What is the origin of a star cluster, quasars, and pulsars?

Question

Star Cluster: Collection of stars born together. Quasar: Basically a Black Hole. Pulsar: A rapidly rotating Neutron Star.

Quasars (I'll refer to them as Bo's {Black Holes}) and Neutron stars are formed from a star's collapse. Black holes form from larger stars than neutron stars though ( > 8 Solar Masses). Pulsars are then rapidly rotating NS's which are very magnetized (this is a characteristic of all neutron stars though) that emit beams of electromagnetic radiation from their poles. The beam is only detectable when it points to the earth, and a common analogy to this is the lighthouse. Pulsars have rotational periods that vary greatly, but all with the accuracy of an atomic clock.

A Star cluster is a group of stars that were formed at the same time and likely from the same molecular cloud. They stay loosely attracted by their gravity, and eventually stray away from each other.

undefined Star clusters are clouds of gas and dust in space that collapse under their own gravity to form dense regions where stars are born; pulsars are thought to be the remnants of massive stars that have undergone supernova explosions, leaving behind a dense core known as a neutron star, which emits beams of radiation that are observed as pulses as the star rotates; and quasars are thought to be the product of supermassive black holes at the centers of galaxies, which accrete large amounts of gas and dust while emitting enormous amounts of energy in the process.
