Determine the distance to TTT J1237327+143535

Determine the distance to the almost-dark galaxy TTT J1237327+143535 in order to establish its precise physical size, stellar mass, and cluster membership.

Background

The paper reports the discovery of TTT J1237327+143535, an extremely low-surface-brightness, low-mass galaxy projected near M87 in the Virgo Cluster. Its physical properties are estimated under the assumption that it lies at the Virgo Cluster distance of approximately 16.17 Mpc.

The authors explicitly state that the galaxy’s distance has not been measured. They support Virgo membership from its projected location and the fact that its stellar populations are unresolved, while acknowledging that a different distance would substantially change the inferred effective radius and stellar mass.
