Description
On June 25th 2017, the new intermediate-resolution optical IFU and MOS
of the 10.4-m GTC had its first light. As part of the tests carried out
to verify the performance of the instrument in its two modes (IFU and
MOS) and 18 spectral setups (identical number of VPHs with resolutions
R=6000-20000 from 0.36 to 1 micron) a number of astronomical objects
were observed. These observations show that MEGARA@GTC is called to fill
a niche of high-throughput, intermediateresolution IFU and MOS
observations of extremely-faint narrow-lined objects. Lyman-α
absorbers, star-forming dwarfs or even weak absorptions in stellar
spectra in our Galaxy or in the Local Group can now be explored to a new
level. Thus, the versatility of MEGARA in terms of observing modes and
spectral resolution and coverage will allow GTC to go beyond current
observational limits in either depth or precision for all these objects.
The results to be presented in this talk clearly demonstrate the
potential of MEGARA in this regard.

Starbursts in Galaxies GEFE
Starsbursts play a key role in the cosmic evolution of galaxies, and thus in the star formation (SF) history of the universe, the production of metals, and the feedback coupling galaxies with the cosmic web. Extreme SF conditions prevail early on during the formation of the first stars and galaxies, therefore, the starburst phenomenon constitutes a
Physical properties and evolution of Massive Stars
This project aims at the searching, observation and analysis of massive stars in nearby galaxies to provide a solid empirical ground to understand their physical properties as a function of those key parameters that gobern their evolution (i.e. mass, spin, metallicity, mass loss, and binary interaction). Massive stars are central objects to
