SO Web-Colloquia: Thematic area 9 of the CSIC’s new White Book: Understanding the basic components of the Universe, its structure and evolution
CSIC is about to publish a White Book to define its scientific strategy for the coming decades. The White Book contains chapters on 14 different thematic areas. One of the main goals of this exercise is to increase collaboration between research groups and institutes of the CSIC. Particular value is set on inter- and cross-disciplinary work. Each thematic area defines a set of “challenges”, key scientific questions for the coming decade(s) in...

SO Web-Colloquia: Thematic area 12 of the CSIC’s new White Book:Our Future? Space colonization and exploration
The exploration and colonization of the outer space represents a foreseeable future for the Humanity. This endeavour involves deepening our knowledge about the formation and evolution of the solar system, of other planetary systems, emergence of life (and its prospects once it exists), the interaction between Earth and Space (particularly with its Sun) and the impact of space conditions (radiation, gravity, etc.) on Earth-borne organisms....

SO Web-Colloquia: Searching for the formation mechanisms of brown dwarfs
New generation of Submillimeter facilities in the North of Chile, like the APEX antenna and the Atacama Large Millimeter/submillimeter Array (ALMA), offers for the first time the possibility for studying the formation of stars, brown dwarfs, and planets with unprecedented sensitivity and angular resolution in the millimeter/submillimeter regime. The formation of Brown Dwarfs (BDs) is a debated topic of research. The most widely discussed...

SO Web-Colloquia: Primordial black holes, gravitational waves and dark matter
More than twenty years ago, we predicted that massive primordial black holes (PBH) would form via the gravitational collapse of radiation and matter associated with high peaks in the spectrum of curvature fluctuations, and that they could constitute all of the dark matter (DM) today. In 2015, we predicted the clustering and broad mass distribution of PBH, which peaks at several Msun, and whose high-mass tails could be responsible for the seeds...

From direct imaging to gravitational waves: tracing the life of gas giant exoplanets
In two decades, the field of exoplanet science has undergone nothing short of a revolution. With such a variety of planetary systems detected, the next step in exoplanet research is to characterise the properties of these systems. In this talk I will focus on “life and adventures” of gas giant exoplanets, and present how future space missions such as JWST, ARIEL and LISA will help us understand the nature, formation and evolutionary history of...

The Sun shows activity across a wide range of size and energy scales. We shall take a journey from the smallest scale events to the largest energy releases in the solar system. The energy release is due to the magnetic fields on the Sun and how they interact. Using EUV/UV spectroscopy different layers of the solar atmosphere can be probed in order to understand the physical processes that occur. The EUV imaging spectrometer onboard the Hinode...

Our Galactic Center: A Unique Laboratory for the Physics & Astrophysics of Black Holes
The proximity of our Galaxy's center presents a unique opportunity to study a galactic nucleus with orders of magnitude higher spatial resolution than can be brought to bear on any other galaxy. After more than a decade of diffraction-limited imaging on large ground-based telescopes, the case for a supermassive black hole at the Galactic center has gone from a possibility to a certainty, thanks to measurements of individual stellar orbits.

So Web-Colloquia: The star formation process on cloud-scales in nearby galaxies
Where do stars form and how is their formation regulated across galactic disks are two critical questions for our understanding of the star formation process. High angular observations of nearby galaxies allow us to sample the star formation process across entire galactic disks reaching now regularly the scales of the star-forming units, namely Giant Molecular Clouds (GMCs) and HII regions. Such data provide new insights on the molecular gas...

SO Web-Colloquia: Recent findings on nova explosions
Nova events are the result of the interaction of low-mass binary systems. A compact white dwarf (WD) accretes material from an old and cold companion until a thermonuclear runaway takes place on its surface. Such explosive events can be considered the scaled-down siblings of supernova (SN) explosions, but its study has many advantages over SNe, as nova events are more numerous (some systems even exhibit recurrent explosions within decades) and...

The growth and evolution of the most massive black holes, and their host galaxies, can be followed from z=7 and even earlier. The critical events that shape this evolution are major mergers, Eddington or super-Eddington accretion, violent star formation, and powerful outflows. I will present the results of a systematic study of 40 AGN at z~4.8 using Gemini, VLT, Herschel and ALMA. Our recent (2019) ALMA data allow a fresh look at major mergers...

The power of low activity black holes
It is possible that most galaxies host a black hole at the centre, most of the time this being in a relatively quiescent state. The so-called low luminosity Active Galactic Nuclei are characteristic of this phase. These objects represent the vast majority of the active galactic nuclei (AGN) population in the near universe, and still the least conforming class with the standard AGN scenario. Their low luminosity is at odds with their often...

Dynamical mechanisms are essential to exchange angular momentum in galaxies, drive the gas to the center, and fuel the central super-massive black holes. While at 100pc scale, the gas is sometimes stalled in nuclear rings, recent observations reaching 10pc scale, or 60mas with ALMA, have revealed, within the sphere of influence of the black hole, smoking gun evidence of fueling. Observations of AGN feedback will be described, together with the...

X-ray Astronomy for non (X-ray) astronomers
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. Indeed, X-rays are typically produced in the environment of black holes, or where the ambient temperature exceeds millions of degrees. X-ray telescopes (which, for good reason, are in orbit)...

Peering into the Dark: Probing the Formation and Early Evolution of Massive Stars
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 energy and nuclear processed material these massive stars inject into their enviroment during their lives and ultimately as supernovae, shapes the physical and chemical evolution of the ISM in galaxies. These stars...

Exploring the origin of gas-rich ultra-diffuse galaxies with HI kinematics
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. This intriguing combination is hard to explain, and up to date the precise formation mechanism of UDGs remains unknown. With the goal of learning more about their origins, our group has...

HI mapping of nearby dwarf galaxies with SKA pathfinders: unique capabilities of KAT-7 and MeerKAT
Dwarf galaxies are by far the most numerous galaxies in the Local Universe.

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.

From protostars to planets: the astrochemical link
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. Although this process takes a few million years, now we think that the final chemical composition of the gas and dust in the proto-planetary disk is to a large extent determined by the chemical evolution in the natal cloud. Determining the...

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".
