Formation and Cosmic Evolution of Elliptical Galaxies
J. A. de Freitas Pacheco, R. Michard, R. Mohayaee
A review of the present observational and theoretical status of elliptical galaxies is presented with the aim to clarify whether the monolithic or the hierarchical, is a more viabl…
Morphological classification and structural parameters for early-type galaxies in the Coma cluster
S. Andreon, E. Davoust, R. Michard +2
We present the results of an isophotal shape analysis of three samples of galaxies in the Coma cluster. Quantitative morphology, together with structural and photometric parameters…
Morphology of galaxies in the Coma cluster region down to M_B=-14.25. I. A catalog of 473 members
R. Michard, S. Andreon
This paper presents morphological type, membership, and U-V color for a sample of galaxies in the Coma cluster direction, complete down to M_B=-15.00 mag and extending down to M_B=…
New UBVRI colour distributions in E-type galaxies I.The data
T. P. Idiart, R. Michard, J. A. de Freitas Pacheco
New colour distributions have been derived from wide field UBVRI frames for 36 northern bright elliptical galaxies and a few lenticulars. The classical linear representations of co…
