Baryonic solutions and challenges for cosmological models of dwarf galaxies

Nature Astronomy, 2022
Galaxies and their dark-matter haloes have posed several challenges to the dark energy plus cold dark matter (ΛCDM) cosmological model. These discrepancies between observations and theory intensify for the lowest-mass (‘dwarf’) galaxies. ΛCDM predictions

Hunting for massive black holes in dwarf galaxies

Nature Astronomy, 2022
Despite traditional thinking, an appreciable population of massive black holes (that is, more massive than stellar-mass black holes) may be lurking in dwarf galaxies.

Further evidence for a population of dark-matter-deficient dwarf galaxies

Nature Astronomy, 2019
In the standard cosmological model, dark matter drives the structure formation of galaxies and constructs potential wells within which galaxies may form.

Dwarf Irregular Galaxies

2004
Dwarf irregular galaxies at optical wavelengths are small, faint and appear to be unstructured and irregular in shape. They are typically gas-rich, metal-poor systems, with varying levels of STAR FORMATION occurring in a haphazard manner across the ...

Suppression of star formation in dwarf galaxies by photoelectric grain heating feedback

Nature, 2016
Photoelectric heating—heating of dust grains by far-ultraviolet photons—has long been recognized as the primary source of heating for the neutral interstellar medium.
