Galaxy clusters host radio emission in different flavours and on very different angular scales: from the compact emission of staburst galaxies and "radio quiet" AGN, to the extended lobes of the more powerful radio galaxies, to the impressive megaparsec scale diffuse emission associated with the ICM in the form of halos and relics. The latter, as well as the lobes of radio galaxies, are best...
Fast radio bursts are enigmatic millisecond-scale radio transients reaching us from distant galaxies. Their studies are expected to yield information on their necessarily extreme progenitors - young magnetars, merging neutron stars, and/or even more exotic phenomena - as well as the cosmological distribution of gas in our Universe. The SKA promises to yield both the largest and deepest sample...
The interstellar medium is the lifeblood of galaxies, providing the raw material from which stars are born, and to which they return much of their matter when they die. Some of the biggest unknowns in galaxy evolution are tied to the detailed physics of the ISM: e.g. the multiple phase transitions needed to convert warm HI into star-forming gas, the role of feedback in regulating star...
To understand the origin of life in the Universe is one of the most outstanding questions in Astrophysics. Complex organic molecules (COMs; molecules containing carbon with more than 6 atoms) are believed to be the building blocks of prebiotic molecules and have been observed at several stages of the star and planet formation process: in cold and dense prestellar cores, in the hot-corinos...
