Dynamics and spin alignment in massive, gravito-turbulent circumbinary discs around supermassive black hole binaries

Posted by dbos November 28, 2023December 11, 2023Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Martin A. Bourne, Davide Fiacconi, Debora Sijacki, Joanna M. Piotrowska, Sophie Koudmani | Summary: Parsec-scale separation supermassive black hole binaries in the centre of gas-rich galaxy merger remnants could be surrounded by massive circumbinary discs (CBDs). Black hole mass and spin evolution during the gas-rich binary inspiral […]

Optimal control of interacting active particles on complex landscapes

Posted by dbos November 28, 2023December 11, 2023Harvard

Kavli Affiliate: L. Mahadevan | First 5 Authors: Sumit Sinha, Vishaal Krishnan, L Mahadevan, , | Summary: Active many-body systems composed of many interacting degrees of freedom often operate out of equilibrium, giving rise to non-trivial emergent behaviors which can be functional in both evolved and engineered contexts. This naturally suggests the question of control […]

Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES

Posted by dbos November 28, 2023December 11, 2023Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Valentina D’Odorico, James S. Bolton, Lise Christensen, Annalisa De Cia, Erik Zackrisson | Summary: High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium and the reionisation of the Universe. However, these studies are […]

StreamFlow: Streamlined Multi-Frame Optical Flow Estimation for Video Sequences

Posted by dbos November 28, 2023December 11, 2023Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Occlusions between consecutive frames have long posed a significant challenge in optical flow estimation. The inherent ambiguity introduced by occlusions directly violates the brightness constancy constraint and considerably hinders pixel-to-pixel matching. To address this issue, multi-frame optical flow methods leverage […]

A Geometric Tension Dynamics Model of Epithelial Convergent Extension

Posted by dbos November 28, 2023UCSB

Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman, , | Summary: Convergent extension of epithelial tissue is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelial cells adhere to each other and […]

Low- and High-velocity ion{O}{6} in Milky Way-like Galaxies: the Role of Stellar Feedback

Posted by dbos November 27, 2023December 11, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhijie Zhang, Xiaoxia Zhang, Hui Li, Taotao Fang, Qingzheng Yu | Summary: Milky Way-type galaxies are surrounded by a warm-hot gaseous halo containing a considerable amount of baryons and metals. The kinematics and spatial distribution of highly-ionized ion species such as ion{O}{6} can be significantly affected by […]
