Misalignment of axes of dark matter aloes[edit]

According to this academic paper of Anton Smirnov et al.:

It was found that the angular momentum of the hot gas corona around galaxies, shock heated due to the falling of external gas into the dark matter’s potential well, is usually misaligned with that of their stellar disc (van den Bosch et al. 2002; Roškar et al. 2010; Velliscig et al. 2015; Stevens et al. 2017). When the hot coronal gas cools, it settles into the disc (Fall & Efstathiou 1980; Kereš et al. 2005) and contributes misaligned angular momentum to the disc, which results in the disc tilting (Debattista et al. 2015; Earp et al. 2019). Consequently, it was found that the principal axes of dark matter haloes in blue star-forming galaxies are generally misaligned with the principal axes of their discs (Yang et al. 2006; Wang et al. 2008).
