The SAGA Survey

The SAGA Survey is a spectroscopic survey designed to better understand our Milky Way Galaxy by placing its satellite galaxy population into a broader cosmological context. The SAGA Survey goal is to measure the distribution of satellite galaxies around 100 Milky Way analogs well below the luminosity where predictions and observations diverge.

More survey details and access to data are available on the SAGA Survey website.

Isolated and Field Low Mass Galaxies

The properties of isolated low-mass galaxies provide insights into the internal processes regulating star formation.

Isolated and Field Low Mass Galaxies

Milky Way Dwarf Galaxies

The Local Group’s population of satellite galaxies and star clusters include the lowest mass and least chemically enriched stellar systems in the known Universe. Proximity enables spectroscopic observations of individual stars, providing exquisite measurements of their kinematics and chemistries.
