We observed the transits of six hot Jupiters with the Gran Telescopio de Canarias (GTC). The planets cover a large range of physical parameters such as planetary temperature, surface gravity, mass, radii and scale height. This broad range of physical parameters allowed us to characterize different hot-Jupiter atmospheres. The transits were observed

Correlations between the radio continuum, infrared, and CO emissions are known to exist for several types of galaxies and across several orders of magnitude. However, the low-mass, low-luminosity, and low-metallicity regime of these correlations is not well known. A sample of metal-rich and metal-poor dwarf galaxies from the literature has been

A wealth of tiny galactic systems populates the surroundings of the Milky Way. However, some of these objects might have originated as former satellites of the Magellanic Clouds, in particular of the Large Magellanic Cloud (LMC). Examples of the importance of understanding how many systems are genuine satellites of the Milky Way or the LMC are the

The detections of fullerenes and (possibly) planar C_{24} (a small fragment of a graphene sheet) in the H-rich circumstellar environments of evolved stars show that formation of these complex species does not require an H-poor environment contrary to general expectation. This together with the very recent identification of the fullerene cation C_

We report the results on the EMIR (Espectrógrafo Multiobjeto Infra-Rojo) performances after two semesters of scientific operations at the Gran Telescopio Canarias (GTC). 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

The study of high redshift galaxies is crucial for understanding the reionization process, the formation and evolution of galaxies, and the large-scale structure in the Universe. The main goal of this project was to obtain an ultra-deep image taken with a narrow-band filter (FWHM = 11nm and central wavelength λ_{c} = 1.254 μm), designed by the ALBA
