A LOFAR Look at Bent Double Lobed Radio Sources: Probing Differences in the Properties of Bent Radio AGNs Inside and Outside of High-z Galaxy Clusters
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-...

The Evolution of All Stable Isotopes within Galaxies Across Cosmic Time
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...

Alternative theories of gravity and their tests using astronomy observations
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...

A fast radio burst source at a complex magnetized site in a barred galaxy
Fast radio bursts (FRBs) are highly dispersed, millisecond-duration radio bursts prevailing in the universe. Recent observations of a Galactic FRB suggest that at least some FRBs originate from magnetars, but it is unclear whether the majority of cosmological FRBs, especially the actively repeating ones, are produced from the magnetar channel. Until now, more than 800 FRBs have been detected by...
