A perturbed Milky Way with Gaia DR2 and EDR3
Teresa Antoja
Universitat de Barcelona
Thanks to the large amount of data delivered by the Gaia satellite and their excellent precision, in the last three 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 Gaia phase spiral and ridges in the in-plane velocities. 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.
Teresa Antoja obtained her PhD at the University of Barcelona in 2010. She then moved to the Kapteyn Astronomical Institute in Groningen to work with Amina Helmi for three years. After this, she got the ESA Research Fellowship, and the Marie Curie Fellowship to work at the Institut de Ciències del Cosmos of the University of Barcelona. She is now a Ramon y Cajal Fellow at the same institute. Her research is mostly related to the dynamics of the Milky Way and she is also involved in the Gaia consortium.
