Title: Recent disturbances in the Milky Way with Gaia DR2 and EDR3

Speaker: Teresa Antoja

Abstract: Thanks to the large amount of data delivered by the Gaia satellite and their excellent precision, in the last two years we have experienced a vertiginous progress in the studies of our Galaxy. I will talk about the discovery of unexpected structures in the Milky Way phase-space such as the phase spiral, ridges in the in-plane velocities (now seen at much larger distances from the Sun with EDR3), and waves in the angular momentum and vertical space. Finally, I will discuss how we are trying to figure out whether all these disturbances are consistent with the effects of internal mechanisms such as the bar or the spiral arms, or are produced by the interaction with satellite galaxies.  

Short CV: Dr. Teresa Antoja is a researcher at the University of Barcelona. She got her PhD in 2010 in the University of Barcelona. From 2018 to present, she is the Marie Sklodowska-Curie Individual fellow. She is deeply involved in the Gaia data and science projects. Her main research interests are Galactic Dynamics and Galaxy Formation. She is currently working on the scientific exploitation of the wonderful Gaia. She is also a member of CU9 working on the validation of Gaia data.
