http://research.iac.es/proyecto/emir/ {EMIR} is one of the first common user instruments for the GTC, the 10 meter telescope operating at the Roque de los Muchachos Observatory (La Palma, Canary Islands, Spain). EMIR has been built by a Consortium of Spanish and French institutes led by the Instituto de Astrofísica de Canarias (IAC). The instrument

The superb depth of present ultradeep observations and next generation synoptic surveys allow us to reach sudden decrements of the galaxy surface brightness in their outer parts. These truncations are intimately linked with the expected location of the cold gas density threshold for star formation. The unexpected existence of these limits in the

The discovery potential from astronomical and other data is limited by their noise. We introduce a novel non-parametric noise reduction technique based on Bayesian inference, \fabada, that automatically improves the signal-to-noise ratio of one- and two-dimensional data, such as astronomical images and spectra. The algorithm iteratively evaluates

Detecting the first galaxies of the Universe has always been a goal in extragalactic astronomy because the study of these sources provides important constraints on cosmic reionization. In Cabello et al. 2022, we exploited the capabilities of the 10.4 m Gran Telescopio Canarias (GTC) to carry out the narrow-band (NB) Ly$\alpha$ survey at the highest

The Carina Nebula complex consists of several stellar groups, some bound and some not, immersed in the Car OB1 association, a unique region to study Galactic massive stars. Containing a large number of O-stars, it is the most massive star-forming region within 3 kpc of the Sun. Even though the Carina Nebula harbors hundreds of massive stars, there

Mentoring programs for career and personal development have shown to be incredibly beneficial for mentees, boosting their work and life satisfaction. Mentoring programs are particularly important for women in academia, where they are usually a minority. In 2021, in the context of the commission of Women in Astronomy of the Spanish Society of
