A dwarf irregular galaxy in the Lynx-Cancer void is cannibalizing its neighbors.
Deaths of the Smallest Galaxies: Gas Stripping?
Many of the dwarf galaxies of the Milky Way don’t produce stars. Why?
Cosmic Rays and Dwarf Galaxies
Supernovae in dwarf galaxies can produce large amounts of cosmic rays, which can drastically affect the galaxies.
Dust and the Occult
Pairs of occulting galaxies allow for the dust in galaxies to be mapped very accurately and give insight into the attenuation law in the outskirts of galaxies.
Forging metals with dark matter in dwarf galaxies
Since discovered last year, the origin of a disproportionate amount of extreme heavy elements in a dwarf galaxy has been a mystery. Could it be the work of an invisible hand?
Looking for Dwarf Galaxies with Cepheids: A Cautionary Tale
Today we use a new paper to revisit the possible dwarf galaxy discovered 90 kpc from the Milky Way.
