PROPERTIES OF SATELLITE GALAXIES IN THE SDSS PHOTOMETRIC SURVEY: LUMINOSITIES, COLORS, AND PROJECTED NUMBER DENSITY PROFILES
- M. Lares, D. G. Lambas, M. Domínguez
- Physics
- 23 November 2010
We analyze photometric data in the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) to infer statistical properties of faint satellites associated with isolated bright galaxies (M{sub r} < -20.5)… Expand
The faint-end of the galaxy luminosity function in groups
- Raul Ernesto Gonzalez, M. Lares, D. G. Lambas, C. Valotto
- Physics
- 6 July 2005
We compute the galaxy luminosity function in spectroscopically selected nearby groups and clusters. Our sample comprises 728 systems extracted from the third release of the Sloan Digital Sky Survey… Expand
Clues on void evolution – I. Large-scale galaxy distributions around voids
- L. Ceccarelli, D. Paz, M. Lares, N. Padilla, D. G. Lambas
- Physics
- 24 June 2013
We perform a statistical study focused on void environments. We examine galaxy density profiles around voids in the SDSS, finding a correlation betwe en void‐centric distance to the shell of maximum… Expand

Future virialized structures: an analysis of superstructures in the SDSS-DR7
- H. E. Luparello, M. Lares, D. G. Lambas, N. Padilla
- Physics
- 10 January 2011
We construct catalogues of present superstructures that, according to a A cold dark matter (∧CDM) scenario, will evolve into isolated, virialized structures in the future. We use a smoothed… Expand
Catalogue of Large Magellanic Cloud star clusters observed in the Washington photometric system
- T. Palma, L. Gramajo, J. Clària, M. Lares, D. Geisler, A. Ahumada
- Physics
- 17 November 2015
Aims. The main goal of this study is to compile a catalogue including the fundamental parameters of a complete sample of 277 star clusters (SCs) of the Large Magellanic Cloud (LMC) observed in the… Expand
Voids and superstructures: correlations and induced large-scale velocity flows
- M. Lares, Haliana Luparello, +4 authors D. G. Lambas
- Physics
- 18 May 2017
The expanding complex pattern of filaments, walls and voids build the evolving cosmic web with material flowing from underdense onto high density regions. Here we explore the dynamical behaviour of… Expand
PRESENTACION ORAL Multi-modal DEM in the solar corona
Differential emission measure tomography (DEMT) uses time series of coronal EUV images covering a full solar rotation to determine the three-dimensional (3D) distribution of the local differential… Expand
