Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

JWST Reveals How Black Holes are Fed: Kiloparsec-scale Multiphase Filaments Feed Subkiloparsec Circumnuclear Disks

The Astrophysical Journal Letters
The Centaurus cluster is one of the most important archetypes of radio-mode active galactic nucleus (AGN) feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and regulate cooling and star formation.

Survey on Visualization of Information Diffusion over Networks

Computer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

Bridging the Bondi and Event Horizon Scales: 3D GRMHD Simulations Reveal X-shaped Radio Galaxy Morphology

The Astrophysical Journal Letters, 2022
Abstract X-shaped radio galaxies (XRGs) produce misaligned X-shaped jet pairs and make up ≲10% of radio galaxies. XRGs are thought to emerge in galaxies featuring a binary supermassive black hole (SMBH), SMBH merger, or large-scale ambient medium asymmetry.

Multiple Emission Regions in Jets of the Low-Luminosity Active Galactic Nucleus in NGC 4278

The Astrophysical Journal
The Large High Altitude Air Shower Observatory (LHAASO) has detected very-high-energy gamma rays from the low-ionization nuclear emission-line region galaxy NGC 4278, which has a low-luminosity active galactic nucleus (LLAGN) and symmetric, mildly ...

EXTENDED X-RAY EMISSIONS FROM THE RADIO GALAXY CENTAURUS B [PDF]

, 2020
Inverse-Compton X-rays from radio lobes and jets were long expected to determine the energy of electrons and magnetic field in radio lobes without assuming energy equipartition. In 1998, the radio galaxy Centaurus B became the first object that exhibited

Deep Chandra X-ray imaging of a nearby radio galaxy 4c+29.30 : X-ray/radio connection [PDF]

, 2012
We report results from our deep Chandra X-ray observations of a nearby radio galaxy, 4C+29.30 (z = 0.0647). The Chandra image resolves structures on sub-arcsec to arcsec scales, revealing complex X-ray morphology and detecting the main radio features ...

Galactic-scale evolution of classical and complex radio galaxies

Astronomy & Astrophysics
Context. Extragalactic jets, following their launching, exhibit a wide range of propagation orientations relative to the host galaxy’s principal axis. This initial (mis)alignment has been shown to exert a substantial influence on a jet’s subsequent large-
