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 […]
Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, , , , | Summary: This is the second part of the paper which proves the compatibility of pushforward along a proper morphism of an ‘{e}tale constructible sheaf and the pushforward of its characteristic cycle up to $p$-torsion. In this second part, we show a […]
Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, , , , | Summary: We prove the compatibility of pushforward along a proper morphism of an ‘{e}tale constructible sheaf and the pushforward of its characteristic cycle up to $p$-torsion. This was conjectured by Takeshi Saito. For this, we revisit the construction of the characteristic […]
Kavli Affiliate: Jia Liu | First 5 Authors: Donghui Li, Jia Liu, Fang Liu, Wenhua Zhang, Andi Zhang | Summary: Deep learning based semantic segmentation is one of the popular methods in remote sensing image segmentation. In this paper, a network based on the widely used encoderdecoder architecture is proposed to accomplish the synthetic aperture […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Ji-an Jiang, Naoki Yasuda, Keiichi Maeda, Nozomu Tominaga, Mamoru Doi | Summary: In this letter we report a discovery of an ultra-luminous fast evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by using the Hyper Suprime-Cam (HSC) mounted on the 8.2m Subaru telescope. The […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Ji-an Jiang, Naoki Yasuda, Keiichi Maeda, Nozomu Tominaga, Mamoru Doi | Summary: In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by using the Hyper Suprime-Cam (HSC) mounted on the 8.2 m Subaru telescope. The […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Shunsaku Nagasawa, Tomoko Kawate, Noriyuki Narukage, Tadayuki Takahashi, Amir Caspi | Summary: We conduct a wide-band X-ray spectral analysis in the energy range of 1.5-100 keV to study the time evolution of the M7.6 class flare of 2016 July 23, with the Miniature X-ray Solar Spectrometer (MinXSS) […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Johannes R. Eskilt, Eiichiro Komatsu, , , | Summary: The observed pattern of linear polarization of the cosmic microwave background (CMB) photons is a sensitive probe of physics violating parity symmetry under inversion of spatial coordinates. A new parity-violating interaction might have rotated the plane of linear […]
