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

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

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 […]

Buchdahl bound, photon ring, ISCO and radial acceleration in Einstein-æther theory

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Yi-Hsiung Hsu, Anthony Lasenby, Will Barker, Amel Durakovic, Michael Hobson | Summary: Spherically symmetric Einstein-{ae}ther (E{AE}) theory with a Maxwell-like kinetic term is revisited. We consider a general choice of the metric and the ae{}ther field, finding that:~(i) there is a gauge freedom allowing one always to […]

LHC EFT WG Note: Basis for Anomalous Quartic Gauge Couplings

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 […]

Connecting dust and outflows in AGN: the intriguing case of NGC 6860

Kavli Affiliate: Norbert Schulz | First 5 Authors: Ioanna Psaradaki, Missagh Mehdipour, Daniele Rogantini, Elisa Costantini, Norbert Schulz | Summary: Cosmic dust plays a crucial role in the evolution of galaxies, significantly influencing star formation and the interstellar medium. However, in active galactic nuclei (AGN), the role and origin of dust remain poorly understood. High-resolution […]

$θ$ dependence of $T_c$ in SU(2) Yang-Mills theory

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Norikazu Yamada, Masahito Yamazaki, Ryuichiro Kitano, , | Summary: We determine the $theta$ dependence of the confinement-deconfinement transition temperature $T_c$ for the 4d SU(2) pure Yang-Mills theory. We perform lattice numerical simulations on three spatial sizes $N_S=24$, $32$, $48$ with a fixed temporal size $N_T=8$. We introduce […]
