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

Kavli Affiliate: Anthony Lasenby | Summary:Spherically symmetric Einstein-æther (EÆ) theory with a Maxwell-like kinetic term is revisited. We consider a general choice of the metric and the æther field, finding that:~(i) there is a gauge freedom allowing one always to use a diagonal metric; and~(ii) the nature of the Maxwell equation forces the æther field […]

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

Kavli Affiliate: 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 X-ray spectroscopy is a powerful tool for probing the properties of dust in AGN. NGC […]
