<p>MEGARA is the new optical spectrograph of GTC. Once installed at GTC (spring of 2017) it will offer Integral-Field and Multi-object spectroscopic capabilities in the entire optical window (370-970nm) with resolutions in the range R=6000-20000. In this talk I will summarize the main characteristics of the instrument with special emphasis to its potential applications to the study of the nuclear regions of galaxies both locally (the IFU covers 12.5x11.3 arcsec^2 with spaxels of 0.62 arcsec) and at high-redshift (92x Fiber-MOS robotic positioners equipped with 7-fiber mini-IFUs).</p
