TalkKinematics and stellar population gradients as fingerprints of past mergers in elliptical galaxies
The formation and evolution of early-type galaxies constitutes a long-standing and crucial problem in cosmology. In all hierarchical clustering models within a...

TalkLarge scale structures and galaxy evolution in the COSMOS Survey
The COSMOS survey is the largest high redshift galaxy evolution survey ever done -- imaging 2 square degrees with all major space-based and ground based...

TalkLocalized starbursts in dwarf galaxies produced by impact of low metallicity cosmic gas clouds
Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver of star formation over cosmic history. Except in very dense...

PublicationLyα Emitting Galaxies (LAEs) at Cosmic Dawn: Implications and Predictions
The detection of Lyα emitting galaxies (LAEs) puts severe constraints on the reionization history. In this paper, we derive the properties of very high-z LAEs...

NewsMagnetic turbulence hidden in the Whirlpool Galaxy
There is a force hidden deep inside galaxies: magnetic fields. Invisible to conventional telescopes, they are a factor in galaxy evolution, regulating the...

TalkMeasuring a Galaxy: Morphology, Mass, Environment and Evolution
What can the shape and size of a galaxy tell us about how it has evolved across cosmic time? Which evolutionary mechanisms are important, or relevant, and which...

PublicationMIGHTEE-HI: Evolution of HI Scaling Relations of Star-forming Galaxies at z < 0.5
We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform spectral stacking of 9023 spectra of star-forming...

TalkNegative feedback in the most powerful active galaxies - NO STREAMING -
Evidence for an intimate connection between supermassive black hole (SMBH) growth and the evolution of galaxies is nowadays compelling. Not only have SMBHs been...
