Dynamical mechanisms are essential to exchange angular momentum in galaxies, drive the gas to the center, and fuel the central super-massive black holes.

Observations of X-rays coming from outside the solar system were pioneered in 1962 by Riccardo Giacconi and colleagues. From that very day, it became evident that X-rays would reveal a very different Universe to that shown by optical or radio telescopes.

This presentation will focus on recent work aimed at understanding the formation and early evolution of massive protostars. The massive  (M>8 Msol) stars into which these evolve are the primary drivers of galactic ecosystems.

The detection of significant gamma-ray emission from about a-dozen radio-loud narrow line Seyfert 1 (NLSy1) galaxies by Fermi-Large Area Telescope has opened up a realm to explore the physical conditions needed to launch relativistic jets in a different central engine and host galaxy environment

Massive black holes weighing from a few thousands to tens of billions of solar masses inhabit the centers of today's galaxies, including our own Milky Way. Massive black holes also shone as quasars in the past, with the earliest detected a mere one billion years after the Big Bang.

The requirement for more robust statistical tools is becoming increasingly higher owing to the demands of various large programmes and the technological advancement producing high-sensitive observations across the electromagnetic spectrum.

After the scientific success of the two first flights of the Sunrise stratospheric balloon mission, the international consortium led by MPS (Göttingen, Germany) decided to re-issue the mission for a third time.

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.
