The HI Content of Red Geyser Galaxies

Abstract

Red geysers are a specific type of quiescent galaxy, denoted by twin jets emerging from their galactic centers. These bisymmetric jets possibly inject energy and heat into the surrounding material, effectively suppressing star formation by stabilizing cool gas. In order to confirm the presence and evolutionary consequences of these jets, this paper discusses the scaling, stacking, and conversion of 21-cm HI flux data sourced from the HI-MaNGA survey into HI gas-to-stellar mass (G/S) spectra. Our samples were dominated by non-detections, or galaxies with weak HI signals, and consequently by HI upper limits. The stacking technique discussed successfully resolved emission features in both the red geyser G/S spectrum and the control sample G/S spectrum. From these stacked spectra, we find that on average, red geyser galaxies have G/S of 0.086 $\pm$ 0.011(random)+0.029(systematic), while non-red geyser galaxies of similar stellar mass have a G/S ratio of 0.039 $\pm$ 0.018(random)+0.013(systematic). Therefore, we find no statistically significant evidence that the HI content of red geysers is different from the general quiescent population.
