Near-IR line-strengths in elliptical galaxies: evidence for IMF variations?
A. J. Cenarro, J. Gorgas, A. Vazdekis +2
We present new relations between recently defined line-strength indices in the near-IR (CaT*, CaT, PaT, MgI, and sTiO) and central velocity dispersion (sigma_0) for a sample of 35…
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…
Evidence of fast rotation in dwarf elliptical galaxies
S. Pedraz, J. Gorgas, N. Cardiel +2
In this Paper we investigate the kinematical properties of early-type dwarfs by significantly enlarging the scarce observational sample so far available. We present rotation curves…
Stellar Populations in Bulges of Spiral Galaxies
P. Jablonka, J. Gorgas, P. Goudfrooij
We have conducted a spectroscopic analysis of the bulges of a sample of 31 spiral galaxies, spanning the Hubble sequence from S0 to Scd type, in order to study the radial distribut…
