Evidence of mutually exclusive outflow forms from a black hole X-ray binary
Zuobin Zhang, Jiachen Jiang, Francesco Carotenuto +13
Accretion onto black holes often leads to the launch of outflows that significantly influence their surrounding environments. The two primary forms of these outflows are X-ray disk…

Getting More Out of Black Hole Superradiance: a Statistically Rigorous Approach to Ultralight Boson Constraints from Black Hole Spin Measurements
Sebastian Hoof, David J. E. Marsh, Júlia Sisk-Reynés +2
Black hole (BH) superradiance can provide strong constraints on the properties of ultralight bosons (ULBs). While most of the previous work has focused on the theoretical predictio…

Cold fronts in galaxy clusters I: A case for the large-scale global eigen modes in unmagnetized and weakly magnetized cluster core
Prakriti Pal Choudhury, Christopher S. Reynolds
Galaxy clusters show large-scale azimuthal X-ray surface brightness fluctuations known as cold fronts. Cold fronts are argued to originate due to sloshing driven by sub-halo passag…
