A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially…
PROPERTIES OF SATELLITE GALAXIES IN THE SDSS PHOTOMETRIC SURVEY: LUMINOSITIES, COLORS, AND PROJECTED NUMBER DENSITY PROFILES
- M. Lares, D. 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 (Mr < −20.5) in the…
The faint-end of the galaxy luminosity function in groups
- Raul Ernesto Gonzalez, M. Lares, D. 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…

Clues on void evolution – I. Large-scale galaxy distributions around voids
- L. Ceccarelli, D. Paz, M. Lares, N. Padilla, D. 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…

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…
Future virialized structures: an analysis of superstructures in the SDSS-DR7
- H. E. Luparello, M. Lares, D. 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…
