IIA study decodes the curious case of missing dark matter from distant galaxy

Indian Institute of Astrophysics researchers have revisited the ultra-diffuse galaxy, NGC 1052-DF2, challenging previous assumptions about its dark matter deficiency. The study suggests the galaxy possesses a 'cored' dark matter halo, unlike earlier 'cuspy' models. This new model indicates a more evenly spread dark matter distribution, potentially aligning NGC 1052-DF2 with standard galaxy formation theories.
