Single-Star Warm-Jupiter Systems Tend to Be Aligned, Even Around Hot Stellar Hosts: No $T_{rm eff}-λ$ Dependency

Posted by dbos MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Xian-Yu Wang, Malena Rice, Songhu Wang, Shubham Kanodia, Fei Dai | Summary: The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters’ tidal detachment likely preserves their primordial obliquity. However, the sample size of warm-Jupiter […]

Demonstration of hybrid foreground removal on CHIME data

Posted by dbos MIT

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Haochen Wang, Kiyoshi Masui, Kevin Bandura, Arnab Chakraborty, Matt Dobbs | Summary: The main challenge of 21 cm cosmology experiments is astrophysical foregrounds which are difficult to separate from the signal due to telescope systematics. An earlier study has shown that foreground residuals induced by antenna gain […]

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, […]
