A new approach in data reduction: proper handling of random errors and image distortions
N. Cardiel, J. Gorgas, J. Gallego +5
Data reduction procedures are aimed to minimize the impact of data acquisition imperfections on the measurement of data properties with a scientific meaning for the astronomer. To…
Stellar populations in bulges of spiral galaxies
P. Jablonka
We discuss the integrated properties of the stellar population in bulges along the Hubble sequence and new HST data for individual stars in the bulge of M31.
Line-Strength Gradients in Cooling Flow Galaxies
N. Cardiel, J. Gorgas, A. Aragon-Salamanca
We present new results on line-strength gradients in a sample of 18 brightest cluster galaxies (13 in clusters with cooling flows and 5 in clusters without). Here we focus on the s…
Spectroscopic Gradients in Elliptical Galaxies
J. Jesus Gonzalez, Javier Gorgas
Preliminary results based on a large compilation of line-strength profiles are presented and discussed. Elliptical galaxies (Es) with strong central Mg show steeper line-streng…
