Tracing Galaxy Bias Through the Cosmic Web: The Role of Filaments
Constanza A. Soto-Suárez, Antonio D. Montero-Dorta, Daniela Galárraga-Espinosa +4
The large-scale clustering of galaxies depends not only on their internal properties but also on their location within the cosmic web, which defines the anisotropic environments wh…
The VariableTNG project: Unveiling the physical drivers of galaxy quenching
Ignacio G. Alfaro, Antonio D. Montero-Dorta, Hong Guo +4
Understanding the physical processes that regulate galaxy quenching is a key challenge in galaxy formation and evolution. The VariableTNG (VTNG) project provides a laboratory to in…
The Galaxy Bias Profile of Cosmic Voids:A Comparison of Void Finders
Ignacio G. Alfaro, Antonio D. Montero-Dorta, Jorge F. Bustillos +6
Cosmic voids, the largest underdense regions in the Universe, provide unique laboratories for studying galaxy formation and constitute powerful probes of cosmology. Recent work has…
The evolution of the halo occupation distribution in cosmic voids
Ignacio G. Alfaro, Facundo Rodriguez, Andrés N. Ruiz
The halo occupation distribution is a cornerstone in understanding galaxy formation within the large-scale structure.On the other hand, in the context of the large-scale structure…
The galaxy bias profile of cosmic voids
Antonio D. Montero-Dorta, Andrés Balaguera-Antolínez, Ignacio G. Alfaro +7
Cosmic voids are underdense regions within the large-scale structure of the Universe, spanning a wide range of physical scales - from a few megaparsecs (Mpc) to the largest observa…
Evolution of HOD and galaxy properties in filaments and nodes of the cosmic web
Noelia R. Perez, Luis A. Pereyra, Georgina Coldwell +2
We study the evolution of the Halo Occupation Distribution (HOD) and galaxy properties of nodes and filamentary structures obtained by \textsc{DisPerSE} from the \textsc{Illustris…
Characterising HOD in filaments and nodes of the cosmic web
Noelia R. Perez, Luis A. Pereyra, Georgina Coldwell +3
The standard paradigm for the formation of the Universe suggests that large structures are formed from hierarchical clustering by the continuous accretion of less massive galaxy sy…
How do galaxies populate halos in extreme density environments? An analysis of the Halo Occupation Distribution in SDSS
Ignacio G. Alfaro, Facundo Rodriguez, Andrés N. Ruiz +2
Recent works have shown that the properties of galaxy populations in dark matter halos vary with large-scale environments. These results suggest a variation in the halo occupation…
Galaxy populations in haloes in high-density environments
Ignacio G. Alfaro, Andres N. Ruiz, Heliana E. Luparello +2
There are hints suggesting that properties of galaxy populations in dark matter haloes may depend on their large-scale environment. Recent works point out that very low-density env…
How galaxies populate haloes in very low-density environments? An analysis of the Halo Occupation Distribution in cosmic voids
Ignacio. G. Alfaro, Facundo Rodriguez, Andrés N. Ruiz +1
Evidence shows properties of dark matter haloes may vary with large-scale environment. By studying the halo occupation distribution in cosmic voids it is possible to obtain useful…
Structure and dynamics in low density regions: galaxy-galaxy correlations inside cosmic voids
Andrés N. Ruiz, Ignacio G. Alfaro, Diego Garcia Lambas
We compute the galaxy-galaxy correlation function of low-luminosity SDSS-DR7 galaxies inside cosmic voids identified in a volume limited s…
