Galaxy bias renormalization: Two-loop Power Spectrum, One-loop Trispectrum and Bispectrum
Thomas Bakx, Mathias Garny, Henrique Rubira +1
We present a complete treatment of fifth-order renormalized galaxy bias at the one- and two-loop level in real space, including gradient corrections to deterministic bias operators…
Tidal alignment and tidal torquing modeling for the cosmic shear three-point correlation function and mass aperture skewness
Rafael C. H. Gomes, Kyle Miller, Sunao Sugiyama +3
We present a model for the intrinsic alignment contamination of the shear three-point correlation function and skewness of the mass aperture statistic using the tidal alignment and…
Three-point intrinsic alignments of galaxies and haloes in the FLAMINGO simulations
Casper Vedder, Thomas Bakx, Nora Elisa Chisari +2
Third-order statistics provide information beyond two-point measures, but extracting this information requires accurate and consistent modelling. We measure and detect the three-po…
Rapid cosmological inference with the two-loop matter power spectrum
Thomas Bakx, Henrique Rubira, Nora Elisa Chisari +1
We compute the two-loop effective field theory (EFT) power spectrum of dark matter density fluctuations in CDM using the recently proposed COBRA method (Bakx. et al, 2025). With…
One-Loop Galaxy Bispectrum: Consistent Theory, Efficient Analysis with COBRA, and Implications for Cosmological Parameters
Thomas Bakx, Mikhail M. Ivanov, Oliver H. E. Philcox +1
We present an efficient and accurate pipeline for the analysis of the redshift-space galaxy bispectrum multipoles at one-loop order in effective field theory (EFT). We provide a sy…
Two-loop renormalization and running of galaxy bias
Thomas Bakx, Mathias Garny, Henrique Rubira +1
We systematically extend the framework of galaxy bias renormalization to two-loop order. For the minimal complete basis of 29 deterministic bias operators up to fifth order in the…
The Bispectrum of Intrinsic Alignments: II. Precision Comparison Against Dark Matter Simulations
Thomas Bakx, Toshiki Kurita, Alexander Eggemeier +2
We measure three-dimensional bispectra of halo intrinsic alignments (IA) and dark matter overdensities in real space from N-body simulations for halos of mass $10^{12}-10^{12.5} M_…
The Bispectrum of Intrinsic Alignments: Theory Modelling and Forecasts for Stage IV Galaxy Surveys
Thomas Bakx, Alexander Eggemeier, Toshiki Kurita +2
We present a complete treatment of the bispectrum of intrinsic alignments, both in three spatial dimensions and in projection in the flat-sky approximation. Since intrinsic alignme…
COBRA: Optimal Factorization of Cosmological Observables
Thomas Bakx, Nora Elisa Chisari, Zvonimir Vlah
We introduce COBRA (Cosmology with Optimally factorized Bases of Radial Approximants), a novel framework for rapid computation of large-scale structure observables. COBRA separates…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Surveying the distant Universe
Eelco van Kampen, Tom Bakx, Carlos De Breuck +27
During the most active period of star formation in galaxies, which occurs in the redshift range 1<z<3, strong bursts of star formation result in significant quantities of dust, whi…
B-modes from galaxy cluster alignments in future surveys
Christos Georgiou, Thomas Bakx, Juliard van Donkersgoed +1
Intrinsic alignment (IA) of source galaxies represents an important contaminant for upcoming cosmic shear surveys. In particular, it is expected on general grounds that IA contains…
Probing Ultra-late Reionization: Direct Measurements of the Mean Free Path over
Yongda Zhu, George D. Becker, Holly M. Christenson +22
The mean free path of ionizing photons, , is a critical parameter for modeling the intergalactic medium (IGM) both during and after reionization. We present direct mea…
HYMALAIA: A Hybrid Lagrangian Model for Intrinsic Alignments
Francisco Maion, Raul E. Angulo, Thomas Bakx +3
The intrinsic alignment of galaxies is an important ingredient for modelling weak-lensing measurements, and a potentially valuable cosmological and astrophysical signal. In this pa…
Effective Field Theory of Intrinsic Alignments at One Loop Order: a Comparison to Dark Matter Simulations
Thomas Bakx, Toshiki Kurita, Nora Elisa Chisari +2
We test the regime of validity of the effective field theory (EFT) of intrinsic alignments (IA) at the one-loop level by comparing with 3D halo shape statistics in N-body simulatio…
Close-up view of a luminous star-forming galaxy at z=2.95
S. Berta, A. J. Young, P. Cox +35
(Abridged) Exploiting the sensitivity and broad band width of NOEMA, we have studied the molecular gas and dust in the galaxy HerBS-89a, at z=2.95. High angular resolution images r…
