WD-fTDEs background from dwarf galaxies (dark green line, left panel) and WD-fTDEs background from GCs (light green line, right panel). We assume that the mass of the intermediate-mass BH in each GC is 10³ M_⊙ and that the occupation fraction is equal to 1 for both scenarios. Both signals are plotted with respect to the sensitivity curves of LISA (blue line), DO (orange line), and μAres (black line).
