Dynamically driven collapse of a thermally stable accretion disk in a nova-like system
Wentao Li, Jie Lin, Tinggui Wang +8
While standard disk instability theory predicts thermal-steady, outburst-free disks in nova-like variables due to their high mass transfer rates, mass transfer variations are preva…
Discovery of a Featureless Tidal Disruption Event at z~1 with the Wide Field Survey Telescope
Jiazheng Zhu, Zelin Xu, Ning Jiang +31
We report the discovery of tidal disruption event (TDE) WFST250820mmsw/AT2025wet by the 2.5-meter Wide Field Survey Telescope (WFST). It exhibits a blue nuclear flare throughout th…
The Redshift Difference in Gravitational Lensed Systems: A Novel Probe of Cosmology
Chengyi Wang, Krzysztof Bolejko, Geraint F. Lewis
The exploration of the redshift drift, a direct measurement of cosmological expansion, is expected to take several decades of observation with stable, sensitive instruments. We int…
The Instantaneous Redshift Difference of Gravitationally Lensed Images: Theory and Observational Prospects
Chengyi Wang, Krzysztof Bolejko, Geraint F. Lewis
Due to the expansion of our Universe, the redshift of distant objects changes with time. Although the amplitude of this redshift drift is small, it will be measurable with a decade…
Direct detection of the cosmic expansion: the redshift drift and the flux drift
Krzysztof Bolejko, Chengyi Wang, Geraint F. Lewis
The redshift drift, the change of cosmological redshift with time, is a direct consequence of the expansion of the Universe. Thus the measurement of the cosmological redshift drift…
