Kavli Affiliate: Roberto Maiolino | First 5 Authors: Roberto Maiolino, Jan Scholtz, Joris Witstok, Stefano Carniani, Francesco D’Eugenio | Summary: Black holes with masses in excess of several billion solar masses have been found at redshifts 6-7.5, when the universe was less than 1 Gyr old. The existence of such supermassive black holes already in […]
Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Daniele Rogantini, Stefano Bianchi, Matteo Guainazzi | Summary: Ultra-fast outflows (UFOs) have been revealed in a large number of active galactic nuclei (AGN) and are regarded as promising candidates for AGN feedback on the host galaxy. The nature and launching mechanism of UFOs […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S. Bennett, Debora Sijacki, Tiago Costa, Nicolas Laporte, Callum Witten | Summary: High-redshift quasars ($zgtrsim6$), powered by black holes (BHs) with large inferred masses, imply rapid BH growth in the early Universe. The most extreme examples have inferred masses of $sim ! 10^9,$M$_odot$ at $z = […]
Kavli Affiliate: Jiansheng Chen | First 5 Authors: Jingyuan Zhu, Huimin Ma, Jiansheng Chen, Jian Yuan | Summary: Realistic and diverse 3D shape generation is helpful for a wide variety of applications such as virtual reality, gaming, and animation. Modern generative models, such as GANs and diffusion models, learn from large-scale datasets and generate new […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Rainer Spurzem, Albrecht Kamlah | Summary: Dense star clusters are spectacular self-gravitating stellar systems in our Galaxy and across the Universe – in many respects. They populate disks and spheroids of galaxies as well as almost every galactic center. In massive elliptical galaxies nuclear clusters harbor supermassive […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Yihuan Di, Yuan Li, Feng Yuan, Fangzheng Shi, Mirielle Caradonna | Summary: We perform high-resolution hydrodynamical simulations using the framework of {it MACER} to investigate supermassive black hole (SMBH) feeding and feedback in a massive compact galaxy, which has a small effective radius but a large stellar […]
Kavli Affiliate: Biao Huang | First 5 Authors: Zhiyinan Huang, Jinfeng Liu, Biao Huang (University of Alberta) | Summary: We propose a robust nonlinear model predictive control design with generalized zone tracking (ZMPC) in this work. The proposed ZMPC has guaranteed convergence into the target zone in the presence of bounded disturbance. The proposed approach […]
Kavli Affiliate: Jin Kang, Dwight Bergles | Authors: Yung-Tian A. Gau, Eric Hsu, Jaepyeong Cha, Rebecca W. Pak, Loren L. Looger, Jin U. Kang and Dwight E. Bergles | Summary: Astrocytes are a direct target of neuromodulators and can influence neuronal activity on broad spatial and temporal scales through their close proximity to synapses. However, […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Bridget C. Andersen, Chitrang Patel, Charanjot Brar, P. J. Boyle, Emmanuel Fonseca | Summary: Fast radio bursts (FRBs) are bright radio transients of micro-to-millisecond duration and unknown extragalactic origin. Central to the mystery of FRBs are their extremely high characteristic energies, which surpass the typical energies […]
Kavli Affiliate: Vincent Ferrera, Daphna Shohamy, Larry Abbott | Authors: Kenneth Kay, Natalie Biderman, Ramin Khajeh, Manuel Beiran, Christopher J Cueva, Daphna Shohamy, Greg Jensen, Xue-Xin Wei, Vincent P Ferrera and L F Abbott | Summary: Relational cognition — the ability to infer relationships that generalize to novel combinations of objects — is fundamental to […]
