We study the prospect of simultaneous explanation of tiny neutrino masses,dark matter (DM), and the observed baryon asymmetry of the Universe in a$Z_3$-symmetric complex singlet scalar extended type-II seesaw model. Thecomplex singlet scalar plays the role of DM. Analyzing the thermal history ofthe model, we identify the region of the parameter space that can generate afirst-order electroweak phase transition (FOEWPT) in the early Universe, andthe resulting stochastic gravitational waves (GW) can be detected at futurespace/ground-based GW experiments. First, we find that light triplet scalars dofavor an FOEWPT. In our study, we choose the type-II seesaw part of theparameter space in such a way that light triplet scalars, especially the doublycharged ones, evade the strong bounds from their canonical searches at theLarge Hadron Collider (LHC). However, the relevant part of the parameter space,where FOEWPT can happen only due to strong SM doublet-triplet interactions, isin tension with the SM-like Higgs decay to a pair of photons, which has alreadyexcluded the bulk of this parameter space. On the other hand, the latestspin-independent DM direct detection constraints from XENON-1T and PANDA-4Teliminate a significant amount of parameter space relevant for the dark sectorassisted FOEWPT scenarios, and it is only possible when the complex scalar DMis significantly underabundant. In short, we conclude from our analysis thatthe absence of new physics at the HL-LHC and/or various DM experiments in thenear future will severely limit the prospects of detecting a stochastic GW atfuture GW experiments and will exclude the possibility of electroweakbaryogenesis within this model.
