Rapid dimming followed by a state transition: a study of the highly variable nuclear transient AT 2019avd over 1000+ days

Kavli Affiliate: Ronald Remillard | First 5 Authors: Yanan Wang, Dheeraj R. Pasham, Diego Altamirano, Andres Gurpide, Noel Castro Segura | Summary: The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our 1000+ days NICER, […]

Euclidean self-dual gravity: Ashtekar variables without gauge fixing

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Marc Basquens, Eduardo J. S. Villaseñor, , | Summary: The GNH method is used in this paper to study the Hamiltonian formulation of the Euclidean self-dual action. This action can be used to arrive at the complex Ashtekar formulation of General Relativity […]
