Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hannah Gulick, Hiroki Yoneda, Tadayuki Takahashi, Claire Chen, Kazuhiro Nakazawa | Summary: We present measurements of the afterglow signatures in NaI(Tl) and CsI(Tl) detector modules as part of the Background and Transient Observer (BTO) mission detector trade-study. BTO is a NASA Student Collaboration Project flying on the […]

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yann Gouttenoire, Stephen F. King, Rishav Roshan, Xin Wang, Graham White | Summary: One of the simplest standard model extensions leading to a domain wall network is a real scalar $S$ with a $mathcal{Z}_2$ symmetry spontaneously broken during universe evolution. Motivated by the swampland program, we explore […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~10^51 erg depending on the critical density for the onset of flavor […]

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Yue Nan, Masahiro Takada, , | Summary: We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(theta)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show […]

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Naoki Itoh, Hugo Allaire, Tokihiro Ikeda, Shunsaku Nagasawa, Shinji Okada | Summary: We investigated the energy dependence of the number of triggered pixels, or cluster size, when charged particles are detected using the TimePix3 detector with a silicon sensor. We measured protons in the range of 1.5~3.3 […]

Kavli Affiliate: John D. Silverman | First 5 Authors: Qinyue Fei, John D. Silverman, Seiji Fujimoto, Ran Wang, Luis C. Ho | Summary: We conduct a study of the gas kinematics of two quasar host galaxies at $zgtrsim6$ traced by the [CII] emission line using ALMA. By combining deep observations at both low and high […]

Kavli Affiliate: Jia Liu | First 5 Authors: Ziyue Luo, Jia Liu, Myungjin Lee, Ness B. Shroff, | Summary: The recent explosive growth of deep learning (DL) models has necessitated a compelling need for efficient job scheduling for distributed deep learning training with mixed parallelisms (DDLwMP) in GPU clusters. This paper proposes an adaptive shortest-remaining-processing-time-first […]

Kavli Affiliate: Masahiro Takada | First 5 Authors: Kanmi Nose, Masahiro Takada, Ryo Terasawa, , | Summary: In a wide-area spectroscopic survey of galaxies, it is nearly impossible to obtain a homogeneous sample of galaxies with respect to galaxy properties such as stellar mass and host halo mass across a range of redshifts. Despite the […]
