Central galaxy alignments. Dependence on the mass and the large-scale environment
Facundo Rodriguez, Manuel Merchán, Daniela Galárraga-Espinosa +4
Observations indicate that central galaxies show a significant alignment of their main shape axes with other galaxies in their group, as well as with the large-scale structure of t…
Structure and large scale environment of galaxy pairs in the S-PLUS DR4
M. C. Cerdosino, A. L. O'Mill, F. Rodriguez +8
In this paper, we use photometric data from the S-PLUS DR4 survey to identify isolated galaxy pairs and analyse their characteristics and properties. Our results align with previou…
The dependence of assembly bias on the cosmic web
Antonio D. Montero-Dorta, Facundo Rodriguez
For low-mass haloes, the physical origins of halo assembly bias have been linked to the slowdown of accretion due to tidal forces, which are expected to be more dominant in some co…
The PAU Survey: Close galaxy pairs identification and analysis
E. J. Gonzalez, F. Rodriguez, D. Navarro-Gironés +18
Galaxy pairs constitute the initial building blocks of galaxy evolution, which is driven through merger events and interactions. Thus, the analysis of these systems can be valuable…
Tracking the evolution of satellite galaxies: mass stripping and dark-matter deficient galaxies
Antonio D. Montero-Dorta, Facundo Rodriguez, M. Celeste Artale +2
Satellite galaxies undergo a variety of physical processes when they are accreted by groups and clusters, often resulting in the loss of baryonic and dark matter (DM) mass. In this…
Local and large-scale effects on the astrophysics of void-galaxies
Agustín M. Rodríguez-Medrano, Dante J. Paz, Federico A. Stasyszyn +3
Galaxies in cosmic voids have been reported with properties related to a delayed evolution with respect to the Universe in general. These characteristics reflect the interaction of…
Alignment of the central galaxies with the environment
Facundo Rodriguez, Manuel Merchán, M. Celeste Artale
In this work, we combine ellipticity and major axis position angle measurements from the Sloan Digital Sky Server Data Release 16 (SDSS DR16) with the group finder algorithm of Rod…
On the environmental influence of groups and clusters of galaxies beyond the virial radius: Galactic conformity at few Mpc scales
Ivan Lacerna, Facundo Rodriguez, Antonio D. Montero-Dorta +6
The environment within dark matter haloes can quench the star formation of galaxies. However, environmental effects beyond the virial radius of haloes ( 1 Mpc) are less ev…
The galaxy size - halo mass scaling relations and clustering properties of central and satellite galaxies
Facundo Rodriguez, Antonio D. Montero-Dorta, Raul E. Angulo +2
In this work, we combine size and stellar mass measurements from the Sloan Digital Sky Server (SDSS) with the group finder algorithm of Rodriguez \& Merchán in order to determine t…
Close galaxy pairs with accurate photometric redshifts
Facundo Rodriguez, Elizabeth J. Gonzalez, Ana L. O'Mill +5
Context. Studies of galaxy pairs can provide valuable information to jointly understand the formation and evolution of galaxies and galaxy groups. Consequently, taking into account…
The manifestation of secondary halo bias on the galaxy population from IllustrisTNG300
Antonio D. Montero-Dorta, M. Celeste Artale, L. Raul Abramo +6
We use the improved IllustrisTNG300 magneto-hydrodynamical cosmological simulation to revisit the effect that secondary halo bias has on the clustering of the central galaxy popula…
Weak lensing analysis of galaxy pairs using CS82 data
Elizabeth J. Gonzalez, Facundo Rodriguez, Diego García Lambas +6
In this work we analyze a sample of close galaxy pairs (relative projected separation kpc and relative radial velocities km s) using a weak lensing analy…
Taking advantage of photometric galaxy catalogues to determine the halo occupation distribution
Facundo Rodriguez, Manuel Merchán, Mario Agustín Sgró
Context. Halo occupation distribution (HOD) is a powerful statistic that allows the study of several aspects of the matter distribution in the Universe, such as evaluating semi-ana…
