Dark Matter Heats Up Then Moves Away During Star Formation In Dwarf Galaxies

A new study found that dark matter can heat up and then move away from the center of galaxies. This phenomenon called dark matter heating is typical of any star-forming galaxy.

Dark Matter Could Be Primordial Black Holes That Were Formed Right After The Universe Was Born

Is dark matter composed of ancient black holes nearly as old as the universe? Researchers ran computer simulations in the hope of finding evidence of primordial black holes in dwarf galaxies halos, where much of dark matter is located

Star Clusters Can Unveil Nature Of Dark Matter At The Center Of Dwarf Galaxies

Researchers developed a new method to measure the amount of dark matter at the center of tiny dwarf galaxies using star clusters. Their work may eventually unveil the nature of dark matter.

Synchronized Dance Of Dwarf Galaxies Challenges Chaotic Dark Matter Cosmology

Astronomers assumed that only the Milky Way and the Andromeda galaxies are surrounded by dwarf galaxies moving in an orderly manner. Recently, they discovered a more distant neighbor that raised questions against existing cosmological theories.

Astronomers Discover 7 Dwarf Galaxy Groups That May Eventually Merge, Form Larger Galaxies

Seven groups of dwarf galaxies were discovered by astronomers in conditions ideal to a merger forming a bigger galaxy. This has reinforced the theory that mature galaxies were formed by the amalgamation of smaller galaxies several billions of years ago.

Milky Way's Dwarf Galaxy Neighbor IC 1613 Is A 'Clean Freak'

One of Milky Way's neighbors, the IC 1613, was found to have very minimal dust thus gaining the nickname 'clean freak.' The dwarf galaxy is able to provide astronomers with more precise information due to its high level of clarity.

Green Pea Galaxy Gives Scientists Clues About The Early Evolution Of The Universe

Scientist from different research organizations have discovered how compact cosmic structures known as green pea galaxies helped trigger the ionization of hydrogen in the universe. It is believed that this event allowed the universe to enter another stage of its early formation.
