EP260321a/SN 2026gzf: The Faintest Shock Breakout Associated with a Broad-Lined Supernova
Brendan O'Connor, Xander J. Hall, Malte Busmann +33
The explosion of a star is first marked by the shock wave breaking out of the stellar surface, producing a burst of ultraviolet and X-ray radiation. These events are observationall…
Dust-Obscured Galaxies in the XMM-SERVS Fields: Selection, Multiwavelength Characterization, and Physical Nature
Zhibo Yu, W. N. Brandt, Fan Zou +7
Dust-obscured galaxies (DOGs) are enshrouded by dust, and many are believed to host accreting supermassive black holes (SMBHs), which makes them unique objects for probing the coev…
The bicoherence analysis of type C quasi-periodic oscillations in Swift J1727.8-1613
Haifan Zhu, Wei Wang, Ziyuan Zhu
We present the results of bicoherence analysis for Swift J1727.8-1613 during its 2023 outburst, using data from Insight-HXMT. Our analysis focused on observations with quasi-period…
The bicoherence study of quasi-periodic oscillations in MAXI J1535-571
Ziyuan Zhu, Xiao Chen, Wei Wang
Bicoherence is a way to measure the phase coupling of triplets of Fourier frequencies. We use this method to analyze quasi-periodic oscillations (QPOs) in the black hole X-ray bina…
