FREAK: Frequency-modulated High-fidelity and Real-time Audio-driven Talking Portrait Synthesis

Kavli Affiliate: Yi Zhou | First 5 Authors: Ziqi Ni, Ao Fu, Yi Zhou, , | Summary: Achieving high-fidelity lip-speech synchronization in audio-driven talking portrait synthesis remains challenging. While multi-stage pipelines or diffusion models yield high-quality results, they suffer from high computational costs. Some approaches perform well on specific individuals with low resources, yet still […]

Quasi-periodic oscillations of GHz-band polarization in a black hole

Kavli Affiliate: Luis C. Ho | First 5 Authors: Wei Wang, Jiashi Chen, Pengfu Tian, Luis C. Ho, Xiaohui Sun | Summary: Relativistic jets from accreting black holes (BHs) radiate non-thermal emission which is highly variable in different time scales. Magnetic fields anchored to a rotating BH or accretion disc accelerate and collimate jets of […]

The Convergence of Heavy and Light Seeds to Overmassive Black Holes at Cosmic Dawn

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltan Haiman, Luis C. Ho, Ken Ohsuga | Summary: The James Webb Space Telescope (JWST) has revealed low-luminosity active galactic nuclei (AGNs) at redshifts of $zgtrsim 4-7$, many of which host accreting massive black holes (BHs) with BH-to-galaxy mass ($M_{rm BH}/M_{star}$) ratios exceeding […]

Medium-band Astrophysics with the Grism of NIRCam In Frontier fields (MAGNIF): Spectroscopic Census of H$α$ Luminosity Functions and Cosmic Star Formation at $zsim 4.5$ and 6.3

Kavli Affiliate: Linhua Jiang | First 5 Authors: Shuqi Fu, Fengwu Sun, Linhua Jiang, Xiaojing Lin, Jose M. Diego | Summary: We measure H$alpha$ luminosity functions (LFs) at redshifts $z sim 4.5$ and 6.3 using the JWST MAGNIF (Medium-band Astrophysics with the Grism of NIRCam In Frontier fields) survey. MAGNIF obtained NIRCam grism spectra with […]

The optical and infrared are connected

Kavli Affiliate: David N. Spergel | First 5 Authors: Christian K. Jespersen, Peter Melchior, David N. Spergel, Andy D. Goulding, ChangHoon Hahn | Summary: Galaxies are often modelled as composites of separable components with distinct spectral signatures, implying that different wavelength ranges are only weakly correlated. They are not. We present a data-driven model which […]
