Nearly-zero large-angle anisotropy of the cosmic microwave background

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: The global isotropy of the universe is analyzed on the scale of the cosmic horizon, using the angular correlation function $C(Theta)$ of cosmic microwave background (CMB) temperature at large angular separation $Theta$. Even-parity correlation […]

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 […]

Morphologies of Bright Complex Fast Radio Bursts with CHIME/FRB Voltage Data

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Jakob T. Faber, Daniele Michilli, Ryan Mckinven, Jianing Su, Aaron B. Pearlman | Summary: We present the discovery of twelve thus far non-repeating fast radio burst (FRB) sources, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources were selected from a database comprising […]

Rapid dimming followed by a state transition: a study of the highly variable nuclear transient AT 2019avd over 1000+ days

Kavli Affiliate: Ronald Remillard | First 5 Authors: Yanan Wang, Dheeraj R. Pasham, Diego Altamirano, Andres Gurpide, Noel Castro Segura | Summary: The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our 1000+ days NICER, […]
