JWST-7329: a rare massive galaxy that formed very early in the Universe. This James Webb Space Telescope NIRCAM image shows a red disk galaxy but with images alone, it is hard to distinguish from other objects. Spectral analysis of its light with JWST revealed its anomalous nature – it formed around 13 billion years ago even though it contains ~4x more mass in stars than our Milky Way does today.
The formation of galaxies is a fundamental paradigm underpinning modern astrophysics and predicts a strong decline in the number of massive galaxies in early cosmic times. Extremely massive quiescent galaxies have now been observed as early as one to two billion years after theDistinguished Professor Glazebrook worked with leading researchers all over the world, including Dr. Themiya Nanayakkara, Dr. Lalitwadee Kawinwanichakij, Dr. Colin Jacobs, Dr.
“This pushes the boundaries of our current understanding of how galaxies form and evolve. The key question now is how they form so fast very early in the Universe and what mysterious mechanisms lead to stopping them from forming stars abruptly when the rest of the Universe doing so.”) was crucial in developing the theoretical modeling of the evolution of dark matter concentrations for the study.
