Misaligned precessing jets are choked by the accretion disk wind
Wenbin Lu, Tatsuya Matsumoto, Christopher D. Matzner
We analytically and numerically study the hydrodynamic propagation of a precessing jet in the context of tidal disruption events (TDEs) where the star's angular momentum is misalig…
Near-Infrared Flux Distribution of Sgr A* from 2005-2022: Evidence for an Enhanced Accretion Episode in 2019
Grant C. Weldon, Tuan Do, Gunther Witzel +10
Sgr A* is the variable electromagnetic source associated with accretion onto the Galactic center supermassive black hole. While the near-infrared (NIR) variability of Sgr A* was sh…
Next-Generation Comprehensive Data-Driven Models of Solar Eruptive Events
Joel C. Allred, Graham S. Kerr, Meriem Alaoui +11
Solar flares and coronal mass ejections are interrelated phenomena that together are known as solar eruptive events. These are the main drivers of space weather and understanding t…
Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
Scalable and Accurate Self-supervised Multimodal Representation Learning without Aligned Video and Text Data
Vladislav Lialin, Stephen Rawls, David Chan +3
Scaling up weakly-supervised datasets has shown to be highly effective in the image-text domain and has contributed to most of the recent state-of-the-art computer vision and multi…
Multibeam Blind Search of Targeted SETI Observations toward 33 Exoplanet Systems with FAST
Xiao-Hang Luan, Zhen-Zhao Tao, Hai-Chen Zhao +8
The search for extraterrestrial intelligence (SETI) is to search for technosignatures associated with extraterrestrial life, such as engineered radio signals. In this paper, we app…
