FPU22/03222Dark matter may not be perfectly stable, and its decay could generate distinctive gravitational-wave signatures. In this work, we present model-independent predictions for the stochastic gravitational-wave background arising from the decay of ultralight dark matter into gravitons. Within this framework, we forecast the sensitivity reach of current and forthcoming gravitational-wave detectors to such signals.engjournal article1475-7516https://doi.org/10.1088/1475-7516/2026/03/055https://iopscience.iop.org/article/10.1088/1475-7516/2026/03/055https://arxiv.org/abs/2510.18958embargoed access524.8530.12530.122.1Materia oscuraOndas gravitacionalesDark matterGravitational wavesFísica (Física)2212.07 Gravitones2212.99 Otras2212.14 Teoría de la Relatividad2101 Cosmología y Cosmogonía
