Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We report a measurement of the $D^0$ and $D^+$ lifetimes using $D^0to K^-pi^+$ and $D^+to K^-pi^+pi^+$ decays reconstructed in $e^+e^-to cbar{c}$ data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider. […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: C. J. A. P. Martins, Patrick Peter, I. Yu. Rybak, E. P. S. Shellard, | Summary: We apply a recently developed formalism to study the evolution of a current-carrying string network under the simple but generic assumption of a linear equation of state. We demonstrate […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Teruaki Enoto, Mason Ng, Chin-ping Hu, Tolga Guver, Gaurava K. Jaisawal | Summary: The soft gamma-ray repeater Swift J1555.2-5402 was discovered by means of a 12-ms duration short burst detected with Swift BAT on 2021 June 3. Then 1.6 hours after the first burst detection, NICER started […]
Kavli Affiliate: Jia Liu | First 5 Authors: Menglu Yu, Jia Liu, Chuan Wu, Bo Ji, Elizabeth S. Bentley | Summary: Recent years have witnessed a rapid growth of distributed machine learning (ML) frameworks, which exploit the massive parallelism of computing clusters to expedite ML training. However, the proliferation of distributed ML frameworks also introduces […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Nina M. Coyle, Ying-Ying Li, Samuel D. McDermott, Yuhsin Tsai | Summary: Dark matter (DM) with a mass below a few keV must have a phase space distribution that differs substantially from the Standard Model particle thermal phase space: otherwise, it will free stream out […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Ichikawa, Takuji Yamashita, Yoshiki Toba, Tohru Nagao, Kohei Inayoshi | Summary: We present the optical and infrared properties of 39 extremely radio-loud galaxies discovered by cross-matching the Subaru/Hyper Suprime-Cam (HSC) deep optical imaging survey and VLA/FIRST 1.4 GHz radio survey. The recent Subaru/HSC strategic survey revealed […]
Kavli Affiliate: George Ricker | First 5 Authors: Ares Osborn, David J. Armstrong, Bryson Cale, Rafael Brahm, Robert A. Wittenmyer | Summary: We present the bright (V$_{mag} = 9.12$), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 pm 0.7$ days using archival photometry and radial […]
Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Nicholas Saunders, Samuel K. Grunblatt, , , | Summary: While the population of confirmed exoplanets continues to grow, the sample of confirmed transiting planets around evolved stars is still limited. We present the discovery and confirmation of a hot Jupiter orbiting TOI-2184 (TIC 176956893), a massive […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: The HERA Collaboration, Zara Abdurashidova, James E. Aguirre, Paul Alexander, Zaki S. Ali | Summary: We report upper-limits on the Epoch of Reionization (EoR) 21 cm power spectrum at redshifts 7.9 and 10.4 with 18 nights of data ($sim36$ hours of integration) from Phase I of […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Federica B. Bianco, Željko Ivezić, R. Lynne Jones, Melissa L. Graham, Phil Marshall | Summary: Vera C. Rubin Observatory is a ground-based astronomical facility under construction, a joint project of the National Science Foundation and the U.S. Department of Energy, designed to conduct a multi-purpose 10-year […]
