Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Fupeng Zhang, Fupeng Zhang, , , | Summary: We explore extreme mass-ratio inspirals (EMRIs) in the co-evolution of massive black holes (MBHs) and nuclear star clusters (NSCs), which host diverse stellar populations across a wide range of masses. The dynamics are simulated self-consistently with GNC, which […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Xunda Sun, Xunda Sun, , , | Summary: We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the epoch of reionization (EoR). Our sample consists of 22 galaxies spanning the redshift range […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Paul Caucal, Paul Caucal, , , | Summary: We revisit the calculation of the next-to-leading order (NLO) corrections to dijet production in electron-ion collisions at small $x$. We focus on the back-to-back configuration where the relative transverse momentum $P_perp$ of the measured jets is much larger than […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Brenda L. Jones, Brenda L. Jones, , , | Summary: JWST has identified a large population of faint, broad-line active galactic nuclei (AGN) in the early universe that are powered by black holes (BHs) that often appear overmassive relative to their host galaxies. In this study, we […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, Zhen Cao, , , | Summary: Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), gamma-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by gamma-ray telescopes, particularly by the Large High Altitude Air Shower Observatory (LHAASO), have revealed a few tens of UHE sources, […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Kai Wu, Kai Wu, , , | Summary: As a continuation of DRAGON-II, we present the DRAGON-III project, which focuses on the simulations of million-body globular clusters and nuclear clusters over 10 Gyr. We report on its preliminary results on globular clusters. The first 100 Myr of […]
Kavli Affiliate: Jing Wang | First 5 Authors: Peng Chen, Peng Chen, , , | Summary: In this paper, we investigate the Milstein numerical scheme with step size $eta$ for a stochastic differential equation driven by multiplicative Brownian motion. Under some appropriate coefficient conditions, the continuous-time system and its discrete Milstein scheme approximation each possess […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Feng Yuan, , , | Summary: Cross-modal medical image synthesis research focuses on reconstructing missing imaging modalities from available ones to support clinical diagnosis. Driven by clinical necessities for flexible modality reconstruction, we explore K to N medical generation, where three critical challenges emerge: How […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Xiaoyang Chen, Xiaoyang Chen, , , | Summary: One of the most remarkable discoveries of JWST is a population of compact, red sources at z > 4, commonly referred to as Little Red Dots (LRDs). Spectroscopic identifications reported that most LRDs are active galactic nuclei (AGNs), which […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Tamjid Al Rahat, Tamjid Al Rahat, , , | Summary: OpenID Connect has revolutionized online authentication based on single sign-on (SSO) by providing a secure and convenient method for accessing multiple services with a single set of credentials. Despite its widespread adoption, critical security bugs in OpenID […]
