Interacting Binary Stars as Progenitors for Interacting Supernovae
Sung-Han Tsai, Ke-Jung Chen, Keiichi Maeda +2
Dense, compact circumstellar media (CSM) are required to power strongly interacting supernovae, yet their physical origin remains uncertain. We present a systematic study of binary…

Origins of Supermassive Black Holes in Galactic Centers
Ke-Jung Chen
Direct imaging of black hole shadow halos has firmly confirmed the existence of supermassive black holes (SMBHs), with millions of solar masses, residing at the centers of the Milk…

Inferring Dense Confined Circumstellar Medium around Supernova Progenitors via Long-term Hydrodynamical Evolution
Tomoki Matsuoka, Keiichi Maeda, Ke-Jung Chen
Circumstellar interaction of supernova (SN) ejecta is an essential process in its evolution and observations of SNe have found the signature of circumstellar interaction both in th…
