On the kinematic nature of apparent discs at high redshifts: Local counterparts are not dominated by ordered rotation but by tangentially anisotropic random motion

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bitao Wang, Yingjie Peng, Michele Cappellari, Hua Gao, Houjun Mo | Summary: It is not straightforward to physically interpret the apparent morphology of galaxies. Recent observations by James Webb Space Telescope (JWST) revealed a dominant galaxy population at high redshifts ($z>2$) that were visually classified as discs […]

Dynamics of the unitary Bose gas near a narrow Feshbach resonance: universal coherent atom-molecule oscillations

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Zhendong Zhang, Shu Nagata, Zhiqiang Wang, K. Levin | Summary: Quench experiments on a unitary Bose gas around a broad Feshbach resonance have led to the discovery of universal dynamics. This universality is manifested in the measured atomic momentum distributions where, asymptotically, a quasi-equilibrated metastable […]

FancyVideo: Towards Dynamic and Consistent Video Generation via Cross-frame Textual Guidance

Kavli Affiliate: Jing Wang | First 5 Authors: Jiasong Feng, Ao Ma, Jing Wang, Bo Cheng, Xiaodan Liang | Summary: Synthesizing motion-rich and temporally consistent videos remains a challenge in artificial intelligence, especially when dealing with extended durations. Existing text-to-video (T2V) models commonly employ spatial cross-attention for text control, equivalently guiding different frame generations without […]

From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zeyu Gao, Yingjie Peng, Kai Wang, Luis C. Ho, Alvio Renzini | Summary: The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional methods, including both parametric and non-parametric approaches, often fail to […]

Investigating the competition between the deconfinement and chiral phase transitions in light of the multimessenger observations of neutron stars

Kavli Affiliate: Renxin Xu | First 5 Authors: Wen-Li Yuan, Bikai Gao, Yan Yan, Bolin Li, Renxin Xu | Summary: We extend the parity doublet model for hadronic matter and study the possible presence of quark matter inside the cores of neutron stars with the Nambu-Jona-Lasinio (NJL) model. Considering the uncertainties of the QCD phase […]

Absence of High-mass Prestellar Cores in the Orion Giant Molecular Cloud

Kavli Affiliate: Ke Wang | First 5 Authors: Wenyu Jiao, Ke Wang, Fengwei Xu, , | Summary: A fundamental difference between "core-fed" and "clump-fed" star formation theories lies in the existence or absence of high-mass cores at the prestellar stage. However, only a handful of such cores have been observed. Here, different than previous search […]
