BIND (Baryonic INpainting with Deep learning): A Field-level Emulator for Galaxy Groups and Clusters
Max E. Lee, Shy Genel, Zoltan Haiman +3
Baryonic feedback is a dominant source of systematic uncertainty for upcoming weak-lensing surveys, but current tools for modeling its effect rely on spherical approximations and d…
ELGLRG distribution through dark matter halo dynamics
Ginevra Favole, Francisco-Shu Kitaura, Boryana Hadzhiyska +3
We investigate the clustering and halo occupation distribution (HOD) of DESI Y1 emission-line (ELGs) and luminous red (LRGs) galaxies at , including their cross-correlat…
Backlighting extended gas halos around luminous red galaxies: kinematic Sunyaev-Zel'dovich effect from DESI Y1 x ACT
Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska +58
The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-…
The relationship between galaxy size and halo properties: Insights from the IllustrisTNG simulations and differential clustering
Rachel S. Somerville, Austen Gabrielpillai, Boryana Hadzhiyska +1
The physical origin of the radial sizes of galaxies and how galaxy sizes are correlated with the properties of their host dark matter halos is an open question in galaxy formation.…
Dark Sage: Next-generation semi-analytic galaxy evolution with multidimensional structure and minimal free parameters
Adam R. H. Stevens, Manodeep Sinha, Alexander Rohl +4
After more than five years of development, we present a new version of Dark Sage, a semi-analytic model (SAM) of galaxy formation that breaks the mould for models of its kind. Incl…
The MillenniumTNG Project: Inferring cosmology from galaxy clustering with accelerated N-body scaling and subhalo abundance matching
Sergio Contreras, Raul E. Angulo, Volker Springel +11
We introduce a novel technique for constraining cosmological parameters and galaxy assembly bias using non-linear redshift-space clustering of galaxies. We scale cosmological N-bod…
The MillenniumTNG Project: The galaxy population at
Rahul Kannan, Volker Springel, Lars Hernquist +11
The early release science results from have yielded an unexpected abundance of high-redshift luminous galaxies that seems to be in tension with current theories of…
The galaxy-halo connection of emission-line galaxies in IllustrisTNG
Boryana Hadzhiyska, Sandro Tacchella, Sownak Bose +1
We employ the hydrodynamical simulation IllustrisTNG-300-1 to explore the halo occupation distribution (HOD) and environmental dependence of luminous star-forming emission-line gal…
