Gravo-thermal properties and formation of elliptical galaxies
I. Marquez, G. B. Lima Neto, H. Capelato +2
We have analyzed a sample of galaxies belonging to three clusters: Coma, Abell 85, and Abell 496 (real galaxies) and a sample of simulated elliptical galaxies formed in a hierarchi…
Circumnuclear structure and kinematics in the active galaxy NGC 6951
Enrique Perez, Isabel Marquez, Ignacio Marrero +5
A study is presented of the central structure and kinematics of the galaxy NGC 6951, by means of broad band B'IJK images and high resolution high dispersion longslit spectroscopy,…
Restarting activity in the giant radio galaxy J1835+620
L. Lara, I. Marquez, W. D. Cotton +4
We present radio and optical observations of the peculiar radio galaxy J1835+620, a member of a new sample of large angular size radio galaxies selected from the NRAO VLA Sky Surve…
Effects of interaction on the properties of spiral galaxies. II. Isolated galaxies: The zero point
I. Marquez, M. Moles
We analyse the properties of a sample of 22 bright isolated spiral galaxies on the basis of Johnson B,V,I images and optical rotation curves. The fraction of early morphological ty…
