What are Some Important Effects or Phenomena in Astrophysics?

AI Thread Summary
Key phenomena in astrophysics include the Rossiter effect, which relates to the orbital dynamics of exoplanets, and the Yarkovsky effect, which describes how an asteroid's orbit is altered by thermal radiation. Recent discoveries also highlight gravitational waves, which provide insights into cosmic events, and dark energy, influencing the universe's expansion. Other significant effects include the Doppler effect in light from moving objects and the lensing effect caused by massive objects bending light. Understanding these phenomena is crucial for advancing knowledge in astronomy and astrophysics. This information is essential for preparing for competitions like the IOAA.

hi friends
can you help me in collecting systematically some important phenomenon or 'effects' in astronomy and astrophysics like rossiter effect, yarkovsky effect.:cool:

even recently discovered phenomenon and related explanations are welcome.:approve:
 
Astronomy news on Phys.org
actually i am preparing for IOAA 2007 (international olympiad on astronomy and astrophysics.

so i am looking forward to your help
 
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?'
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...

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.
