Massive Clumps in Local Galaxies: Comparisons with High-Redshift Clumps
Bruce G. Elmegreen, Debra Meloy Elmegreen, Jorge Sanchez Almeida +5
Local UV-bright galaxies in the Kiso survey include clumpy systems with kpc-size star complexes that resemble clumpy young galaxies in surveys at high redshift. We compare clump ma…
Qualitative interpretation of galaxy spectra
J. Sanchez Almeida, R. Terlevich, E. Terlevich +2
We describe a simple step-by-step guide to qualitative interpretation of galaxy spectra. Rather than an alternative to existing automated tools, it is put forward as an instrument…
Relationship between Hubble type and spectroscopic class in local galaxies
J. Sanchez Almeida, J. A. L. Aguerri, C. Munoz-Tunon +1
We compare the Hubble type and the spectroscopic class of the galaxies with spectra in SDSS/DR7. As it is long known, elliptical galaxies tend to be red whereas spiral galaxies ten…
Automatic unsupervised classification of all SDSS/DR7 galaxy spectra
J. Sanchez Almeida, J. A. L. Aguerri, C. Munoz-Tunon +1
Using the 'k-means' cluster analysis algorithm, we carry out an unsupervised classification of all galaxy spectra in the seventh and final Sloan Digital Sky Survey data release (SD…
