Andalusia and its role in the discovery of new worlds
In twenty-five years we have gone from thinking that our Solar System was the only one in the Galaxy to knowing that there are thousands of planets already detected and that there could be billions out there.

Nobel Prize in Physics 2020: the black hole in the Milky Way galaxy
Andrea Ghez and Reinhard Genzel were awarded the Nobel Prize in Physics 2020 for their discovery of the massive black hole at the center of the Milky Way. In my talk I will review the history of their research work from a front-line point of view (having worked closely with the two researchers on this topic). I will explain the methods and measurements they used and the strength of their results.

Polarized light in the vicinity of supermassive black holes
Relativistic jets produced by supermassive black holes are the most energetic astrophysical objects known and can be observed up to enormous distances and very early ages in the universe. This lecture will focus on these objects, and more specifically on their main characteristics and the extra information provided by studying the polarized light they emit, as well as the main questions that remain to be answered to fully understand them.

The Symbolic Primate. How language and culture made us human
Humans diverged from our closest relative, the chimpanzee, about seven million years ago, a relatively short time from an evolutionary point of view. Biological continuity with the chimpanzee is evident in many physiological and behavioral aspects; equally evident is the cognitive gap between the two species. In this talk I will attempt to outline the process of hominization based on data from paleontology, genetics, bioinformatics,...

The enigmatic assembly process of the Sombrero galaxy
The Sombrero galaxy, a strange hybrid between a spiral and an elliptical galaxy, has been observed in detail to look for clues about its formation process. A large elliptical structure surrounding the galaxy, the product of a minor merger with another galaxy, has been characterised, but the origin of its shape remains unknown

Precision cosmology: now what?
The standard cosmological model (the LCDM model) has been established and its parameters are now measured with unprecedented precision. This model successfully describes observations from widely different epochs of the Universe, from primordial nucleosynthesis all the way to the present day. However, there is a big difference between modelling and understanding. The next decade will see the era of large surveys; a large coordinated effort of...

Revealing cosmic magnetism with the Square Kilometre Array and its pathfinders
Magnetism is an enigmatic but crucial element of our Universe. The structure and strength of magnetic fields are important for a full understanding of astrophysics over a tremendous range of scales: from stellar systems, to star forming regions, the properties and evolution of individual galaxies, galaxy groups and clusters, and even as a major element of the Cosmic Web. The Square Kilometre Array (SKA) promises to deliver a revolutionary view...

SO Colloquium: Interstellar planetesimals: 1I/Oumuamua and 2I/Borisov
Extensive surveys of extrasolar planets and of circumstellar disks around nearby stars show that planets and dust-producing planetesimals, similar to the asteroids, Kuiper belt objects and comets in our solar system, are ubiquitous around others stars. The planetesimal population of the young solar system was very numerous initially but the majority of the objects ended up ejected due to gravitational perturbations with the planets and other...

K-band interferometric imaging of the M-type Mira star ‘R Car’
The final stage of low to intermediate-mass stars, also known as the asymptotic giant branch (AGB), presents circumstellar envelopes (CSE); however the mechanisms that lead to the formation of these structures, at least in M-type AGBs, are still not well understood. In order to grasp the characteristics of the CSE, it has been found that the CO molecule plays an important role due to its stability against dissociation, making it a tracer of the...

Is the Bremer Deep Field Ionised at z=7?
The talk will show that the population of star forming galaxies in the Bremer Deep Field (BDF) has formed two large ionised bubbles. The sources in the BDF have been completed with a set of expected, though not detected, low luminosity sources at z ~ 7. We have estimated the number of ionising photons produced per second by the different star forming galaxies in the BDF and have compared it with the number that would be required to reionise...

SO Webloquio: Auroral Radio Emission in stars and exoplanetary systems
In recent years, an interesting type of coherent radio emission has been detected in a wide variety of stars across the HR diagram, from hot magnetic A-B MS stars to Ultra Cool dwarfs: the Auroral Radio Emission (ARE), previously observed by spacecrafts in the magnetosphere of planets of the Solar System. Very different objects are showing the same phenomenon. What do they have in common? The first star with ARE was CU Virginis, an early type...

SO Webloquio: Star-formation and accretion in galaxies from near to far: the LeMMINGs and eMERGE e-MERLIN legacy programmes
Radio emission provides a uniquely powerful and unobscured probe of the two key physical processes underway in, and powering, galaxies and their evolution: Accretion on to their central SMBH, and star-formation processes. To explore these processes, and their role in galaxy evolution, we require very high resolution (sub-arcsecond or better), sensitive imaging at radio wavelengths across large samples of galaxies in both the local and distant...

The Sun represents a template for much of our understanding of the workings of a "cool" star, and its proximity allows us to observe exquisite details at its surface, with current facilities routinely reaching resolutions of few hundreds of km on the solar disk. Yet, many questions still linger, in particular concerning the actual mechanism(s) that create and maintain a hot outer atmosphere (chromosphere, transition region and corona) as well as...

SO WebLoquio: Regularly-spaced 8 micron cores as tracers of the earliest stages of star formation in the spiral arms of nearby galaxies
Archival Spitzer Space Telescope images of most nearby spiral galaxies show prominent 8 micron emission cores when viewed with an unsharp mask technique. These cores have the IR colors of young star-forming regions, typically a million years old, behind several tens of magnitudes of optical extinction. They are usually invisible in optical images, and yet the sum of their masses divided by their likely age is comparable to the total star...

SO Webloquio: Nuclear star clusters
I review the current knowledge about nuclear star clusters (NSCs), and the spectacularly dense and massive assemblies of stars found at the centers of most galaxies. Understanding the formation, growth, and ultimate fate of NSCs is crucial for a complete picture of galaxy evolution. There is a clear transition mass in galaxies of ∼ 10^9 Msol where the characteristics of NSCs change. I argue that at lower masses, NSCs are formed primarily from...

SO Webloquio: Star-forming Complexes in Local Mergers and High Redshift Galaxies
Disk galaxies at high redshift contain star-forming complexes, or clumps, whose masses and sizes far exceed those of clumps in local non-interacting galaxies. However, our recent Hubble Space Telescope observations reveal that local merging galaxies can form massive clumps like those at high z, with the same range of physical size, surface density, age, and star formation rate. These similarities, combined with the loss at high redshift of low...
