Relativistic Effects of our Galaxy's Motion on Circles-in-the-sky
M. O. Calvao, G. I. Gomero, B. Mota +1
We study the geometric effects of our galaxy's peculiar motion on the circles-in-the-sky. We show that the shape of these circles-in-the-sky remains circular, as detected by a loca…
A Note on the Robustness of Pair Separations Methods in Cosmic Topology
A. Bernui, G. I. Gomero, B. Mota +1
The pair separations statistical methods devised to detect the topology of the universe rely on the accurate knowledge of the three-dimensional positions of the cosmic sources. The…
"Circles in the Sky" in twisted cylinders
G. I. Gomero
It is shown here how prior estimates on the local shape of the universe can be used to reduce, to a small region, the full parameter space for the search of circles in the sky. Thi…
What do very nearly flat detectable cosmic topologies look like?
B. Mota, G. I. Gomero, M. J. Reboucas +1
Recent studies of the detectability of cosmic topology of nearly flat universes have often concentrated on the range of values of given by current observations. Here we stu…
Determining the shape of the Universe using discrete sources
G. I. Gomero
Suppose we have identified three clusters of galaxies as being topological copies of the same object. How does this information constrain the possible models for the shape of our U…
Can We See the Shape of the Universe?
G. I. Gomero
This is a written version of a talk given at the Fifth Friedmann Seminar on recent work in Observational Cosmic Topology done in partial collaboration with Armando Bernui. We addre…
