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: Masahiro Takada | First 5 Authors: Ken Osato, Takahiro Nishimichi, Masahiro Takada, , | Summary: The high-precision measurement of spatial clustering of emission line galaxies (ELGs) is a primary objective for upcoming cosmological spectroscopic surveys. The source of strong emission of ELGs is nebular emission from surrounding ionized gas irradiated by massive short-lived […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Magnus Axelsson, Chris Done, Tadayuki Takahashi, | Summary: The nature and geometry of the accretion flow in the low/hard state of black hole binaries is currently controversial. While most properties are generally explained in the truncated disc/hot inner flow model, the detection of a broad […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Divya Rana, Surhud More, Hironao Miyatake, Takahiro Nishimichi, Masahiro Takada | Summary: We utilize the galaxy shape catalogue from the first-year data release of the Subaru Hyper Suprime-cam Survey (HSC) to study the dark matter content of galaxy groups in the Universe using weak lensing. We use […]
Kavli Affiliate: Tom Melia | First 5 Authors: Andrew J. Larkoski, Tom Melia, , , | Summary: Despite being the overwhelming majority of events produced in hadron or heavy ion collisions, minimum bias events do not enjoy a robust first-principles theoretical description as their dynamics are dominated by low-energy quantum chromodynamics. In this paper, we […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kai Murai, Hiromasa Nakatsuka, , | Summary: Primordial black hole (PBH) is a fascinating candidate for the origin of binary merger events observed by LIGO-Virgo collaboration. The spatial distribution of PBHs at formation is an important feature to estimate the merger rate. We investigate the […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Hitoshi Murayama, Ofri Telem, | Summary: We investigate the IR phases of non-supersymmetric (non-SUSY) $SO(N_c)$ gauge theories with $N_F$ fermions in the vector representation obtained by perturbing the SUSY theory with anomaly mediated SUSY breaking (AMSB). We find that of the wide variety […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Xiangchong Li, Hironao Miyatake, Wentao Luo, Surhud More, Masamune Oguri | Summary: We present the galaxy shear catalog that will be used for the three-year cosmological weak gravitational lensing analyses using data from the Wide layer of the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) Survey. The […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Samantha Lynn Stever, Tommaso Ghigna, Mayu Tominaga, Giuseppe Puglisi, Masahiro Tsujimoto | Summary: Systematic effects arising from cosmic rays have been shown to be a significant threat to space telescopes using high-sensitivity bolometers. The LiteBIRD space mission aims to measure the polarised Cosmic Microwave Background with unprecedented […]
Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Joshua Eby, Satoshi Shirai, Yevgeny V. Stadnik, Volodymyr Takhistov, | Summary: Axions constituting dark matter (DM) are often considered to form a non-relativistic oscillating field. We explore bursts of relativistic axions from transient astrophysical sources, such as axion star explosions, where the sources are initially non-relativistic. […]
