HST observations infer ~500 solar masses of inflowing low-metallicity gas in M81's central parsec that can sustain its advection-dominated accretion flow for 10^5 years.

The Missing Hard Photons of Little Red Dots: Their Incident Ionizing Spectra Resemble Massive Stars

Inflowing Gas in the Central Parsec of M81
HST observations infer ~500 solar masses of inflowing low-metallicity gas in M81's central parsec that can sustain its advection-dominated accretion flow for 10^5 years.
