Gravitational waves from type II axion-like curvaton model and its implication for NANOGrav result

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, , , | Summary: The recent report of NANOGrav is gathering attention since its signal can be explained by the stochastic gravitational waves (GWs) with $Omega_{rm GW}sim 10^{-9}$ at $fsim 10^{-8}$Hz. The PBH formation scenario is one of the candidates for the NANOGrav […]

CO excitation, molecular gas density and interstellar radiation field in local and high-redshift galaxies

Kavli Affiliate: John Silverman | First 5 Authors: Daizhong Liu, Emanuele Daddi, Eva Schinnerer, Toshiki Saito, Adam Leroy | Summary: We study the Carbon Monoxide (CO) excitation, mean molecular gas density and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local to high redshift (z~0-6), selected based on detections of […]

Quantum Information Theory of the Gravitational Anomaly

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Domenico Orlando, Masataka Watanabe, , | Summary: We show that the standard notion of entanglement is not defined for gravitationally anomalous two-dimensional theories because they do not admit a local tensor factorization of the Hilbert space into local Hilbert spaces. Qualitatively, the modular flow cannot […]

Distributionally robust second-order stochastic dominance constrained optimization with Wasserstein ball

Kavli Affiliate: Jia Liu | First 5 Authors: Yu Mei, Jia Liu, Zhiping Chen, , | Summary: We consider a distributionally robust second-order stochastic dominance constrained optimization problem. We require the dominance constraints hold with respect to all probability distributions in a Wasserstein ball centered at the empirical distribution. We adopt the sample approximation approach […]

Optical follow-up observation for GW event S190510g using Subaru/Hyper Suprime-Cam

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Takayuki Ohgami, Nozomu Tominaga, Yousuke Utsumi, Yuu Niino, Masaomi Tanaka | Summary: A gravitational wave event, S190510g, which was classified as a binary-neutron-star coalescence at the time of preliminary alert, was detected by LIGO/Virgo collaboration on May 10, 2019. At 1.7 hours after the issue of its […]

Abelian envelopes of exact categories and highest weight categories

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define admissible and weakly admissible subcategories in exact categories and prove that the former induce semi-orthogonal decompositions on the derived categories. We develop the theory of thin exact categories, an exact-category analogue of triangulated categories generated by exceptional […]

The Atacama Cosmology Telescope: Detection of mm-wave transient sources

Kavli Affiliate: David Spergel | First 5 Authors: Sigurd Naess, Nick Battaglia, J. Richard Bond, Erminia Calabrese, Steve K. Choi | Summary: We report on the serendipitous discovery of three transient mm-wave sources using data from the Atacama Cosmology Telescope. The first, detected at RA = 273.8138, dec = -49.4628 at ${sim}50sigma$ total, brightened from […]
