A new family of distance indicator relations for elliptical galaxies

A physical distance indicator for spiral galaxies

In this paper we derive a Tully Fisher relation from measured I band photometry and Hα rotation curves of a large survey of southern sky spiral galaxies, obtained in Persic & Salucci (1995) by deprojecting and folding the raw Hα data of Mathewson, Ford & Buchhorn (1992). We calibrate the relation by combining several of the largest clusters in the survey, using an iterative maximum likelihood p...

Is the shape of the luminosity profile of dwarf elliptical galaxies a useful distance indicator?

The shape of the surface brightness profile of dE galaxies, quantified by parameter n of Sérsic’s generalized profile law, has recently been put forward as new extragalactic distance indicator (Young & Currie 1994). Its application to the Virgo cluster has subsequently led to the claim that the Virgo dEs are not lying in the cluster core but are distributed in a prolate structure stretching fro...

The Fundamental Scaling Relations of Elliptical Galaxies

We examine the fundamental scaling relations of elliptical galaxies formed through mergers. Using hundreds of simulations to judge the impact of progenitor galaxy properties on the properties of merger remnants, we find that gas dissipation provides an important contribution to tilt in the Fundamental Plane relation. Dissipationless mergers of disks produce remnants that occupy a plane similar ...
