The cycle of conferences on the origin and evolution of bionic galactic halos will take place tomorrow in the Galapagos Islands. Before the event, this Journal interviewed Ericson Lopez and Duncan A. Forbes, organizers of this scientific symposium that will seek a better understanding of the Universe.
What topics will be addressed in the conferences?
Ericson Lopez: The galaxies are formed by a disc, a species of aura that is called the galactic halo. This conference is dedicated precisely to the study of galactic halos. Scientists are going to discuss the new theories, new discoveries, new information on the studies of galactic halos.
What is a galactic halo?
Duncan A. Forbes: We are trying to understand how galaxies are formed and how they evolve. An essential part of galaxies is the halo around each galaxy as it helps to know how these were formed and how they evolved. The outskirts of a galaxy are made up of normal matter, which is known to man, and dark matter.
What is the difference?
Duncan A. Forbes: The Universe has much more dark matter than normal matter, that is called baryonic matter, while the dark matter is called non-baryonic matter. We will focus on the normal matter, which we can see in great parts of galaxies, to help us understand how they were formed.
We would be talking about a galactic fossil.
Duncan A. Forbes: I think it’s a good analogy. We can see galaxies far away from us; it’s like looking back in time, how galaxies were a long time ago. So it’s like watching a fossil that has been dug from the earth, you can see in an exact way how it was a long time ago and that gives us paramount clues about how that galaxy evolved over time into the way we see it now.
When and where will the conferences be held?
Ericson Lopez: This international scientific event will take place from the 13th to the 17th of March. We will be meeting on the island of Santa Cruz and Puerto Ayora. Duncan A. Forbes: We have been working for a year to bring together 120 astronomers from different countries. I come from Australia, and many colleagues come from Europe, America, they will al come to the Galapagos to attend this conference.
