| Summary:

Macroscopic dark matter (or macro) provides a broad class of alternative
candidates to particle dark matter. These candidates would transfer energy
primarily through elastic scattering, and this linear energy deposition would
produce observable signals if a macro were to traverse the atmosphere. We study
the fluorescence emission produced by a macro passing through the atmosphere.
We estimate the sensitivity of EUSO-SPB2 to constrain the two-dimensional
parameter space ($sigma$ vs. $M$), where $M$ is the macro mass and $sigma$
its cross sectional area.
