  This work explores whether gravitational waves (GWs) from neutron star (NS)
mountains can be detected with current 2nd-generation and future 3rd-generation
GW detectors. In particular, we focus on a scenario where transient mountains
are formed immediately after a NS glitch. In a glitch, a NS's spin frequency
abruptly increases and then often exponentially recovers back to, but never
quite reaches, the spin frequency prior to the glitch. If the recovery is
ascribed to an additional torque due to a transient mountain, we find that GWs
from that mountain are marginally-detectable with Advanced LIGO at design
sensitivity and is very likely to be detectable for 3rd-generation detectors
such as the Einstein Telescope. Using this model, we are able to find
analytical expressions for the GW amplitude and its duration in terms of
observables.
