intensity Mapping at Reionization

Kavli Affiliate: Sarah E. Church | First 5 Authors: Patrick C. Breysse, Dongwoo T. Chung, Kieran A. Cleary, HÃ¥vard T. Ihle, Hamsa Padmanabhan | Summary: We introduce COMAP-EoR, the next generation of the Carbon Monoxide Mapping Array Project aimed at extending CO intensity mapping to the Epoch of Reionization. COMAP-EoR supplements the existing 30 GHz […]
