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... Dr. George Heald |

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... M.Sc.

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... Dr. Corrado Trigilio |

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...

Finally, we will analyze how different well known planetary systems These concepts will then be applied to several... Dr Cristian Beauge |

Inouye Solar Telescope 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... Dr. Bruce Elmegreen |

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... Dr. Nadine Neumayer |

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... Dr. Debra Elmegreen |

Non-thermal emission processes in the jet cover the whole electromagnetic spectrum from radio wavelengths to TeV gamma rays, with a characteristic double-humped Spectral Energy Distribution (SED). Relativistic amplification effects on the observed fluxes make their jets ideal candidates for detection at any wavelength. A physically... Dr. Giacomo Bonnoli |

On the effects of Initial Mass function on the galactic chemical enrichment: the role of Pair Instability Supernovae We built new sets of chemical yields from massive and very massive stars up to Mi ~ 350 Msun, by combining the wind ejecta extracted from our hydrostatic stellar evolution models with explosion ejecta from the literature. Using a simple chemical evolution code we analyse the effects of adopting different yield tables by comparing predictions against observations of stars in the solar vicinity. Our study indicates that PISN played a significant... Dr. Sabyasachi Goswami |
