dc.description.abstractWe discuss the broad-band X-ray spectrum of GRS 1734−292 obtained from non-simultaneous XMM–Newton and NuSTAR (Nuclear Spectroscopic Telescope Array) observations, performed in 2009 and 2014, respectively. GRS1734−292 is a Seyfert 1 galaxy, located near the Galactic plane at z = 0.0214. The NuSTAR spectrum (3–80 keV) is dominated by a primary power-law continuum with Γ = 1.65 ± 0.05 and a high-energy cut-off Ec=53+11−8 keV, one of the lowest measured by NuSTAR in a Seyfert galaxy. Comptonization models show a temperature of the coronal plasma of kTe=11.9+1.2−0.9 keV and an optical depth, assuming a slab geometry, τ=2.98+0.16−0.19 or a similar temperature and τ=6.7+0.3−0.4 assuming a spherical geometry. The 2009 XMM–Newton spectrum is well described by a flatter intrinsic continuum (⁠Γ=1.47+0.07−0.03⁠) and one absorption line due to Fe XXV Kα produced by a warm absorber. Both data sets show a modest iron Kα emission line at 6.4 keV and the associated Compton reflection, due to reprocessing from neutral circumnuclear material.
