Imaging-spectroscopy diagnosis of the giant sloshing spiral in the Virgo cluster with the Einstein Probe Follow-up X-ray Telescope
X. Zheng, S. Jia, C. Li +46
We performed deep X-ray observations of the Virgo cluster using the Einstein Probe Follow-up X-ray Telescope (EP-FXT) with a total exposure of 295 ks. Leveraging the large field of…
Einstein Probe discovery of the short period intermediate polar EP J115415.8-501810
Y. Xiao, M. Ge, N. Rea +21
The X-ray transient source EP240309a/EP\,J115415.8501810 was first detected by the Wide-Field X-ray Telescope (WXT) on board Einstein Probe (EP) during the commissioning phase.…
A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
An Intermediate-mass Black Hole Lurking in A Galactic Halo Caught Alive during Outburst
C. -C. Jin, D. -Y. Li, N. Jiang +137
Stellar-mass and supermassive black holes abound in the Universe, whereas intermediate-mass black holes (IMBHs) of ~10^2-10^5 solar masses in between are largely missing observatio…
Broad-band X-ray spectral and timing properties of the accreting millisecond X-ray pulsar IGR J174982921 during the 2023 outburst
Zhaosheng Li, L. Kuiper, Y. Y. Pan +10
We report on the broadband spectral and timing properties of the accreting millisecond X-ray pulsar IGR J174982921 during its April 2023 outburst using data from NICER (110 k…
