We test the hypothesis that the velocity eld derived from Tully-Fisher measurements of spiral galaxies, and that derived independently from D n-measurements of ellipticals and S0s, are noisy versions of the same underlying velocity eld. The radial velocity elds are derived using tensor Gaussian smoothing of radius 1200 km s 1. They are compared at grid points near which the sampling by both typ...
متن کاملThe Evolution of Ellipticals, Spirals and Irregulars: Overcoming Selection Bias
The Hubble Deep Fields represent our best opportunity for probing galaxy evolution over a substantive look-back time. However as with any dataset the HDFs are prone to selection biases. These biases are extremely severe beyond z ∼ 1.25 such that a meaningful interpretation of generic galaxy evolution is not possible. We can however extract well defined volume-limited samples at z < 1. The data ...
متن کاملThe Globular Cluster Systems of Ellipticals and Spirals
In this overview of the key properties of globular cluster (GC) systems I show that the GCs in elliptical and spiral host galaxies have more in common than previously thought. After contrasting these properties I briefly comment on GC formation. 1. Spatial Distribution For the Milky Way (Minniti 1995) and other spiral galaxies (Forbes, Brodie & Larsen 2001) a consenus is emerging that the bulk ...
متن کاملA Sample of Field Ellipticals
Using well-defined selection criteria applied to the LEDA galaxy catalogue we have constructed a sample of elliptical galaxies that can be taken to lie in the field. Such criteria can easily be applied to theoretical simulations for direct comparison with observations. The variation of the number of ‘isolated’ ellipticals with selection criteria is also investigated. A preliminary study of the ...
متن کاملA near Infrared Photometric Plane for Ellipticals and Bulges of Spirals
We report the existence of a single plane in the space of global photometric parameters describing elliptical galaxies and the bulges of early type spiral galaxies. The three parameters which define the plane are obtained by fitting the Sersic form to the brightness distribution obtained from near-infrared K band images. We find, from the range covered by their shape parameters, that the ellipt...
