Simulating MOS science on the ELT: Ly forest tomography
J. Japelj, C. Laigle, M. Puech +14
Mapping of the large-scale structure through cosmic time has numerous applications in the studies of cosmology and galaxy evolution. At , the structure can be traced by the…
Star-gas misalignment in galaxies: I. The properties of galaxies from the Horizon-AGN simulation and comparisons to SAMI
Donghyeon J. Khim, Sukyoung K. Yi, Yohan Dubois +12
Recent integral field spectroscopy observations have found that about 11% of galaxies show star-gas misalignment. The misalignment possibly results from external effects such as ga…
Comparing Galaxy Clustering in Horizon-AGN Simulated Lightcone Mocks and VIDEO Observations
Peter Hatfield, Clotilde Laigle, Matt Jarvis +5
Hydrodynamical cosmological simulations have recently made great advances in reproducing galaxy mass assembly over cosmic time - as often quantified from the comparison of their pr…
The impact of the connectivity of the cosmic web on the physical properties of galaxies at its nodes
Katarina Kraljic, Christophe Pichon, Sandrine Codis +11
We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We co…
The SAMI Galaxy Survey: First detection of a transition in spin orientation with respect to cosmic filaments in the stellar kinematics of galaxies
C. Welker, J. Bland-Hawthorn, J. Van de Sande +16
We present the first detection of mass dependent galactic spin alignments with local cosmic filaments with over 2 sigma confidence using IFS kinematics. The 3D network of cosmic fi…
Massive spheroids can form in single minor mergers
R. A. Jackson, G. Martin, S. Kaviraj +4
Understanding how rotationally-supported discs transform into dispersion-dominated spheroids is central to our comprehension of galaxy evolution. Morphological transformation is la…
From Stellar Halos to Intracluster Light: the physics of the Intra-Halo Stellar Component in cosmological hydrodynamical simulations
Rodrigo Cañas, Claudia del P. Lagos, Pascal J. Elahi +4
We study the Intra-Halo Stellar Component (IHSC) of Milky Way-mass systems up to galaxy clusters in the Horizon-AGN cosmological hydrodynamical simulation. We identify the IHSC usi…
And yet it flips: connecting galactic spin and the cosmic web
Katarina Kraljic, Romeel Dave, Christophe Pichon
We study the spin alignment of galaxies and halos with respect to filaments and walls of the cosmic web, identified with DisPerSE, using the SIMBA simulation from z=0-2. Massive ha…
Horizon-AGN virtual observatory -- 2: Template-free estimates of galaxy properties from colours
Iary Davidzon, Clotilde Laigle, Peter L. Capak +11
Using the Horizon-AGN hydrodynamical simulation and self-organising maps (SOMs), we show how to compress the complex data structure of a cosmological simulation into a 2-d grid whi…
New Horizon: On the origin of the stellar disk and spheroid of field galaxies at
Min-Jung Park, Sukyoung K. Yi, Yohan Dubois +7
The origin of the disk and spheroid of galaxies has been a key open question in understanding their morphology. Using the high-resolution cosmological simulation, New Horizon, we e…
Group connectivity in COSMOS: a tracer of mass assembly history
E. Darragh-Ford, C. Laigle, G. Gozaliasl +11
Cosmic filaments are the channel through which galaxy groups assemble their mass. Cosmic connectivity, namely the number of filaments connected to a given group, is therefore expec…
The formation and evolution of low-surface-brightness galaxies
G. Martin, S. Kaviraj, C. Laigle +6
Our statistical understanding of galaxy evolution is fundamentally driven by objects that lie above the surface-brightness limits of current wide-area surveys (mu ~ 23 mag arcsec^-…
