Nucleon Decay as a Probe of Flavor Symmetry: The Case of Fake Unification

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Keiichi Watanabe, , | Summary: This paper explores nucleon decay within the framework of a "fake Grand Unified Theory (GUT)" combined with the Froggatt-Nielsen (FN) mechanism. In this fake GUT framework, quarks and leptons may have distinct high-energy origins but fit into complete […]

Configuration interaction relativistic Hartree-Fock model

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Yi Fei Niu, Wen Hui Long, , | Summary: The configuration interaction relativistic Hartree-Fock (CI-RHF) model is developed in this work. Compared to the conventional configuration interaction shell model calculations, the CI-RHF model can be applied to study the structural properties of a wide range […]

Prograde and retrograde stars in nuclear cluster mergers. Evolution of the supermassive black hole binary and the host galactic nucleus

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Alessandra Mastrobuono-Battisti, Pau Amaro Seoane, Màrius Josep Fullana i Alfonso, Chingis Omarov, Denis Yurin | Summary: We address the orbital distribution of stars in merging nuclear star clusters (NSCs) and the subsequent effects on supermassive black hole binary (SMBHB) evolution. We ran direct-summation $N$-body simulations with […]

Repeating transients in galactic nuclei: confronting observations with theory

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Petra Suková, Francesco Tombesi, Dheeraj R. Pasham, Michal Zajaček, Thomas Wevers | Summary: In the last few years, a mysterious new class of astrophysical objects has been uncovered. These are spatially coincident with the nuclei of external galaxies and show X-ray variations that repeat on timescales […]

The Host Galaxy (If Any) of the Little Red Dots

Kavli Affiliate: Luis C. Ho | First 5 Authors: Chang-Hao Chen, Luis C. Ho, Ruancun Li, Ming-Yang Zhuang, | Summary: We investigate the host galaxy properties of eight little red dots (LRDs) selected from the JWST UNCOVER survey, applying a new technique ({ttstring GalfitS}) to simultaneously fit the morphology and spectral energy distribution using multi-band […]

On non-supersymmetric heterotic branes

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Justin Kaidi, Yuji Tachikawa, Kazuya Yonekura, , | Summary: A uniform construction of non-supersymmetric 0-, 4-, 6- and 7-branes in heterotic string theory was announced and outlined in our letter cite{Kaidi:2023tqo}. In this full paper, we provide details on their properties. Among other things, we discuss the […]

ALMA Spectral Survey of An eruptive Young star, V883 Ori (ASSAY): II. Freshly Sublimated Complex Organic Molecules (COMs) in the Keplerian Disk

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Jae-Hong Jeong, Jeong-Eun Lee, Seonjae Lee, Giseon Baek, Ji-Hyun Kang | Summary: We present an investigation of Complex Organic Molecules (COMs) in the spatially resolved Keplerian disk around V883 Ori, an eruptive young star, based on a spectral survey carried out with ALMA in Band 6 […]
