Causal bounds on cosmological angular correlation

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: We formulate a new hypothesis for causal coherence of gravitational quantum fluctuations, and test its predicted constraints on large-scale angular correlations in the cosmic microwave background (CMB). We posit that {it quantum fluctuations generate […]

Causal bounds on cosmological angular correlation

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: We test the hypothesis that angular correlations of gravitationally-induced temperature anisotropy in the cosmic microwave background (CMB) vanish over a range of large angular separations constrained by causality. Standard conformal geometry is used to […]

Revisiting Metastable Cosmic String Breaking

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Yuhei Nakayama, Satoshi Shirai, Keiichi Watanabe | Summary: Metastable cosmic strings appear in models of new physics with a two-step symmetry breaking $Gto Hto 1$, where $pi_1(H)neq 0$ and $pi_1(G)=0$. They decay via the monopole-antimonopole pair creation inside. Conventionally, the breaking rate has […]

A dynamical neural network approach for distributionally robust chance constrained Markov decision process

Kavli Affiliate: Jia Liu | First 5 Authors: Tian Xia, Jia Liu, Zhiping Chen, , | Summary: In this paper, we study the distributionally robust joint chance constrained Markov decision process. {Utilizing the logarithmic transformation technique,} we derive its deterministic reformulation with bi-convex terms under the moment-based uncertainty set. To cope with the non-convexity and […]

Observational Signatures of AGN Feedback in the Morphology and the Ionization States of Milky Way-like Galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nadia Qutob, Razieh Emami, Kung-Yi Su, Randall Smith, Lars Hernquist | Summary: We make an in-depth analysis of different AGN jet models’ signatures, inducing quiescence in galaxies with a halo mass of $10^{12} M_odot$. Three jet models, including cosmic ray-dominant, hot thermal, and precessing kinetic jets, are […]
