What are the leading theories behind the formation of dwarf galaxies?

AI Thread Summary
Dwarf galaxies are believed to be the building blocks of larger galaxies like the Milky Way, originating from structures that have not yet merged with others. The leading theories suggest that their formation is tied to a hierarchical model of structure formation, characterized by violent mergers and accretion events. This process began after the recombination era, approximately 400,000 years post-Big Bang. Current dwarf galaxies represent those that have not undergone significant collisions to evolve into larger systems. Understanding these formation theories is crucial for grasping the overall evolution of galaxies.

How do these come about, also what are the leading theories behind the formation of these objects?

I am not sure about this, but I think that dwarf galaxies are considered to be the origin or the seeds of bigger ones like the Milky Way. Currently existing dwarf galaxies are the ones that have not underwent enough collisions with others and have not accreted to form bigger galaxies. The current model of structure formation assumes a very violent history of mergers of structures that were accreting hierarchically. This process starts after recombination (the formation of the cosmic radiation background) at ~ 400,000 years after the big-bang. If I am right then you question is about the origin of galaxies at all.

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...
