Cluster connectivity in DES Y3 data: impact on galaxy properties
C. Gouin, C. Laigle, J. Prat +4
Connectivity, namely the number of cosmic filaments reaching out of groups or clusters, has recently emerged as an informative way to quantify environment. With the advent of wide-…
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…
Simba Simulation: The Effect of Feedback Physics on Matter Distribution in the Cosmic Web
Chenze Dong, Florian Dedieu, Daniela Galárraga-Espinosa +3
The discrepancy between the early-time estimation and late-time observation on the cosmic baryon content - the 'missing baryon problem' - is a longstanding problem in cosmology. Al…
Impact of the large-scale cosmic web on the X-ray emitting circumgalactic medium
Soumya Shreeram, Daniela Galárraga-Espinosa, Johan Comparat +9
The hot circumgalactic medium (CGM), probed by X-ray observations, plays a central role in understanding gas flows that drive a galaxy's evolution. While CGM properties have been w…
Unveiling the small-scale web around galaxies with miniJPAS and DESI
Daniela Galárraga-Espinosa, Guinevere Kauffmann, Silvia Bonoli +23
We present the first statistical observational study detecting filaments in the immediate surroundings of galaxies, i.e. the local web of galaxies. Simulations predict that cold ga…
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…
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…
Pearls on a string: Dark and bright galaxies on a strikingly straight and narrow filament
Maryam Arabsalmani, Sambit Roychowdhury, Benjamin Schneider +11
We identify a chain of galaxies along an almost straight line in the nearby Universe with a projected length of ~5 Mpc. The galaxies are distributed within projected distances of o…
The Environmental Dependence of the Stellar Mass - Gas Metallicity Relation in Horizon Run 5
Aaron R. Rowntree, Ankit Singh, Fiorenzo Vincenzo +11
Metallicity offers a unique window into the baryonic history of the cosmos, being instrumental in probing evolutionary processes in galaxies between different cosmic environments.…
Evolution of cosmic filaments in the MTNG simulation
Daniela Galárraga-Espinosa, Corentin Cadiou, Céline Gouin +11
We present a study of the evolution of cosmic filaments across redshift with an emphasis on some important properties: filament lengths, growth rates, and radial profiles of galaxy…
The thesan project: public data release of radiation-hydrodynamic simulations matching reionization-era JWST observations
Enrico Garaldi, Rahul Kannan, Aaron Smith +13
Cosmological simulations serve as invaluable tools for understanding the Universe. However, the technical complexity and substantial computational resources required to generate su…
Flows around galaxies. I. The dependency of galaxy connectivity on cosmic environments and effects on the star-formation rate
Daniela Galárraga-Espinosa, Enrico Garaldi, Guinevere Kauffmann
With the aim of bringing substantial insight to the fundamental question of how galaxies acquire their material for star-formation, we present the first comprehensive characterisat…
On the relative effect of nodes and filaments of the cosmic web on the quenching of galaxies and the orientation of their spin
Nicola Malavasi, Mathieu Langer, Nabila Aghanim +2
Filaments and clusters of the cosmic web have an impact on the properties of galaxies, switching off their star-formation, contributing to the build-up of their stellar mass, and i…
Relative distribution of dark matter, gas, and stars around cosmic filaments in the IllustrisTNG simulation
Daniela Galárraga-Espinosa, Mathieu Langer, Nabila Aghanim
We present a comprehensive study of the distribution of matter around different populations of large-scale cosmic filaments, using the IllustrisTNG simulation at z=0. We computed t…
Properties of gas phases around cosmic filaments at z=0 in the Illustris-TNG simulation
Daniela Galárraga-Espinosa, Nabila Aghanim, Mathieu Langer +1
We present the study of gas phases around cosmic-web filaments detected in the TNG300-1 hydro-dynamical simulation at redshift z=0. We separate the gas in five different phases acc…
Populations of filaments from the distribution of galaxies in numerical simulations
Daniela Galárraga-Espinosa, Nabila Aghanim, Mathieu Langer +2
We present a statistical study of the filamentary structures of the cosmic web in the large hydro-dynamical simulations Illustris-TNG, Illustris, and Magneticum at redshift z=0. We…
