Brown dwarf number density in the JWST COSMOS-Web field
Amos Y. -A. Chen, Tomotsugu Goto, Cossas K. -W. Wu +9
Brown dwarfs are failed stars with very low mass (13 to 75 ), and an effective temperature lower than 2500 K. Thus, they play a key role in understanding the gap in the mass f…

Decoding the cosmological baryonic fluctuations using localized fast radio bursts
Tzu-Yin Hsu, Tetsuya Hashimoto, Tsung-Ching Yang +7
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…

Constraining the Hubble constant with scattering in host galaxies of fast radio bursts
Tsung-Ching Yang, Tetsuya Hashimoto, Tzu-Yin Hsu +5
Measuring the Hubble constant (H) is one of the most important missions in astronomy. Nevertheless, recent studies exhibit differences between the employed methods. Fast radio…
