Unsupervised Deep Learning Method for Clustering KAGRA O3GK Transient Noise Data
Yubin Kim, Kihyun Jung, Kyujin Kwak
The advent of ground-based gravitational wave detectors has significantly improved the detection of faint gravitational wave signals. However, these detectors are affected by vario…
The compact neutron star in 4U 1746-37 revisited: Reassessing the mass and radius
Kwang Hyun Sung, Myungkuk Kim, Young-Min Kim +2
A recent analysis of photospheric radius expansion X-ray bursts from the low-mass X-ray binary 4U 1746-37 reported unusually small mass and radius estimates for the neutron star, s…
Neutrinos from Carbon-Burning Red Supergiants and Their Detectability
Gwangeon Seong, Kyujin Kwak, Dongsu Ryu +1
Stars emit MeV neutrinos during their evolution via nuclear syntheses and thermal processes, and detecting them could provide insights into stellar structure beyond what is accessi…
12C+12C Reaction Rates and the Evolution of a Massive Star
Gwangeon Seong, Yubin Kim, Kyujin Kwak +4
Carbon fusion is important to understand the late stages in the evolution of a massive star. Astronomically interesting energy ranges for the 12C+12C reactions have been, however,…
