Gravitational lensing used to observe a distant galaxy

[pinball1970]

TL;DR Summary

This alert came in this morning with some very cool images of the effects of gravitational lensing on a galaxy when it was 3 billion years old.

The effects of jets from a black hole within the galaxy including 'quenching' are discussed.

Predicted by Einstein and now the technique is being used to observe galaxies 11 billion light years away.

Hello,

Thank you for sharing this interesting article and paper. It is fascinating to see evidence of supermassive black hole jets interacting with gas in the early universe. This type of observation can provide valuable insights into the formation and evolution of galaxies.

The concept of "quenching" discussed in the paper is also very intriguing. It is interesting to think about how these powerful jets can potentially impact the growth and activity of galaxies. Further research in this area could help us better understand the role of supermassive black holes in shaping the universe.

I also find it exciting that Einstein's theory of general relativity, which predicted the existence of black holes, is now being used to observe galaxies that are 11 billion light years away. This is a testament to the power and accuracy of his theories.

Thank you for bringing this to my attention. I look forward to reading more about this topic and the potential implications it may have for our understanding of the universe.
