MeerKAT is a radio telescope situated in South Africa's Karoo desert. It has recently been built as an SKA demonstrator and precursor telescope and was inaugurated in August 2018.

MAAT (Mirror-slicer Array for Astronomical Transients) is proposed as a new mirror-slicer optical system that will allow the OSIRIS spectrograph at the 10.4 m GTC the capability to perform integral-field spectroscopy (IFS) over a seeing-limited field of view 14.20’' x 10'' with a slice width of 0

I will present the generalities of the Gaia surveying mission, and current status.  I will then discuss the improvement brought by Gaia over its 5 years and more of mission—starting with DR1—for the science of asteroids and other SSOs; and focusing especially on the astrometry and dynamics of ast

The burgeoning field of exoplanets has yielded thousands of discoveries, which collectively have the potential to help us better understand our place in the Universe.

Protostars accrete their material from the natal cloud through accretion disks. These disks are progressively dispersed by the recently formed star to form protoplanetary discs in which planets are born.

The hunt for Gamma-Ray-Bursts (GRBs) at very high energy (VHE) started more than 20 years ago. A hint of emission was already claimed by Milagrito from the observations of GRB 970417.

Extragalactic surveys in the 2020s will reveal the full diversity of the galaxy assembly process: from environment-dependent evolution to the build-up of mass inside galaxies, and with a complete accounting of all relevant processes/constituents ensured by multi-wavelength coverage.

The Calar Alto observatory (CAHA) is a key institution for the international astronomical community, for its highly competitive astronomical facilities (telescopes and instrumentation).

Recently a group of scientists has confirmed the presence of water in the atmosphere of a super Earth orbiting in the habitable zone of its host star. But what what does this milestone represent in the search for life outside Earth? What do we mean by habitable?

Nebular HeII1640,4686 emission, observed to be more frequent in high-z galaxies than locally, is indicative of far harder ionizing spectrum than that seen in nearby systems.

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.
