Taking the bulge and disk components into account in our calculation of sigma(e) puts NGC 4594 squarely on the M-sigma relation. We also determine that NGC 4594 lies directly on the M-L relation.doi:10.1088/0004-637X/739/1/21Jardel, John R...
The X-ray investigation shows a hard (Γ = 1.89) and moderately absorbed (NH = 1.8 × 10 21 cm 2) nuclear source of 1.5 × 10 40 erg s 1 in the 2–10 keV band, surrounded by hot gas at a temperature of 0.6 keV. The bolometric nuclear luminosity is at least 200 times lower ...

In this elliptical galaxy, as in the bulge-dominated galaxies NGC 3115 and NGC 4594, halo dark matter is unimportant over a significant range in radius near the center.doi:10.1086/300313John KormendyRalf BenderAaron S. EvansDouglas Richstone...
