Fossil groups origins II. Unveiling the formation of the brightest group galaxies through their scaling relations
J. Mendez-Abreu, J. A. L. Aguerri, R. Barrena +11
(Abridged) Fossil systems are galaxy associations dominated by a relatively isolated, bright elliptical galaxy, surrounded by a group of smaller galaxies lacking L* objects. We ana…
AVOCADO: A Virtual Observatory Census to Address Dwarfs Origins
R. Sanchez-Janssen, R. Amorin, M. Garcia-Vargas +9
Dwarf galaxies are by far the most abundant of all galaxy types, yet their properties are still poorly understood -especially due to the observational challenge that their intrinsi…
Fossil Groups Origins: I. RX J105453.3+552102 a very massive and relaxed system at z~0.5
J. A. L. Aguerri, M. Girardi, W. Boschin +11
The most accepted scenario for the origin of fossil groups (FGs) is that they are galaxy associations in which the merging rate was fast and efficient. These systems have assembled…
Surprises in Image Decomposition of Edge-on Galaxies: does Sombrero have a (classical) bulge?
Dimitri A. Gadotti, Rubén Sánchez-Janssen
The spheroid of the Sombrero galaxy, NGC 4594, is considered a prototype of classical, merger-built bulges. We use a Spitzer, IRAC 3.6 micron image to perform a detailed structural…
