Present-day column densities for ions of different species: H I (upper left), C IV (upper right), O VI (bottom left) and Si II (bottom right). On the x-axis, the impact parameter b is normalised by the virial radius of Bashful. The solid lines represent the present-day column densities computed for our simulation (red) with the superbubble feedback model, and for the simulation presented in Shen et al. (2014) (blue) with the blastwave feedback model. The empty symbols correspond observations of the CGM around a sample of L < 0.1 L_* dwarf galaxies (empty stars Prochaska et al. 2011), COS-Halos and COS-Dwarfs galaxies (empty circles Bordoloi et al. 2014), nearby faint dwarf galaxies (empty squares Burchett et al. 2016), star-forming field dwarf galaxies (empty diamonds Johnson et al. 2017), and the low-mass dwarf galaxy WLM (empty pentagon Zheng et al. 2019).
