Query: Sunspot Light Walls Suppressed by Nearby Brightenings   Light walls, as ensembles of oscillating bright structures rooted in sunspot
light bridges, have not been well studied, although they are important for
understanding sunspot properties. Using the Interface Region Imaging
Spectrograph and Solar Dynamics Observatory observations, here we study the
evolution of two oscillating light walls each within its own active region
(AR). The emission of each light wall decays greatly after the appearance of
adjacent brightenings. For the first light wall, rooted within AR 12565, the
average height, amplitude, and oscillation period significantly decrease from
3.5 Mm, 1.7 Mm, and 8.5 min to 1.6 Mm, 0.4 Mm, and 3.0 min, respectively. For
the second light wall, rooted within AR 12597, the mean height, amplitude, and
oscillation period of the light wall decrease from 2.1 Mm, 0.5 Mm, and 3.0 min
to 1.5 Mm, 0.2 Mm, and 2.1 min, respectively. Particularly, a part of the
second light wall becomes even invisible after the influence of nearby
brightening. These results reveal that the light walls are suppressed by nearby
brightenings. Considering the complex magnetic topology in light bridges, we
conjecture that the fading of light walls may be caused by a drop in the
magnetic pressure, where flux is cancelled by magnetic reconnection at the site
of the nearby brightening. Another hypothesis is that the wall fading is due to
the suppression of driver source (p-mode oscillation), resulting from the
nearby avalanche of downward particles along reconnected brightening loops.
