En las últimas dos décadas, nuestro conocimiento de los cúmulos estelares jóvenes, ha progresado rápidamente del uso de imágenes estáticas con cada vez mayor calidad, hacia mapas de movimientos en seis dimensiones (posiciones, velocidades), que están cambiando muchas de nuestras ideas de cómo los

As the birth-sites of planets, protoplanetary discs have become the object of intense study during the last years. Constraining their typical lifetimes, masses and/or sizes is crucial to understand the process of planet formation.

We present a theoretical model in order to explain the formation and the evolution of the molecular outflows associated to protostars.

Molecular observations at high resolution is being revolutionized by the success of ALMA and the upcoming advent of SKA.

JPAS is a survey of 5000-8000 deg2 of the sky with 56 narrow band filters in the Observatory of Javalabre. This survey is very relevant for Cosmology, Galaxy Evolution and Stellar Physics studies. In January 2020, JPAS with its JPCam will have the first light.

The upper atmosphere of a planet plays a key role at protecting the lower altitudes from the effects of energetic stellar EUV and soft X-ray photons and keV-energy precipitating particles.

Characterization of planetary atmospheres has always been a challenge. While the next generation of facilities, such as ELT, JWST, and ARIEL, will improve our understanding of planetary atmospheres, the number of well-characterized exoplanet atmospheres is expected to remain limited.

Cranfield Precision are not specialists in astronomy but their expertise in designing and building very precise special-purpose machines has contributed to several important astronomical projects.

This talk presents a way to find Type I Active Galactic Nuclei in the MaNGA survey (Mapping Nerby Galaxies at Apache point observatory). The method is based on flux ratios between spectral regions where a broad line in emission is expected.

Cool dwarfs are the most numerous stars in the Galaxy and they account for most of its baryonic mass. However, they are likely the least understood main sequence stars.

Planetesimals and small solid bodies in general  are key to understand the chemical and dynamical evolution of planetary systems. Direct detection outside the Solar System is still not feasible.

The supernova SN1987A in the Large Magellanic Cloud, together with new instrumentation like ALMA, offers an unprecedented opportunity to tackle fundamental issues of supernova explosions. Large masses of molecules and dust have been formed in its inner debris over the last 25 years.

In this talk I will present highlights from our recent work  about the analysis of high-resolution (R ~ 20 000) GTC/MEGARA integral-field unit spectroscopic observations, obtained during the commissioning run, in the inner region (12.5arcsec×11.3arcsec) of the active galaxy NGC7469, at spatial sc

Young low-mass galaxies with extreme emission-line properties are ubiquitous at high redshift and they are believed to play a key role in cosmic reionisation and the early growth of galaxies at z>4-6.

Galactic outflows are an essential component of galaxies' lifecycle. They regulate star formation and can even totally quench star formation in galaxies, hence transforming star forming galaxies into passive systems.

The dust component of active galactic nuclei (AGN) produces a broad infrared spectral energy distribution (SED), whose power and shape depends on the fraction of the source absorbed, and the geometry of the absorber respectively.

METIS is one of the three first instruments for the European Extremely Large Telescope (ELT), Europe’s next-generation ground-based telescope for optical and infrared wavelengths which is currently under construction at the ESO site at Cerro Armazones in Chile.

FPGAs are key components in space equipment due to their versatility and performance to implement digital functions.

Feedback originated from star formation and AGN activity in galaxies can have a significant impact on their evolution.

During the last decades, many authors have put large efforts to shed light on the mechanisms responsible of the generalized growth in size of galaxies, as well as to disentangle the main “driver” of their stellar content.

Line diagnostics is very important to understand the physics of astronomical sources.

The Square Kilometre Array (SKA) project is an international effort to build the largest radio telescope on Earth, which will be able to make revolutionary contributions to Astrophysics, Astrobiology and Fundamental Physics.

The discovery of collimated outflows in planetary nebulae (PNe) has changed the paradigm of PN formation. They actively participate in the nebular shaping immediately before or while fast stellar winds and D-type ionization fronts shock and swept the nebular envelope.

A growing number of studies report linkages between unrelated stratospheric and upper atmospheric phenomena. For example, stratospheric warmings correlate with ionospheric perturbations, and with reductions in polar mesospheric cloud occurrence.

One of the problems we are facing in the study of evolved low- and intermediate-mass stars such as Planetary Nebulae (PNe) is the lack of completeness. Most known PNe belong to the bright or intermediate part of the luminosity function, leaving out those at the faint end.

Orion is the massive star formation region closest to the Sun and in consequence it has been studied in detail. I will present three recent results from the IRyA group on this region.
