Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303

Posted by dbos February 24, 2023MIT

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 […]

Determining Molecular Complexity using Assembly Theory and Spectroscopy

Posted by klaurent February 24, 2023Stanford

Kavli Affiliate: Stuart Marshall | Summary:Determining the complexity of molecules has important applications from molecular design to understanding the history of the process that led to the formation of the molecule. Currently, it is not possible to experimentally determine, without full structure elucidation, how complex a molecule is. Assembly Theory has been developed to quantify […]

A Fiber-coupled Scanning Magnetometer with Nitrogen-Vacancy Spins in a Diamond Nanobeam

Posted by dbos February 24, 2023Delft

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Yufan Li, Fabian A. Gerritsma, Samer Kurdi, Nina Codreanu, Simon Gröblacher | Summary: Magnetic imaging with nitrogen-vacancy (NV) spins in diamond is becoming an established tool for studying nanoscale physics in condensed matter systems. However, the optical access required for NV spin readout remains an […]

A new twist on PIFE: photoisomerisation-related fluorescence enhancement

Posted by klaurent February 24, 2023Oxford

Kavli Affiliate: Achillefs Kapanidis | Summary:PIFE was first used as an acronym for protein-induced fluorescence enhancement, which refers to the increase in fluorescence observed upon the interaction of a fluorophore, such as a cyanine, with a protein. This fluorescence enhancement is due to changes in the rate of cis/trans photoisomerisation. It is clear now that […]
