Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. I.Sample from the Early Data

Posted by dbos July 17, 2023Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Wei-Jian Guo, Hu Zou, Victoria Anne Fawcett, Rebecca Canning, Stephanie Juneau | Summary: Changing-look Active Galactic Nuclei (CL AGN) can be generally confirmed by the emergence (turn-on) or disappearance (turn-off) of broad emission lines, associated with a transient timescale (about $100sim5000$ days) that is much shorter than […]

The SocialAI School: Insights from Developmental Psychology Towards Artificial Socio-Cultural Agents

Posted by dbos July 15, 2023MIT

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Rémy Portelas, Peter Ford Dominey, Pierre-Yves Oudeyer, | Summary: Developmental psychologists have long-established the importance of socio-cognitive abilities in human intelligence. These abilities enable us to enter, participate and benefit from human culture. AI research on social interactive agents mostly concerns the emergence of culture […]

Large Language Models as Superpositions of Cultural Perspectives

Posted by dbos July 15, 2023MIT

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Masataka Sawayama, Rémy Portelas, Cédric Colas, Peter Ford Dominey | Summary: Large Language Models (LLMs) are often misleadingly recognized as having a personality or a set of values. We argue that an LLM can be seen as a superposition of perspectives with different values and […]

Collisions of red giants in galactic nuclei

Posted by dbos July 14, 2023Peking

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Taeho Ryu, Pau Amaro Seoane, Andrew M. Taylor, Sebastian T. Ohlmann, | Summary: In stellar-dense environments, stars can collide with each other. For collisions close to a supermassive black hole (SMBH), the collisional kinetic energy can be so large that the colliding stars can be completely […]

Antiadiabatic Small Polaron Formation in the Charge Transfer Insulator ErFeO3

Posted by dbos July 14, 2023Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ye-Jin Kim, Jocelyn L. Mendes, Young Jai Choi, Scott K. Cushing, | Summary: Small polaron formation is dominant across a range of condensed matter systems. Small polarons are usually studied in terms of ground-state transport and thermal fluctuations, but small polarons can also be created impulsively […]

Probing the Galactic Halo with RR Lyrae Stars — V. Chemistry, Kinematics, and Dynamically Tagged Groups

Posted by dbos July 13, 2023Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Jonathan Cabrera Garcia, Timothy C. Beers, Yang Huang, Xin-Yi Li, Gaochao Liu | Summary: We employ a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from the newly calibrated $P$–$phi_{31}$–$R_{21}$–[Fe/H] and $Gaia$ $G$-band $P$–$R_{21}$–[Fe/H] absolute magnitude-metallicity relations of Li et al., combined […]

Six-Point AdS Gluon Amplitudes from Flat Space and Factorization

Posted by dbos July 13, 2023UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Vasco Gonçalves, Maria Nocchi, Xinan Zhou, | Summary: We present a powerful new approach to compute tree-level higher-point holographic correlators. Our method only exploits the flat-space limit, where we point out a novel and important simplification, and factorization of amplitudes in AdS. In particular, […]
