Effects of ultra-fast outflows on X-ray time lags in AGN

Posted by dbos November 5, 2024November 18, 2024MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Erin Kara, Stefano Bianchi, William Alston | Summary: The time lag between soft and hard X-ray photons has been observed in many active galactic nuclei (AGN) and can reveal the accretion process and geometry around supermassive black holes (SMBHs). High-frequency Fe K and […]

Analysis of Multi-epoch JWST Images of $sim 300$ Little Red Dots: Tentative Detection of Variability in a Minority of Sources

Posted by dbos November 5, 2024November 18, 2024Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Zijian Zhang, Linhua Jiang, Weiyang Liu, Luis C. Ho, | Summary: James Webb Space Telescope (JWST) has revealed a population of red and compact sources at $z gtrsim 5$ known as "Little Red Dots" (LRDs) that are likely active galactic nuclei (AGNs). Here we present a comprehensive […]

LHC EFT WG Note: Basis for Anomalous Quartic Gauge Couplings

Posted by dbos November 4, 2024November 18, 2024Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Gauthier Durieux, Grant N. Remmen, Nicholas L. Rodd, O. J. P. Éboli, M. C. Gonzalez-Garcia | Summary: In this note, we give a definitive basis for the dimension-eight operators leading to quartic — but no cubic — interactions among electroweak gauge bosons. These are often called anomalous […]
