A journey into the Perseus cluster of galaxies
The central black hole of active galaxies accretes large amounts of matter and powers jets of relativistic particles that can propagate beyond the host galaxy. Radio galaxies are particularly bright at ∼ GHz frequencies, when the accelerated electrons interact with the magnetic field and produce strong synchrotron emission. Such galaxies residing in clusters evolve in a hot, diffuse, X-ray emitting plasma (the intracluster medium, ICM) which is...

Destroying Planetary Systems
Modern astronomy invests a large amount of effort to search and characterise planetary systems around solar-like stars. In particular, at early stages of their formations in proto-planetary disks. However, we barely know much about the capacities of the planets to survive the harsh environments produced by their host stars during their evolution. In this talk, I will describe the effects a planet can produce by helping shape the mass loss of...

Is it possible to simulate time machines in a laboratory?
General Relativity is the most succesful theory we have for describing gravitational phenomena. Its range of applicability is vast: from solar system scales to cosmological scales. It is well-known that GR allows the existence of time machines: devices that are able to generate Closed-Timelike-Curves (CTCs). Although these kind of objects are allowed in GR, most researchers believe that they cannot occur on macroscopic scales. However, it is...

Imaging the supermassive black hole at the galactic center with the EHT
We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A*), the Galactic center source associated with a supermassive black hole. These observations were conducted in 2017 using a global interferometric array of eight telescopes operating at a wavelength of λ = 1.3 mm. The EHT data resolve a compact emission region with intrahour variability. A variety of imaging and modeling analyses all support an image that...

SO Coloquio: Stellar clustering connecting the formation and evolution of galaxies to the formation and evolution of us
The clustered nature of star formation leaves a long-term imprint on galaxies, stars, and planets. At young ages, stellar clustering subdivides galaxies into individual building blocks undergoing vigorous, feedback-driven life cycles that vary with the galactic environment. These units structure the interstellar medium spatially, dynamically and chemically, and collectively define how galaxies form stars. At old ages, the relics of clustered...

SO Coloquio: The cloud-scale baryon cycle across the nearby galaxy population
The cycling of matter in galaxies between molecular clouds, stars and feedback is a major driver of galaxy evolution. However, it remains a major challenge to derive a theory of how galaxies turn their gas into stars and how stellar feedback affects the subsequent star formation on the cloud scale, as a function of the galactic environment. Star formation in galaxies is expected to be highly dependent on the galactic structure and dynamics,...

SO Webloquio: Charting the first billion years of our Universe with the Square Kilometre Array
The first billion years witnessed the dawn of the first galaxies, eventually culminating in the final phase change of our Universe: the Epoch of Reionization (EoR). Recent observations allowed us limited glimpses into these epochs, improving our understanding of the timing of the EoR. However, we still do not understand the first galaxies and black holes, the vast majority of which are too faint to be seen directly in the foreseeable future....

SO Webloquio: Measuring the Magnetic Fields of Exoplanets with Star-Planet Interactions
Planets interact with their host stars through gravity, radiation and magnetic fields. For giant planets orbiting stars within ~20 stellar radii (=0.1 AU for a Sun-like star), magnetic star-planet interactions (SPI) are observable at a range of wavelengths with a variety of photometric, spectroscopic and spectropolarimetric techniques. At such close distances, planets orbit within the sub-alfvénic radius of the star, where magnetic interactions...

Turning Trash into Treasure: How OH megamasers are contaminating next-generation HI surveys and what they can tell us about galaxy evolution
OH megamasers (OHMs) are rare, luminous masers found in (ultra-)luminous infrared galaxies ([U]LIRGs). The dominant OH masing line at 1667 MHz can spoof the 1420 MHz neutral hydrogen (HI) line in untargeted HI emission line surveys. This ambiguity creates a potential source of “contamination” in HI surveys, particularly for next-generation surveys that will reach groundbreaking sensitivities and redshifts. In this talk, I will present...

How the intracluster light is going to change your life!
There are a huge number of astrophysical phenomena that remain barely studied due to the lack of large, multiwavelength and deep optical surveys. This is the Universe with the lowest density of stars, largely unseen by past large field surveys like the Sloan Digital Sky Survey (SDSS). For instance, only a handful of galaxy clusters have been observed with enough depth to witness the intracluster light (ICL), made up of stars that drift freely...

SO Webloquio: When artificial intelligence meets astronomy: celestial object census
Over the centuries, astronomers have continued to improve the performance of telescopes and the techniques for observing and analysing data. Nowadays, humans are building more and more advanced telescopes with larger and deeper observations, reaching terabytes and even petabytes of data. The Square Kilometre Array (SKA) radio telescope, the most ambitious project in astronomy under construction, is expected to produce more than 700 petabytes of...

SO Coloquio: Constraints on the origin of free-floating planets from the mass function
The stellar mass function is a fundamental parameter to constrain star formation models. Although the stellar content has been extensively studied since Salpeter's first work in 1955, the study of the planetary mass regime is only now becoming feasible. I will present a recent census of the Upper Scorpius and Ophiuchus star- forming region, where we identified between 70 and 170 free- floating planets. This is by far the largest sample of...

SO Coloquio: The Antikythera Mechanism and the Mechanical Universe
The Antikythera Mechanism. An astronomical calculator and display device found in a first century BCE shipwreck, it is mechanically more sophisticated than anything known from the subsequent millennium. I want to argue that we should be showing admiration rather than amazement, and that the Mechanism fits rather well into its historic context. But this fit has major implications for the development of humanity’s view of the Universe.

Disks around evolved binaries: do they form second-generation planets?
Most of the planets are formed around young stars. But can they also form around dying stars? The origin of the diversity and complexity of the detected exoplanetary systems stems from how they form in protoplanetary disks. These disks are intensively studied around young stars thanks to the high-angular resolution provided by recent instruments (VLT, ALMA). However, similar disks are also found around evolved stars, namely post-AGB binaries,...

Cosmological QUOKKAS: Proof of concept and early results on the Hubble Constant tension
Distances are one of the most important yet difficult to get quantities in astronomy. Normally, astronomers use redshifts (which are relatively easy to measure) as distance measure, but this only works if one assumes that there is a relationship between redshift and distance. The relationship between redshift and distance was first observationally verified in the 1920s by Edwin Hubble. He found that the further away a galaxy was, the galaxy...

Unexplored outflows in nearby low luminosity AGNs: the case of NGC 1052
NGC1052 is considered the prototype of AGN-LINERs, an AGN family at low-luminosity for which, so far, the role of outflows in their evolution has been studied the less. Thanks to MUSE and MEGARA IFS-cubes we found that the stars are distributed in a dynamically hot disc whereas the ionised gas is detected mostly in the polar direction up to 3.3 kpc. We found evidences evidence of an ionised gas outflow (jet-powered) propagating in a cocoon of...

SO Webloquio: Exploring the transient radio sky with the SKA and its precursors
Radio astronomical observations probe particle acceleration in some of the most extreme environments in the Universe. For example, we can trace the relativistic jets produced by accreting black holes; observe flashes from hyper-magnetised neutron stars; and study the aftermath of stars that are ripped to shreds as they pass close to super-massive black holes. These events provide critical information about the extremes of the Universe, but they...
