e-TidalGCs project. Galactic globular cluster

Additionally, we investigate how the distribution and extension in the sky of the simulated streams vary with the Galactic potential by making use of three different models, either containing a central spheroid, not containing one, or containing a stellar bar. Overall, our models predict that the mass lost by the current globular cluster population in the field from the last 5Gyrs is between 0.3-2.1x10^7^M_{sun}_. This amount is comparable to a value between 7-55% of the current mass.

Most of this lost mass is found in the inner Galaxy, with the half-mass radius of this population being between 4-6kpc. The outputs of the simulations will be publicly available, coinciding with the unique opportunity presented by the delivery of the ESA Gaia mission and complementary spectroscopic surveys. Their exquisite data will offer the possibility to carry out novel comparisons with the models discussed in this work.
