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 […]

FLTrust: Byzantine-robust Federated Learning via Trust Bootstrapping

Kavli Affiliate: Jia Liu | First 5 Authors: Xiaoyu Cao, Minghong Fang, Jia Liu, Neil Zhenqiang Gong, | Summary: Byzantine-robust federated learning aims to enable a service provider to learn an accurate global model when a bounded number of clients are malicious. The key idea of existing Byzantine-robust federated learning methods is that the service […]

Gravitational wave constraints on the primordial black hole dominated early universe

Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Chunshan Lin, Misao Sasaki, , | Summary: We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually dominate and reheat the universe by Hawking evaporation. The initial PBH density […]

W=0 Complex Structure Moduli Stabilization on CM-type K3 x K3 Orbifolds:—Arithmetic, Geometry and Particle Physics—

Kavli Affiliate: Taizan Watari | First 5 Authors: Keita Kanno, Taizan Watari, , , | Summary: It is an important question in string compactification whether complex structure moduli stabilization inevitably ends up with a vacuum expectation value of the superpotential < W > of the order of the Planck scale cubed. Any thoughts on volume […]

Minkowski functionals and the nonlinear perturbation theory in the large-scale structure: second-order effects

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Takahiko Matsubara, Chiaki Hikage, Satoshi Kuriki, , | Summary: The second-order formula of Minkowski functionals in weakly non-Gaussian fields is compared with the numerical $N$-body simulations. Recently, weakly non-Gaussian formula of Minkowski functionals is extended to include the second-order effects of non-Gaussianity in general dimensions. We apply […]

Constraints on the rate of supernovae lasting for more than a year from Subaru/Hyper Suprime-Cam

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Takashi J. Moriya, Ji-an Jiang, Naoki Yasuda, Mitsuru Kokubo, Kojiro Kawana | Summary: Some supernovae such as pair-instability supernovae are predicted to have the duration of more than a year in the observer frame. To constrain the rates of supernovae lasting for more than a year, we […]
