Kavli Affiliate: T. Higuchi | First 5 Authors: T. Oshio, R. Nishimoto, T. Higuchi, K. Hayasaka, K. Koike | Summary: The quantum charge-coupled device (QCCD) is one of the notable architectures to achieve large-scale trapped-ion quantum computers. To realize QCCD architecture, ions must be transported quickly while minimizing motional excitation. High-voltage sources are necessary to […]

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kimihiko Nakajima, Masami Ouchi, Yuki Isobe, Yi Xu, Shinobu Ozaki | Summary: Using the Subaru/FOCAS IFU capability, we examine the spatially resolved relationships between gas-phase metallicity, stellar mass, and star-formation rate surface densities (Sigma_* and Sigma_SFR, respectively) in extremely metal-poor galaxies (EMPGs) in the local universe. Our […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sarah Healy, Shunsaku Horiuchi, Chris Ashall, , | Summary: The red supergiant (RSG) problem, which describes the apparent lack of high-luminosity progenitors detected in Type II supernova (SN) pre-images, has been a contentious topic for two decades. We re-assess this problem using a new RSG population of […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Motoko Fujiwara, Gonzalo Herrera, Shunsaku Horiuchi, , | Summary: Multi-messenger observations of astrophysical transients provide powerful probes of the underlying physics of the source as well as beyond the Standard Model effects. We explore transients that can occur in the vicinity of supermassive black holes at the […]

Kavli Affiliate: Jia Liu | First 5 Authors: Yuchen Ling, Shengcheng Yu, Chunrong Fang, Guobin Pan, Jun Wang | Summary: Context: Crowdsourced testing has gained popularity in software testing, especially for mobile app testing, due to its ability to bring diversity and tackle fragmentation issues. However, the openness of crowdsourced testing presents challenges, particularly in […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Gregory Gabadadze, David N. Spergel, Giorgi Tukhashvili, , | Summary: We study inflation in a recently proposed gravitational effective field theory describing the trace anomaly. The theory requires an additional scalar which is massless in the early universe. This scalar — referenced as an anomalyon — […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report measurements of the absolute branching fractions $mathcal{B}(B_s^0 to D_s^{pm} X)$, $mathcal{B}(B_s^0 to D^0/bar{D}^0 X)$, and $mathcal{B}(B_s^0 to D^{pm} X)$, where the latter is measured for the first time. The results are based on a […]

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Shunsuke Neda, Satoshi Shirai, | Summary: Recent observations by pulsar timing arrays (PTAs) indicate a potential detection of a stochastic gravitational wave (GW) background. Metastable cosmic strings have been recognized as a possible source of the observed signals. In this paper, we propose […]
