Kavli Affiliate: T. Higuchi | First 5 Authors: F. Abudinén, I. Adachi, R. Adak, K. Adamczyk, L. Aggarwal | Summary: This paper reports a study of $B to K^{*}gamma$ decays using $62.8pm 0.6$ fb$^{-1}$ of data collected during 2019–2020 by the Belle II experiment at the SuperKEKB $e^{+}e^{-}$ asymmetric-energy collider, corresponding to $(68.2 pm 0.8) […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Takayuki Toda, Yuki Sakurai, Hirokazu Ishino, Tomotake Matsumura, Kunimoto Komatsu | Summary: The polarization modulator unit for the low-frequency telescope in LiteBIRD employs an achromatic half-wave plate (AHWP). It consists of five layers of a-cut sapphire plate, which are stacked based on a Pancharatnam recipe. In this […]
Kavli Affiliate: Rebecca Masterson | First 5 Authors: Jaesub Hong, Richard P. Binzel, Branden Allen, David Guevel, Jonathan Grindlay | Summary: The REgolith X-ray Imaging Spectrometer (REXIS) instrument on board NASA’s OSIRIS-REx mission to the asteroid Bennu is a Class-D student collaboration experiment designed to detect fluoresced X-rays from the asteroid’s surface to measure elemental […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S Bennett, Debora Sijacki, , , | Summary: The use of galaxy clusters as cosmological probes often relies on understanding the properties and evolution of the intracluster medium (ICM). However, the ICM is a complex plasma, regularly stirred by mergers and feedback, with non-negligible bulk and […]

Kavli Affiliate: Albert Stebbins | First 5 Authors: Christina Gao, Albert Stebbins, , , | Summary: In this paper we study how a Yukawa coupling of the Standard Model fermions to a light scalar field effects the stellar structure of cold stellar remnants such as neutron stars. We elucidate the stellar structure phenomenology using a […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada, Hironao Miyatake, | Summary: We present the results obtained from the full-shape cosmology analysis of the redshift-space power spectra for 4 galaxy samples of the SDSS-III BOSS DR12 galaxy catalog over $0.2 < z < 0.75$. For the theoretical template, we […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Ting S. Li, Alexander P. Ji, Andrew B. Pace, Denis Erkal, Sergey E. Koposov | Summary: We report the kinematic, orbital, and chemical properties of 12 stellar streams with no evident progenitors, using line-of-sight velocities and metallicities from the Southern Stellar Stream Spectroscopic Survey ($S^5$), proper […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Nicholas Scarsdale, Joseph M. Akana Murphy, Natalie M. Batalha, Ian J. M. Crossfield, Courtney D. Dressing | Summary: We present the discovery of two nearly identically-sized sub-Neptune transiting planets orbiting HD 63935, a bright ($V=8.6$ mag), sun-like ($T_{eff}=5560K$) star at 49 pc. TESS identified the first planet, […]
