The QuaStar Survey (Bish et al. 2021) pairs absorption-line measurements of quasars and galactic stars along similar lines of sight to constrain the contents of our galaxy's circumgalactic medium
Searches for the galaxies associated with low-metallicity circumgalactic clouds reveal one population of clouds associated with galactic halos and another population that appears to be more distant from detectable galaxies
The strong correlation between atmospheric temperature and central black hole mass among massive galaxies is consistent with a linear relationship between black hole mass and the energy required to lift the atmosphere
Our new work shows how better resolving the thermodynamics of galactic outflows boost their energetics, and thus their potential efficiency at regulating galaxy growth over cosmic time.
A serendipitous streak discovered in Hubble Space Telescope images might come from a runaway black hole hurtling through the atmosphere of a distant galaxy.

Hubble observations of high-ionization absorption lines indicate that the Large Magellanic Cloud has extended halo gas at a temperature of several hundred thousand degrees
