To this end, we consider acceleration radiation of a freely falling atom close to a Schwarzschild black hole (BH) in the presence of dark energy characterized by a positive cosmological constant $\\Lambda$. The resulting spacetime is endowed with a BH and a cosmological (or de Sitter) horizon. Our consideration is a \\textit{nonextremal} $(1+1)$-dimensional geometry with horizons far apart, giving rise to a flat Minkowski-like region in between the two horizons.
