NGC 755 is an emission line spiral galaxy in the constellation of Cetus. [1] [3] The galaxy's velocity of 1641.2 km/s was used to calculate its distance using the Tully–Fisher relation. [1] [2] Its dark matter halo was found to be core-dominated, in agreement with predictions from the lambda-CDM model of cosmology. [2]
