Messy Eaters: A Diversity of Supermassive Black Hole Accretion Behaviors Revealed By Nuclear Transients
Abstract:
Optical transient surveys have ushered in the golden era of time-domain astronomy and exposed an unexpected breadth of transient phenomena, including nuclear transients: flares powered by accretion onto supermassive black holes (SMBHs). These transients provide a means to identify and study otherwise quiescent SMBHs across a range of masses and redshifts. In this talk, I will discuss the physics underpinning these transients, the role of the surrounding nuclear environment in setting their observable signatures, and their utility as probes of SMBHs. I will highlight my contributions from studies of the major classes of nuclear transients through case studies of well-observed individual objects — all discovered by UH-affiliated surveys —and population studies to investigate trends. I will conclude with a look towards the future of nuclear transients in the era of deep surveys like LSST and Roman.
