  abstract     = {{  We present a high-resolution view of bubbles within The Phantom Galaxy (NGC
628); a nearby (~10Mpc), star-forming (~2Msun/yr), face-on (i~9deg)
grand-design spiral galaxy. With new data obtained as part of the PHANGS-JWST
treasury program, we perform a detailed case-study of two regions of interest,
one of which contains the largest and most prominent bubble in the galaxy (The
Phantom Void; over 1kpc in diameter), and the other being a smaller region that
may be the precursor to such a large bubble (The Precursor Phantom Void). When
comparing to matched resolution Halpha observations from the Hubble Space
Telescope (HST), we see that the ionized gas is brightest in the shells of both
bubbles, and is coincident with the youngest (~1Myr) and most massive
(~100,000Msun) stellar associations. We also find an older generation (~20Myr)
of stellar associations is present within the bubble of The Phantom Void. From
our kinematic analysis of the HI, H2 (CO) and HII gas across The Phantom Void,
we infer a high expansion speed of around 15 to 50km/s. The large size and high
expansion speed of The Phantom Void suggest that the driving mechanism is
sustained stellar feedback due to multiple mechanisms, where early feedback
first cleared a bubble (as we observe now in The Precursor Phantom Void), and
since then SNe have been exploding within the cavity, and have accelerated the
shell. Finally, comparison to simulations shows a striking resemblance to our
JWST observations, and suggests that such large-scale stellar feedback-driven
bubbles should be common within other galaxies.
