The 3D structure and extinction law are studied for the Taurus, Orion, Perseus and California molecular clouds (MCs) based on the LAMOST and APOGEE spectroscopy. Extinctions are calculated from color excess derived from the Blue Edge methods. In combination with the distance from the Gaia, a 3D extinction map and the structure of these MCs can be retrieved and the clouds that overlap in the sk...
Bent radio AGN, with their classic “C” shaped morphology, are a unique class of radio AGNs. These radio sources are often used as signposts of a dense, gaseous medium, such as the intracluster medium (ICM). However, bent sources are found inside and outside cluster environments, raising the question of how environment impacts bent radio AGN morphology. We analyzed new LOw-Frequency Array Two-...

In the past decade, Galactic Chemical Evolution (GCE) has flourished due to surveys like Gaia, LAMOST, and Galex, which have enabled detailed investigations of stellar abundances. Stellar nucleosynthesis has also made strides in calculating both stable and radioactive isotopes, including the heavy isotopes produced by rapid neutron-capture (r-process). However, the astrophysical sources of r-p...
General relativity is currently the standard theory to describe gravity. It has passed all the tests in our Solar System and has been positively supported by astronomy observations including electromagnetic waves from neutron stars and gravitational waves from coalescing compact binary systems. But fundamentally it is incompatible with quantum theory, and there are also the large-scale observat...
