Kavli Affiliate: T. Higuchi | First 5 Authors: F. Abudinén, I. Adachi, R. Adak, K. Adamczyk, L. Aggarwal | Summary: We report a measurement of the branching fraction of $B to K^{ast}(892)ell^+ell^-$ decays, where $ell^+ell^- = mu^+mu^-$ or $e^+e^-$, using electron-positron collisions recorded at an energy at or near the $Upsilon(4S)$ mass and corresponding to […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Nick Ekanger, Shunsaku Horiuchi, Kei Kotake, Kohsuke Sumiyoshi, | Summary: In the absence of high-statistics supernova neutrino measurements, estimates of the diffuse supernova neutrino background (DSNB) hinge on the precision of simulations of core-collapse supernovae (CCSNe). Understanding the cooling phase of protoneutron star (PNS) evolution ($gtrsim1,{rm s}$ […]

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Yuki Isobe, Masami Ouchi, Kimihiko Nakajima, Shinobu Ozaki, Nicolas Bouche | Summary: We present kinematics of 6 local extremely metal-poor galaxies (EMPGs) with low metallicities ($0.016-0.098 Z_{odot}$) and low stellar masses ($10^{4.7}-10^{7.6} M_{odot}$). Taking deep medium-high resolution ($Rsim7500$) integral-field spectra with 8.2-m Subaru, we resolve the small […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Renan Alves de Oliveira, Francisco Villaescusa-Navarro, Shirley Ho | Summary: We build a field level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists of two convolutional neural networks trained to output the nonlinear displacements and […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Siyu He, Francisco Villaescusa-Navarro, Shirley Ho | Summary: We train a neural network model to predict the full phase space evolution of cosmological N-body simulations. Its success implies that the neural network model is accurately approximating the Green’s function expansion that relates […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Sugumi Kanno, Misao Sasaki, , , | Summary: We compute the leading order non-Gaussianity, i.e., the bispectrum, of the tensor perturbation in the general $alpha$-vacuum on de Sitter space in general relativity. In addition to the well-known Bunch-Davies (BD) vacuum, there exits an infinite number of de […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Masahito Yamazaki, Yunqin Zheng, , | Summary: We explore an exact duality in $(2+1)$d between the fermionization of a bosonic theory with a $mathbb{Z}_2$ subsystem symmetry and a fermionic theory with a $mathbb{Z}_2$ subsystem fermion parity symmetry. A typical example is the duality between the […]
