    Quasars
AI Thread Summary
Quasars are highly luminous objects powered by particle jets emitted from their poles, with their brightness linked to these jets. The discussion explores the idea that gravitational time dilation near black holes may significantly contribute to the observed redshift of quasars. Participants inquire about the possibility of measuring the redshift of associated galaxies and seek theories that explain jet formation. The conversation highlights the complexities of redshift measurements and the need for further research in this area. Overall, the relationship between quasars, their jets, and redshift remains an intriguing topic in astrophysics.

A Quasar's luminosity is believed to be due to particle jets streaming from it, presumably on the direction of its poles. Reading some of Fred Hoyle's theories (and Halton Arp's) on redshifts, I wondered whether the jets could be forming so close to the "surface" of a black hole that gravitational time dilation would account for a large fraction of the observed redshift.
Has it been possible to measure the redshift of the surrounding galaxy where one is visible? And is there a viable theory about the formation of these jets that could answer this question?

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
