Most distant cosmic jet providing clues about early universe

E-Mail
Astronomers using the National Science Foundation s Karl G. Jansky Very Large Array (VLA) and Very Long Baseline Array (VLBA) have found and studied the most distant cosmic jet discovered so far a jet of material propelled to nearly the speed of light by the supermassive black hole in a quasar some 13 billion light-years from Earth. The quasar is seen as it was when the universe was only 780 million years old, and is providing scientists with valuable information about how galaxies evolved and supermassive black holes grew when the universe was that young.
The studies indicate that the quasar a galaxy harboring a black hole 300 million times more massive than the Sun has a jet of fast-moving particles only about 1,000 years old. While other quasars have been found at its distance and beyond, it is the first found at such a distance with the strong radio emission indicating an active jet. Only a small fraction of quasars have such jets. ....

ESOblog - In conversation with Catherine Cesarsky:

ESOblog
8 March 2021
How Catherine’s different leadership roles have shaped her perspective of science.
What were Catherine’s most memorable moments as Director General of ESO.
What Catherine is most looking forward to in the future of astronomy.
In celebration of International Women’s Day, we spoke to Catherine Cesarsky, who was ESO Director General between 1999 and 2007. Since then, she has taken on a number of prestigious leadership roles including President of the International Astronomical Union and High Commissioner for Atomic Energy in France. We find out how she got into astrophysics, about her most recent leadership role and what she is looking forward to in the future. ....

Tiny photonic devices could be used to find new exoplanets, monitor our health, and make the internet more energy efficient. Researchers from Chalmers University of Technology, Sweden, now present a game changing microcomb that could bring advanced applications closer to reality.
A microcomb is a photonic device capable of generating a myriad of optical frequencies - colours - on a tiny cavity known as microresonator. These colours are uniformly distributed so the microcomb behaves like a ruler made of light . The device can be used to measure or generate frequencies with extreme precision. ....
