Large-scale dual AGN in large-scale cosmological hydrodynamical simulations
Clara Puerto-Sánchez, Melanie Habouzit, Marta Volonteri +10
Detecting dual active galactic nuclei (DAGN) in observations and understanding theoretically which massive black holes (MBHs) compose them and in which galactic and large-scale env…
Robust Field-level Likelihood-free Inference with Galaxies
Natalí S. M. de Santi, Helen Shao, Francisco Villaescusa-Navarro +12
We train graph neural networks to perform field-level likelihood-free inference using galaxy catalogs from state-of-the-art hydrodynamic simulations of the CAMELS project. Our mode…
Inferring the impact of feedback on the matter distribution using the Sunyaev Zel'dovich effect: Insights from CAMELS simulations and ACT+DES data
Shivam Pandey, Kai Lehman, Eric J. Baxter +6
Feedback from active galactic nuclei and stellar processes changes the matter distribution on small scales, leading to significant systematic uncertainty in weak lensing constraint…
The SZ flux-mass (-) relation at low halo masses: improvements with symbolic regression and strong constraints on baryonic feedback
Digvijay Wadekar, Leander Thiele, J. Colin Hill +8
Feedback from active galactic nuclei (AGN) and supernovae can affect measurements of integrated SZ flux of halos () from CMB surveys, and cause its relation with the…
Breaking baryon-cosmology degeneracy with the electron density power spectrum
Andrina Nicola, Francisco Villaescusa-Navarro, David N. Spergel +8
Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that ar…
Cosmology with one galaxy?
Francisco Villaescusa-Navarro, Jupiter Ding, Shy Genel +10
Galaxies can be characterized by many internal properties such as stellar mass, gas metallicity, and star-formation rate. We quantify the amount of cosmological and astrophysical i…
