Tip of the iceberg: overmassive black holes at 4<z<7 found by JWST are not inconsistent with the local $mathcal{M}_{rm BH}$-$mathcal{M}_star$ relation

Posted by dbos Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Junyao Li, John D. Silverman, Yue Shen, Marta Volonteri, Knud Jahnke | Summary: JWST is revealing a new remarkable population of high-redshift ($zgtrsim4$), low-luminosity Active Galactic Nuclei (AGNs) in deep surveys and detecting the host galaxy stellar light in the most luminous and massive quasars at […]

SeD: Semantic-Aware Discriminator for Image Super-Resolution

Posted by dbos Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Bingchen Li, Xin Li, Hanxin Zhu, Yeying Jin, Ruoyu Feng | Summary: Generative Adversarial Networks (GANs) have been widely used to recover vivid textures in image super-resolution (SR) tasks. In particular, one discriminator is utilized to enable the SR network to learn the distribution of real-world […]

Small and Large Dust Cavities in Disks around mid-M Stars in Taurus

Posted by dbos Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Yangfan Shi, Feng Long, Gregory J. Herczeg, Daniel Harsono, Yao Liu | Summary: High-angular resolution imaging by ALMA has revealed the near-universality and diversity of substructures in protoplanetary disks. However, disks around M-type pre-main-sequence stars are still poorly sampled, despite the prevalence of M-dwarfs in the […]

The fundamental plane of black hole activity for low-luminosity radio active galactic nuclei across 1 < z < 4

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yijun Wang, Tao Wang, Luis C. Ho, Yuxing Zhong, Bin Luo | Summary: The fundamental plane of back hole activity (BHFP) describes the correlation between radio luminosity ($L_R$), X-ray luminosity ($L_X$), and black hole mass ($M_{BH}$). It reflects a connection between accretion disc and jet. However, […]

The FLAMINGO simulation view of cluster progenitors observed in the epoch of reionization with JWST

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Seunghwan Lim, Sandro Tacchella, Joop Schaye, Matthieu Schaller, Jakob M. Helton | Summary: Motivated by the recent JWST discovery of galaxy overdensities during the Epoch of Reionzation, we examine the physical properties of high-$z$ protoclusters and their evolution using the FLAMINGO simulation suite. We investigate the impact […]

Bit Rate Matching Algorithm Optimization in JPEG-AI Verification Model

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Panqi Jia, A. Burakhan Koyuncu, Jue Mao, Ze Cui, Yi Ma | Summary: The research on neural network (NN) based image compression has shown superior performance compared to classical compression frameworks. Unlike the hand-engineered transforms in the classical frameworks, NN-based models learn the non-linear transforms providing more […]

An Opacity-Free Method of Testing the Cosmic Distance Duality Relation Using Strongly Lensed Gravitational Wave Signals

Posted by dbos Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Shun-Jia Huang, En-Kun Li, Jian-dong Zhang, Xian Chen, Zucheng Gao | Summary: The cosmic distance duality relation (CDDR), expressed as DL(z) = (1 + z)2DA(z), plays an important role in modern cosmology. In this paper, we propose a new method of testing CDDR using strongly lensed gravitational […]
