Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We measure the lifetime of the $D_s^+$ meson using a data sample of 207 fb$^{-1}$ collected by the Belle II experiment running at the SuperKEKB asymmetric-energy $e^+ e^-$ collider. The lifetime is determined by […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Gabriel Maheson, Roberto Maiolino, Mirko Curti, Ryan Sanders, Sandro Tacchella | Summary: We explore the dependence of dust attenuation, as traced by the $rm H_{alpha}/rm H_{beta}$ Balmer decrement, on galactic properties by using a large sample of SDSS spectra. We use both Partial Correlation Coefficients (PCC) and […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Shichuan Chen, Yong Gao, Enping Zhou, Renxin Xu, | Summary: Can pulsar-like compact objects release further huge free energy besides the kinematic energy of rotation? This is actually relevant to the equation of state of cold supra-nuclear matter, which is still under hot debate. Enormous energy is […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Patrick Obin Sturm, Saketh Bharadwaj, Sam Silva, Max Tegmark | Summary: Discovering conservation laws for a given dynamical system is important but challenging. In a theorist setup (differential equations and basis functions are both known), we propose the Sparse Invariant Detector (SID), an algorithm that […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, , , | Summary: We review the theoretical underpinnings, evolutionary status, calibrations and current applications of three bright Population II extragalactic distance indicators: Tip of the Red Giant Branch (TRGB) stars, RR Lyrae variables and J-Branch Asymptotic Giant Branch (JAGB/Carbon) […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Zhiyuan Ji, Christina C. Williams, Sandro Tacchella, Katherine A. Suess, William M. Baker | Summary: We present a spatially resolved study of stellar populations in 6 galaxies with stellar masses $M_*sim10^{10}M_odot$ at $zsim3.7$ using 14-filter JWST/NIRCam imaging from the JADES and JEMS surveys. The 6 galaxies are […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Ryodai Kawaguchi, Tomohiro Fujita, Misao Sasaki, , | Summary: We study a single-field inflation model in which the inflaton potential has an upward step between two slow-roll regimes by taking into account the finite width of the step. We calculate the probability distribution function (PDF) of the […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Xiyan Peng, Zhaoxiang Qi, Tianmeng Zhang, Zhenyu Wu, Zhimin Zhou | Summary: We present the astrometric calibration of the Beijing-Arizona Sky Survey (BASS). The BASS astrometry was tied to the International Celestial Reference Frame via the emph{Gaia} Data Release 2 reference catalog. For effects that were stable […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Huangzhao Zhang, Zhi Jin, Ge Li, | Summary: Bug localization, which is used to help programmers identify the location of bugs in source code, is an essential task in software development. Researchers have already made efforts to harness the powerful deep learning (DL) techniques to […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Enia Xhakaj, Alexie Leauthaud, Johannes Lange, Elisabeth Krause, Andrew Hearin | Summary: We propose that observations of super-massive galaxies contain cosmological constraining power similar to conventional cluster cosmology, and we provide promising indications that the associated systematic errors are comparably easier to control. We consider a […]
