Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Anirban Roy, Blake D. Sherwin, Nicholas Battaglia, David N. Spergel | Summary: We propose a new reionization probe that uses cosmic microwave background (CMB) observations; the cross-correlation between fluctuations in the CMB optical depth which probes the integrated electron density, $deltatau$, and the Compton $y$-map […]

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Ryo Nagata, Toshiya Namikawa, , , | Summary: Impacts of observational systematic errors on the lensing analysis of the cosmic microwave background (CMB) polarization are investigated by numerical simulations. We model errors of gain, angle, and pointing in observation of the CMB polarization and simulate polarization fields […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Deheng Song, Oscar Macias, Shunsaku Horiuchi, Roland M. Crocker, David M. Nataf | Summary: Millisecond pulsars are very likely the main source of gamma-ray emission from globular clusters. However, the relative contributions of two separate emission processes–curvature radiation from millisecond pulsar magnetospheres vs. inverse Compton emission from […]

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Kenji Kiuchi, Shunsuke Adachi, Aamir M. Ali, Kam Arnold, Peter Ashton | Summary: The Simons Observatory (SO) is a cosmic microwave background (CMB) experiment from the Atacama Desert in Chile comprising three small-aperture telescopes (SATs) and one large-aperture telescope (LAT). In total, SO will field over 60,000 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
