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

Posted by dbos Peking

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

Posted by dbos Peking

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 […]

Systematic effects on lensing reconstruction from a patchwork of CMB polarization maps

Posted by dbos Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Ryo Nagata, Toshiya Namikawa, , , | Summary: We investigate the tolerance for systematic errors in lensing analysis applied to a patchwork map of Cosmic Microwave Background polarization. We focus on the properties of the individual polarization maps that comprise the patchwork and discuss the associated calibration […]

Constraining Ultralight ALP Dark Matter in Light of Cosmic Birefringence

Posted by dbos Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Dongdong Zhang, Elisa G. M. Ferreira, Ippei Obata, Toshiya Namikawa, | Summary: Cosmic birefringence, the observed rotation of the polarization plane of the cosmic microwave background (CMB), serves as a compelling probe for parity-violating physics beyond the Standard Model. This study explores the potential of ultralight axion-like […]

Unveiling the Cosmic Chemistry: Revisiting the Mass-Metallicity Relation with JWST/NIRSpec at 4 < z < 10

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Arnab Sarkar, Priyanka Chakraborty, Mark Vogelsberger, Micheal McDoland, Paul Torrey | Summary: We present star formation rates (SFR), the mass-metallicity relation (MZR), and the SFR-dependent MZR across redshifts 4 to 10 using 81 star-forming galaxies observed by the JWST NIRSpec employing both low-resolution PRISM and medium-resolution gratings, […]

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

Posted by dbos Peking

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 […]

Field-level Emulation of Cosmic Structure Formation with Cosmology and Redshift Dependence

Posted by dbos Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Francisco Villaescusa-Navarro, Shirley Ho, David N. Spergel | Summary: We present a field-level emulator for large-scale structure, capturing the cosmology dependence and the time evolution of cosmic structure formation. The emulator maps linear displacement fields to their corresponding nonlinear displacements from N-body […]
