Decoding the cosmological baryonic fluctuations using localized fast radio bursts Open
Aims. The enigma of the missing baryons poses a prominent and unresolved problem in astronomy. Dispersion measures (DM) serve as a distinctive observable of fast radio bursts (FRBs). They quantify the electron column density along each lin…

Revisiting the Mysterious Origin of FRB 20121102A with Machine-learning Classification Open
Fast radio bursts (FRBs) are millisecond-duration radio waves from the Universe. Even though more than 50 physical models have been proposed, the origin and physical mechanism of FRB emissions are still unknown. The classification of FRBs …

Finding dusty AGNs from the <i>JWST</i> CEERS survey with mid-infrared photometry Open
The nature of the interaction between active galactic nuclei (AGNs) and their host galaxies remains an unsolved question. Therefore, conducting an AGN census is valuable for AGN research. Nevertheless, a significant fraction of AGNs are ob…

Polycyclic aromatic hydrocarbon (PAH) luminous galaxies in JWST CEERS data Open
It has been an unanswered question how many dusty galaxies have been undetected from the state-of-the-art observational surveys. JWST enables us to detect faint IR galaxies that have prominent polycyclic aromatic hydrocarbon (PAH) features…

Machine Learning Classification of Repeating FRBs from FRB121102 Open
Fast Radio Bursts (FRBs) are mysterious bursts in the millisecond timescale at radio wavelengths. Currently, there is little understanding about the classification of repeating FRBs, based on difference in physics, which is of great import…

Classifying a frequently repeating fast radio burst, FRB 20201124A, with unsupervised machine learning Open
Fast radio bursts (FRBs) are astronomical transients with millisecond timescales. Although most of the FRBs are not observed to repeat, a few of them are detected to repeat more than hundreds of times. There exist a large variety of physic…

Constraining the Hubble constant and its lower limit from the proper motion of extragalactic radio jets Open
The Hubble constant ($H_{0}$) is a measurement to describe the expansion rate of the Universe in the current era. However, there is a $4.4σ$ discrepancy between the measurements from the early Universe and the late Universe. In this resear…
