What redshift (z) corresponds to galaxy GN-z11 appearing approximately 400 million years after the Big Bang?

z ",

The galaxy GN-z11 holds a specific position in the history of deep-field observations, confirmed to possess a high redshift value. The text explicitly states that GN-z11 was confirmed to have a redshift of approximately $z \approx 11.1$. This specific redshift value is directly associated with a calculated look-back time that translates to observing the galaxy when the universe was very young, estimated to be roughly 400 million years after the Big Bang event. The other options, $z=1, z=3,$ and $z=6$, correspond to much earlier epochs in the universe's history according to the provided table (e.g., $z=1$ is about 7.7 billion years ago, and $z=6$ is about 12.5 billion years ago, or the end of the 'Dark Ages'). Therefore, $z \approx 11.1$ is the correct measure linked to that early observational window for GN-z11.
