Observational Evidence of Velocity Anisotropy Assembly Bias in Galaxy Clusters

Facundo Rodriguez, Andrea Biviano, Ravi K. Sheth +2

Cosmological simulations show that halo clustering depends on secondary internal properties beyond mass, an effect known as assembly bias. In particular, numerical models have show…

Aletheia: Emulating the halo mass function with evolution mapping

Andrea Fiorilli, Ariel G. Sánchez, Andrés N. Ruiz +1

We present an emulator of the halo mass function (HMF) based on Gaussian-process regression, that exploits the evolution mapping framework. This framework splits cosmological param…

The role of filaments in the large-scale conformity signal

Daniela Palma, Ivan Lacerna, Noelia Pérez +8

We investigate the large-scale conformity signal and its connection with the large-scale structure, focusing on low-mass central galaxies, after excluding galaxies that were satell…

Cluster-green galaxy correlations: where do these galaxies live?

Selene Levis, Facundo Rodriguez, Héctor J. Martínez +2

Green valley (GV) galaxies are thought to represent a transitional population between star-forming and quiescent systems. However, their spatial distribution relative to galaxy sys…

Halo Occupation Distribution estimation performance for LSST data

P. Cataldi, V. Cristiani, F. Rodriguez +4

Upcoming imaging surveys, such as the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), will enable high signal-to-noise measurements of galaxy clustering. The halo…

Evolution of submillimeter galaxies across cosmic-web environments

Ankit Kumar, M. Celeste Artale, Antonio D. Montero-Dorta +12

Submillimeter galaxies (SMGs) provide valuable insights into galaxy formation and evolution and are likely influenced by their cosmic environment. However, their rarity makes envir…

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…

Connecting clustering and the cosmic web:Observational constraints on secondary halo bias

Facundo Rodriguez, Antonio D. Montero-Dorta

Cosmological simulations predict significant secondary dependencies of halo clustering on internal properties and environment. Detecting these subtle signals in observational data…

Aletheia: Emulating the non-linear matter power spectrum in the context of evolution mapping

Ariel G. Sanchez, Andrés N. Ruiz, Facundo Rodriguez +7

We present Aletheia, a new emulator of the non-linear matter power spectrum, , built upon the evolution mapping framework. This framework addresses the limitations of traditi…

Galaxy-halo internal alignments across cosmic time

Agustina V. Marsengo-Colazo, Facundo Rodriguez, Manuel Merchán

Investigations of intrinsic alignments suggest a link between the alignment of a central galaxy's major axis with the galaxy distribution and its internal galaxy-halo shape alignme…

The invariance of group occupation across the cosmic web

Vicente Izzo Dominguez, Facundo Rodriguez, Antonio D. Montero-Dorta

Recent efforts to identify secondary variations in the Halo Occupation Distribution (HOD) have primarily focused on simulations examining the role of large-scale cosmic environment…

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…

The evolution of low-mass central galaxies in the vicinity of massive structures and its impact on the two-halo conformity

Daniela Palma, Ivan Lacerna, M. Celeste Artale +7

We investigated the population of low-mass central galaxies with Mstar = Msun/h, inhabiting regions near massive groups and clusters of galaxies using the TNG300…

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…

Star Formation and Dust in the Cosmic Web

Massimiliano Parente, Cinthia Ragone-Figueroa, Pablo López +8

The large-scale environment of the cosmic web is believed to impact galaxy evolution, but there is still no consensus regarding the mechanisms. We use a semi-analytic model (SAM) g…

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…
