Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole

Posted by dbos January 3, 2025MIT

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Erin Kara, Christos Panagiotou, William N. Alston, Joheen Chakraborty | Summary: Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the newly-discovered quasi-periodic eruptions (QPEs), […]

FEASTS: Radial Distribution of HI surface densities down to 0.01 M$_{odot}$ pc$^{-2}$ of 35 Nearby Galaxies

Posted by dbos January 2, 2025January 13, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Dong Yang, Xuchen Lin, Qifeng Huang, Zhijie Qu | Summary: We present the HI surface density ($Sigma_{rm HI}$) radial distributions based on total-power HI images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72 degree. We derive the HI […]

Heitler effect and resonance fluorescence in quantum magnonics

Posted by dbos January 2, 2025January 13, 2025Delft

Kavli Affiliate: Ya M. Blanter | First 5 Authors: Enes Ilbuğa, V. V. Dobrovitski, Ya. M. Blanter, , | Summary: We consider a coupled system of a qubit and a magnon mode in which the qubit is weakly driven. We demonstrate that the spectral steady-state responses of both the qubit and the magnon show, in […]
