A Quasar is an Active Galactic Nuclei. It is the centre of a galaxy that is shooting out a stream of particles from the centre. The difference between a Quasar and a Blazar is how it is angled towards us. The Milky Way was believed to have been a Quasar once but is currently quiet.
16 de may. de 2024 · However, gravitational waves alter the distance between Earth and these pulsars by warping spacetime, which disrupts the pulsars’ regular beat. Scientists were able to determine that gravitational waves were passing through pulsars by examining minute variations in the ticking rate of various pulsars, with some pulses occurring slightly early and others later.

4 de may. de 2024 · A **pulsar** is a rotating neutron star that sends out periodic pulses of electromagnetic radiation, hence its name. The naming of pulsars consists of the abbreviation “PSR” followed by its ...
30 de abr. de 2024 · The stability of the spin of pulsars and the precision with which these spins can be determined, allows many unique tests of interest to physics and astrophysics. Perhaps the most challenging and revolutionary of these, is the detection of nanohertz gravitational waves. An increasing number of efforts to detect and study long-period gravitational waves by timing an array of pulsars have been ...
