The galaxy NGC1052–DF2, Dark Matter, and MOND
بهنام جوانمردی (پژوهشکده نجوم پژوهشگاه دانش های بنیادیIPM )
Abstract: The claims of van Dokkum et al. [1] that the dark matter content of the ultra diffuse galaxy NGC1052–DF2 is much less than expected (or even consistent with zero) has triggered a lot of excitements, but also serious debates, in the field. A galaxy without dark matter can potentially be a problem for alternative scenarios and modified gravity theories. In particular, van Dokkum et al. claimed that their measured properties of the NGC1052–DF2 is inconsistent with MOND. In a recently published paper [2], we showed they were wrong. In my talk, I will tell you the story of this exciting galaxy.
