Abstract:
Cosmological simulations predict that galaxies form in groups and filaments where the interplay between the cold gas flowing inside galaxies and outflowing winds play a key role in growth of galaxies with time. While this picture clearly emerges from simulations, observations of this baryon cycle remain scarce. In the first part of the talk I will discuss our efforts to understand the baryon cycle - galactic (in)outflowing gas using metal absorbers in quasar spectra over cosmic timeline as well as to investigate the link between the pristine neutral hydrogen (H I) gas to star-formation within and around galaxies at cosmic noon. In the second part of the talk, I will discuss the elusive X-shaped radio galaxies, showing two sets of radio jets, and discuss the possible origin of X-shaped phenomena.
