An X-ray Absorption-Line Survey of the Circumgalactic Medium of M31 with XMM-Newton

Kaile Wang, Zheng Zhou, Taotao Fang +1

X-ray absorption line spectroscopy provides a powerful method for probing the extended hot circumgalactic medium (CGM) of individual galaxies. In this study, we present the first s…

Constraining the Milky Way's Dispersion Measure Using FRB and X-ray Data

Jiale Wang, Zheng Zhou, Xiaochuan Jiang +1

The dispersion measures (DMs) of fast radio bursts (FRBs) are a valuable tool for probing the baryonic content of the intergalactic and the circumgalactic medium of the intervening…

Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): Dynamical Evidence of a Spiral-Arm-Driving and Gap-Opening Protoplanet from SAO 206462 Spiral Motion

Chen Xie, Chengyan Xie, Bin B. Ren +8

In the early stages of planetary system formation, young exoplanets gravitationally interact with their surrounding environments and leave observable signatures on protoplanetary d…
