TL;DR: In this paper, a comprehensive synthesis model for the AGN evolution and the growth of supermassive black holes in the Universe is presented, where the continuity equation for SMBH mass function is solved using the locally determined one as a boundary condition, and the hard X-ray luminosity function as tracer of the growth rate distribution, supplemented with a luminosity-dependent bolometric correction and an absorbing column distribution.

TL;DR: Multiwavelength afterglow of GRB 221009A is well-described by a smoothly broken power law spectrum. The complexity of data reduction due to the unprecedented brightness and Galactic plane location is addressed. Three interpretations of the data are presented.

TL;DR: In this article, the authors investigate the launching and stability of extragalactic jets through magnetohydrodynamic simulations of jet evolution, and they show that the outflow is unstable to the m = 1 kink instability.

TL;DR: In this article, a series of three-dimensional hydrodynamical simulations of central AGN driven jets in a dynamic, cosmologically evolved galaxy cluster are presented, and the authors find that large-scale motions of cluster gas disrupt the AGN jets, causing energy to be distributed throughout the centre of the cluster, rather than confined to a narrow angle around the jet axis.
