Studying the absorption signatures of H I Lyman-α in the warm-hot circumgalactic medium with TNG50

P. Aparicio Marcos, P. Richter, M. Sparre +2

In this study, we investigate the spectral signatures of neutral hydrogen Lyman-$\hat{I}\pm$ absorption arising from the warm-hot gas component of the circumgalactic medium (CGM) around $z…
