We performed a multiwavelength study towards the infrared dark cloud(IRDC) G31.23+0.05 with new CO observations from Purple Mountain Observatory and archival da
The neutrino burst detected during supernova SN 1987A is explained in a strangeon star model, in which it is proposed that a pulsar-like compact object is compo
We present observations of the eruption of a large-scale quiescent filament(LF) that is associated with the formation and eruption of a miniature filament(MF).
How supermassive black holes(SMBHs) are spun-up is a key issue in modern astrophysics. As an extension to the study in Wang et al., here we address the issue by
