Currently, Han's group has built a fully relativistic gravitational wave calculation model for asymmetric binary systems based on this new method, which is now the most precise and fastest fully relativistic waveform template. This template can be directly applied to data analysis for China's future space-based gravitational wave d...

Its retrograde nearly ecliptic orbit (i ≈ 175°) combined with a relatively small perihelion distance (q ≈ 1.36 AU) effectively directs the interloper "against traffic" through the densely populated regions of the inner Solar System. This significantly increases the probability of close encounters and potential interaction (inclu...

Recently, a research team led by the Tianma group, utilizing the Shanghai Tianma 65-meter telescope and Yebes 40-meter telescope, discovered that the turbulence caused by shear-motionof molecular clouds may be the dominant heating mechanism for molecular gas in the Galactic Center. This research was published in the Astrophysical J...
