ESA's Gaia EDR3 & DR3 data

Royal Observatory of Belgium (ROB), Brussels, 2019 - DPAC + CU6

During the whole year of 2019, I was based at ROB, working on the valuable Gaia data preparation, closely collaborating with Dr. Ronny Blomme, Dr. Yves Frémat and Dr. Alex Lobel. Having the stellar spectra, I was evaluating the final values of Radial and Rotation velocities of stars of our Milky Way Galaxy with respect to space telescope parameters.

Developing a new model of Star-formation efficiency in the early Universe.

Hmm, one can predict the dynamics of galaxies only by the distribution of baryons...

Is there a fundamental acceleration scale in the gravitational systems? Then, there should be a transition regime...

Is the Universe indeed expanding, or it this just one interpretation of the data? If so, why its rate of stretching is unclear?

Can a gigantic Void be responsible for the apparent accelerating behavior?

Are there alternatives of the current standard paradigm of the Big-Bang Cosmology? Can the light be tired?
