The 6dF Galaxy Survey provides a very large sample of galaxies with reliable measurements of Lick line indices and velocity dispersions. This sample can be used to explore the correlations between mass and stellar population parameters such as age, metallicity and [α/Fe]. Preliminary results from such an analysis are presented here, and show that age and(More)
We present an analysis of the stellar populations as a function of mass in a sample of ∼7000 galaxies of all morphological and emission types from the 6dF Galaxy Survey (6dFGS). We measure velocity dispersions and Lick indices from the spectra of the central regions of these galaxies, deriving ages and metallicities from the Lick indices using stellar(More)
The object of this paper is to evaluate the marginal filtration occurring between restoration/teeth in cavities filled with silver alloy when using different cavity varnish and adhesives. In 50 teeth removed as a result of decay, cavities were prepaired on vestibular faces and were divided into 5 equal groups: Group A: with no caviti varnish; Group B: two(More)
We used observations from the Giant Metrewave Radio Telescope to measure the atomic hydrogen gas content of 324 galaxies around the galaxy cluster Abell 370 at a redshift of z = 0.37 (a look-back time of ∼4 billion years). The Hi 21-cm emission from these galaxies was measured by coadding their signals using precise optical redshifts obtained with the(More)
