Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Megan Masterson, Erin Kara, Dheeraj R. Pasham, Daniel J. D’Orazio, Dominic J. Walton | Summary: The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence NICER X-ray monitoring with multiple visits per […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista, Min Du, Peter Erwin | Summary: From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass $log M_star > 10$ at $z=0$. We search for box/peanut bulges (BPs) in this sample, […]
