A new fossil galaxy, discovered by a systematic search of legacy survey photographs using the Mayall 4-meter telescope, led by Drs. David Martinez Delgado, you can teach scientists how galaxies build and validate their understanding of cosmology and dark matter.
Drs. Michelle Collins, an astronomer at the University of Surrey, the U.K., and lead author of the paper announcing the findings, states that they “discovered a new, fragile galaxy star that formed early in the history of the Universe. of astronomy which was not explicitly designed for this purpose. “
Called “Pegasus V,” the tiny GalaxyGalaxy is located on the edge of Andromeda and appears to be just a few stars hidden in the sky.
The discovery was made in collaboration with NSF NOIRLab and the International Gemini Observatory.
Emily Charles, Ph.D. A student at the University of Surrey who was also involved in the study states, “the problem with these galaxies is that they have very few stars that we often use to see and measure their distances. and we have found that its stars are ancient. “
More and more astronomical observations are being explored for obscure galaxies shortly.
The discovery was reported in the Monthly Notices of the Royal Astronomical Society.
