Cesaro Means along Polynomial Subsequences of Fourier Partial Sums at Lebesgue Points
Ushangi Goginava
In 1936, Zalcwasser proved the almost everywhere convergence of the arithmetic means of the square subsequence of trigonometric Fourier partial sums and asked whether this result e…
Calibration database design for the wide-field X-ray telescope on board the Einstein Probe
Huaqing Cheng, Hai-Wu Pan, Yuan Liu +6
The wide-field X-ray telescope (WXT) is the primary payload of the Einstein Probe (EP) mission. Utilizing innovative lobster-eye micro-pore optics (MPO), it achieves an unprecedent…
Onboard catalog of known X-ray sources for EP-WXT
He-Yang Liu, Haiwu Pan, Yuan Liu +14
The Einstein Probe (EP) is dedicated to explore the dynamic X-ray universe and capture transient events in real time with its Wide-field X-ray Telescope (WXT). However, WXT's unpre…
In-flight calibration of the Wide-field X-ray Telescope on board the Einstein Probe
Huaqing Cheng, Hai-Wu Pan, Yuan Liu +14
By utilizing novel lobster-eye optics, the Wide-field X-ray Telescope (WXT) onboard the Einstein Probe (EP) satellite achieves an unprecedented combination of a large instantaneous…
The effectively optically thin accretion flow and its implication in supermassive black holes
Mingjun Liu, B. F. Liu, Yilong Wang +2
Based on a unified description of various accretion flows, we find a long-ignored solution - the effectively optically thin accretion flow, occurring at accretion rates around Eddi…
In-flight calibration of the Lobster Eye Imager for Astronomy
Huaqing Cheng, Hai-Wu Pan, Yuan Liu +12
The Lobster Eye Imager for Astronomy (LEIA), as a pathfinder of the Wide-field X-ray Telescope (WXT) onboard the Einstein Probe (EP) satellite, is the first lobster-eye focusing X-…
