Ultra-diffuse galaxies (UDGs) are one of the most discussed topics in extra-Galactic astronomy in the last lustrum given their puzzling properties: they have luminosities typical of dwarf galaxies, but optical scale lengths similar to very massive spirals.

Most stars have spatial velocities within a few km/s of the average velocity of their surroundings and can be considered to be gravitationally trapped.

One of the ways of following up on the success story of CALIFA is to refine the spatial resolution, and MUSE is the tool for that. Its superb image quality allows for a different kind of science.

Planetary nebulae are some of the most strikingly beautiful astrophysical phenomena known, gracing many a glossy-paged, coffee-table book and earning them the nickname "cosmic butterflies".  Classical stellar evolutionary theory states that all intermediate mass stars should produce a planetary n

With significant new observing capabilities, centimeter-wavelength radio astronomy is currently in a renaissance leading up to the advent of the Square Kilometre Array (SKA), highlighting new opportunities and also technical challenges.

Astrophysical masers are a unique probe of rapid transition phases of stellar evolution such as birth of stars, evolution of hyper and ultra-compact HII regions, long-period stellar pulsation with copious mass loss in their final evolution, and death of stars exhibiting preplanetary and planetary

Astronomical instrumentation has greatly advanced over the last 40 years: with digital detectors, space telescopes and +8m class ground-based telescopes for example.

During the next year, the J-PAS survey will start imaging the northern sky with a unique photometric system composed of 56 narrow and 4 broad bands.

Stellar proper motion studies in the centre of the Milky Way have been typically limited to the Quintuplet, Arches, and central parsec clusters.

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.
