First [may be partial] is: A Cephid Variable Star. Quasars and other Gamma Ray sources [colliding Neutron Stars, and 'coalescing' Pairs of Black Holes for example] are also closely related.

All things, except black holes, are luminous. That includes stars. You might think that some other things are not luminous but that's because you can't see the kinds of light that they emit.
Two or more different kinds of atoms chemically combine to form a compound. The atoms make a molecule of that compound, which is the smallest individual component (part or piece) of that substance.P.S. That makes the answer Molecule.
Pulsars are located every where around the universe keep in mind pulsars are neutron stars so that means they were formed by large stars that have aged and died out
No, not all neutron stars are pulsars. Pulsars are a type of neutron star that emits beams of radiation, which can be detected as pulses of light. Some neutron stars do not emit these beams and are not classified as pulsars.
The collapse of massive stars - the same as neutron stars.
No, not all neutron stars are pulsars. Pulsars are neutron stars that emit beams of radiation that are detectable from Earth as rapid pulses of light. While many neutron stars are pulsars, not all neutron stars exhibit this pulsing behavior.
pulsars
Because I am interested in neutron stars.
Pulsars are produced from the remnants of massive stars that have undergone supernova explosions. When these stars collapse, they form neutron stars, which are incredibly dense and possess strong magnetic fields. As the star rotates, the misalignment of its magnetic axis with its rotation axis emits beams of radiation, which can be detected as regular pulses of light or radio waves when they sweep past Earth. This phenomenon results in the characteristic pulsing behavior of pulsars.
Pulsars are not only a kind of neutron star, they are neutron stars. See related question.
Not all neutron stars are seen as pulsars because pulsars emit beams of radiation that are only visible if they are pointed towards Earth. If a neutron star's beams are not aligned with our line of sight, it will not appear as a pulsar.
The short length of pulsar pulses eliminate normal stars as possible pulsars because normal stars do not have strong enough magnetic fields.
Pulsars --------------------------------------------Correction Pulsars are neutron stars that emit pulsating EM radiation at predictable frequencies. Obviously neutrons stars (something massive stars can collapse into when they die) are not the elementary particles of the universe. Therefore, 'quarks'.
Yes, pulsars are often found in supernova remnants. Pulsars are rapidly rotating neutron stars that emit beams of radiation, and they are formed when a massive star undergoes a supernova explosion. The remnants of the supernova provide the environment from which the pulsar originates.
