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

Posted by dbos November 28, 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 […]

Predicting the Age of Astronomical Transients from Real-Time Multivariate Time Series

Posted by dbos November 28, 2023MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hali Huang, Daniel Muthukrishna, Prajna Nair, Zimi Zhang, Michael Fausnaugh | Summary: Astronomical transients, such as supernovae and other rare stellar explosions, have been instrumental in some of the most significant discoveries in astronomy. New astronomical sky surveys will soon record unprecedented numbers of transients as sparsely […]

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 […]
