How do the properties of the neutral gas outflow, such as its velocity and kinetic energy, compare to those observed in other quenching galaxies?
The properties of the neutral gas outflow in the galaxy at a redshift of 2.445, as observed through JWST spectroscopy, exhibit significant differences compared to those seen in other quenching galaxies. The velocity of the neutral gas outflow in this galaxy is notably higher, indicating a more powerful ejection of gas. This high velocity suggests that the outflow is capable of efficiently removing a substantial amount of gas from the galaxy, thereby quenching star formation at a rapid pace. Additionally, the kinetic energy associated with this neutral gas outflow is also higher than what is typically observed in other quenching galaxies, further emphasizing the effectiveness of this mechanism in shutting down star formation.
