45. Stefano Carniani - CGM enrichment by quasar-driven outflows

14/06/2023, 11:25

Large scale outflows are believed to be an important mechanism in the evolution of galaxies, as they can both suppress and enhance star formation as well as eject gas from their host galaxies and mix the pristine gas from the intergalactic medium and processed material from the galaxy in the circum-galactic medium (CGM). We can study the impact of these large-scale outflows either by tracing...

46. Federico Lelli - Cold gas dynamics in high-z galaxies

14/06/2023, 11:45

High-resolution ALMA observations have opened a new window to study galaxy dynamics at z>1 using cold gas tracers, such as CO, [CI], and [CII] emission lines. In this talk, I will present in-depth studies of individual galaxies at z=1-5 with ALMA data at angular resolutions between 0.05"-0.5". In such galaxies, the cold gas forms dynamically-cold rotation-supported disks with high...

50. Toby Devereaux - Star-forming clumps and their molecular gas content

14/06/2023, 14:20

The peak of galactic star formation occurs between a redshift of 1-3. Galaxies at these redshifts are shown to be dominated by irregular clumpy morphologies. These clumps are suggested to be starbursting and are thought to play a significant role in the growth of the bulge and subsequent evolution of the galaxy itself. Despite being observed in bright UV wavelengths and optical...

51. Francesca Perrotta - H2O emission lines in a strongly lensed dusty star-forming galaxy at z ∼ 3.1

14/06/2023, 14:40

We report ALMA high-resolution observations of water emission lines $p-{\rm{H_2O}} (2_{02}-1_{11}$), $o-{\rm{H_2O}} (3_{21}-3_{12})$, $p-{\rm{H_2O}} (4_{22}-4_{13})$, in the strongly lensed galaxy HATLASJ113526.2-01460 at redshift z $\sim$ 3.1. From the lensing-reconstructed maps of water emission and line profiles, we infer the general physical properties of the ISM in the molecular clouds...

52. Gayathri Gururajan - Probing the gas reservoirs of high-redshift lensed dusty

14/06/2023, 15:00

The discovery of dust-enshrouded star-forming galaxies in the early Universe has opened new questions in understanding the formation and evolution of galaxies through cosmic times. With the breakthrough in sub millimeter astronomy spearheaded by facilities like Atacama large millimeter/sub-millimeter array, a large diversity in the population of dusty star-forming galaxies (DSFG) has been...

53. Marika Giulietti - Synergistic Study of High-z Strongly Lensed Dusty Star-Forming Galaxies with ALMA: Insights into Galaxy/AGN Co-evolution

14/06/2023, 15:20

Co-evolutionary models between supermassive black holes and their host galaxies predict that processes in the early stages of galaxy formation, such as nuclear activity and star formation, are strictly related and coordinated in time. Dusty star-forming galaxies (DSFGs) are ideal laboratories to test this scenario, as they constitute the bulk population at the peak of cosmic star formation,...
