X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary

Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]

Full parity phase diagram of a proximitized nanowire island

Kavli Affiliate: L. P. Kouwenhoven | First 5 Authors: J. Shen, G. W. Winkler, F. Borsoi, S. Heedt, V. Levajac | Summary: We measure the charge periodicity of Coulomb blockade conductance oscillations of a hybrid InSb-Al island as a function of gate voltage and parallel magnetic field. The periodicity changes from $2e$ to $1e$ at […]

Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies

Kavli Affiliate: Erin Kara | First 5 Authors: Michael McDonald, Brian R. McNamara, Michael S. Calzadilla, Chien-Ting Chen, Massimo Gaspari | Summary: We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live at the centers of […]
