Resumen
In this article we study gravitational lensing by non-rotating and asymptotically flat black holes in Horndeski theory. By adopting the strong deflection limit, we calculate the deflection angle, from which we obtain the positions and the magnifications of the relativistic images. We compare our results with those corresponding to black holes in General Relativity. We analyze the astrophysical consequences in the case of the nearest supermassive black holes.<div id="extensionInstalled" style="display: none;"><div id="extensionInstalled" style="display: none;"><div id="extensionInstalled" style="display: none;" /></div><div id="extensionInstalled" style="display: none;"><div id="extensionInstalled" style="display: none;"><div id="extensionInstalled" style="display: none;" /></div></div><div id="extensionInstalled" style="display: none;"><div id="extensionInstalled" style="display: none;"><div id="extensionInstalled" style="display: none;"></div></div></div></div><div id="extensionInstalled" style="display: none;" /><div id="extensionInstalled" style="display: none;" /><div id="extensionInstalled" style="display: none;" />
