A Case for a Binary Black Hole System Revealed via Quasi-Periodic Outflows

Kavli Affiliate: Erin Kara | First 5 Authors: Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova, Michal Zajacek, Suvendu Rakshit | Summary: Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in X-ray absorption […]

Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek, Itai Linial, Petra Sukova | Summary: Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underlying physical mechanism is a […]

Lense-Thirring Precession after a Supermassive Black Hole Disrupts a Star

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Michal Zajacek, C. J. Nixon, Eric R. Coughlin, Marzena Sniegowska | Summary: An accretion disk formed around a supermassive black hole (SMBH) after it disrupts a star is expected to be initially misaligned with respect to the black hole’s equatorial plane. This misalignment […]

Pheromone representation in the ant antennal lobe changes with age

Kavli Affiliate: Daniel Kronauer | Authors: Taylor Hart, Lindsey E. Lopes, Dominic D. Frank and Daniel J.C. Kronauer | Summary: While the neural basis of age-related decline has been extensively studied (1–3), less is known about changes in neural function during the pre-senescent stages of adulthood. Adult neural plasticity is likely a key factor in […]

A pulsar-like swing in the polarisation position angle of a nearby fast radio burst

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ryan Mckinven, Mohit Bhardwaj, Tarraneh Eftekhari, Charles D. Kilpatrick, Aida Kirichenko | Summary: Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals bear similarities with the much less luminous radio […]
