Pulsar timing array detections of supermassive binary black holes: implications from the detected common process signal and beyond

Posted by dbos Peking

Kavli Affiliate: Qingjuan Yu | First 5 Authors: Yunfeng Chen, Qingjuan Yu, Youjun Lu, , | Summary: Pulsar timing arrays (PTAs) are anticipated to detect the stochastic gravitational wave background (GWB) from supermassive binary black holes (BBHs) as well as the gravitational waves from individual BBHs. Recently, a common process signal was reported by several […]

The correlations of stellar tidal disruption rates with properties of massive black holes and their host galaxies

Posted by dbos Peking

Kavli Affiliate: Qingjuan Yu | First 5 Authors: Yunfeng Chen, Qingjuan Yu, Youjun Lu, , | Summary: Stars can be either disrupted as tidal disruption events (TDEs) or swallowed as a whole by massive black holes (MBHs) at galactic centers when they approach sufficiently close to these MBHs. In this work, we investigate the correlations […]

Discovery of strongly variable X-ray polarization in the neutron star low-mass X-ray binary transient XTE J1701$-$462

Posted by klaurent Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Massimo Cocchi, Andrea Gnarini, Sergio Fabiani, Francesco Ursini, Juri Poutanen | Summary: After about 16 years since its first outburst, the transient neutron star low-mass X-ray binary XTE J1701$-$462 turned on again in September 2022, allowing for the first study of its X-ray polarimetric characteristics by […]

WiCo: Win-win Cooperation of Bottom-up and Top-down Referring Image Segmentation

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Zesen Cheng, Peng Jin, Hao Li, Kehan Li, Siheng Li | Summary: The top-down and bottom-up methods are two mainstreams of referring segmentation, while both methods have their own intrinsic weaknesses. Top-down methods are chiefly disturbed by Polar Negative (PN) errors owing to the lack of fine-grained […]

Frequency Modulation of Gravitational Waves by Ultralight Scalar Dark Matter

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: The oscillating pressure of the ultralight scalar dark matter (DM) can induce the oscillation of the local gravitational potential. Similar to the time-dependent frequency shift for the pulse signals of pulsars, the oscillation of the local gravitational potential can induce […]

AdaSelection: Accelerating Deep Learning Training through Data Subsampling

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Minghe Zhang, Chaosheng Dong, Jinmiao Fu, Tianchen Zhou, Jia Liang | Summary: In this paper, we introduce AdaSelection, an adaptive sub-sampling method to identify the most informative sub-samples within each minibatch to speed up the training of large-scale deep learning models without sacrificing model performance. Our method […]
