The Fundamental Plane of Early-Type Galaxies as a Confounding Correlation
Early-type galaxies are characterized by many scaling relations. One of them, the so-called fundamental plane is a relatively tight correlation between three variables, and has resisted a clear physical understanding despite many years of intensive research. Here, we show that the correlation between the three variables of the fundamental plane can be the artifact of the effect of another param...
متن کاملThe Sdss-ukidss Fundamental Plane of Early-type Galaxies
We derive the Fundamental Plane (FP) relation for a sample of 1430 early-type galaxies in the optical (r band) and the near-infrared (K band), by combining SDSS and UKIDSS data. With such a large, homogeneous dataset, we are able to assess the dependence of the FP on the waveband. Our analysis indicates that the FP of luminous early-type galaxies is essentially waveband independent, with its co...
متن کاملThe fundamental plane of isolated early-type galaxies
Here we present new measurements of effective radii, surface brightnesses and internal velocity dispersions for 23 isolated early-type galaxies. The photometric properties are derived from new multi-colour imaging of 10 galaxies, whereas the central kinematics for 7 galaxies are taken from forthcoming work by Hau & Forbes. These are supplemented with data from the literature. We reproduce the c...
متن کاملBulges on the Fundamental Plane of Early-Type Galaxies
In an ongoing effort to study the formation and evolution of galactic bulges we have investigated the position of 19 bulges of type S0-Sbc on the fundamental plane (FP). We find that bulges, both in B and K band, lie close to but slightly below the FP defined by ellipticals and S0s, i.e. are slightly brighter. There are hints that bulges of later morphological type are situated below the other ...
متن کاملThe tilt of the Fundamental Plane of Early - type galaxies : wavelength dependence . ⋆
The photometric parameters Re and μe of 74 early-type (E+S0+S0a) galaxies within 2 degrees projected radius from the Coma cluster centre are derived for the first time in the near IR H band (1.65 μm). These are used, coupled with measurements of the central velocity dispersion σ found in the literature, to determine the H band Fundamental Plane (FP) relation of this cluster: log Re ∝ A log σ + ...
