| Description | In researching my Arp talk, I downloaded and read Vera Rubin's classic paper published in 1980 where she measured the rotation curves of 21 spiral galaxies ("Sc" or "Sbc" in the Hubble system) and hypothesized the existence of Dark Matter. She found "Neither high nor low luminosity Sc galaxies have falling rotation curves. Sc galaxies of all luminosities must have significant mass located beyond the optical image." This galaxy has been the subject of research in conjunction with NGC 1052-DF4, which was originally hypothesized to have been stripped of dark matter by NGC 1035. Amusingly this is disputed based on yet more follow-on observations. Still, NGC 1035 appears to be writing a new chapter in the search for proof of the existence of Dark Matter beyond its seminal role in the observations that triggered Dark Matter in the first place. Or, possibly, play a role in demonstrating the dark matter doesn't exist. |
