Active galactic nucleus jet feedback in hydrostatic halos
Rainer Weinberger, Kung-Yi Su, Kristian Ehlert +8
Feedback driven by jets from active galactic nuclei is believed to be responsible for reducing cooling flows in cool-core galaxy clusters. We use simulations to model feedback from…
The Stellar Chemical Abundances of Simulated Massive Galaxies at
Jee-Ho Kim, Sirio Belli, Rainer Weinberger
We analyze the stellar abundances of massive galaxies () at in the IllustrisTNG simulation with the goal of guiding the interpretation of current an…
Modeling globular clusters in the TNG50 simulation: predictions from dwarfs to giants
Jessica E. Doppel, Laura V. Sales, Dylan Nelson +9
We present a post-processing catalog of globular clusters (GCs) for the most massive groups and clusters in the TNG50 simulation of the IlllustrisTNG project (virial masses $M…
Unifying Sunyaev-Zel'dovich and X-ray predictions from clusters to galaxy groups: the impact of X-ray mass estimates on the scaling relation
Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai +7
One of the main limitations in precision cluster cosmology arises from systematic errors and uncertainties in estimating cluster masses. Using the Mock-X pipeline, we produce synth…
Sunyaev-Zel'dovich effect and X-ray scaling relations of galaxies, groups and clusters in the IllustrisTNG simulations
Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai +8
Observable thermodynamical properties of the intracluster medium (ICM) reflect the complex interplay between AGN feedback and the gravitational collapse of haloes. Using the large…
Probing the quasars in a universe with IllustrisTNG physics: Impact of gas-based black hole seeding models
Aklant Kumar Bhowmick, Laura Blecha, Yueying Ni +6
We explore implications of a range of black hole (BH) seeding prescriptions on the formation of the brightest quasars in cosmological hydrodynamic simulations. The unde…
Self-regulated AGN feedback of light jets in cool-core galaxy clusters
Kristian Ehlert, Rainer Weinberger, Christoph Pfrommer +2
Heating from active galactic nuclei (AGN) is thought to stabilize cool-core clusters, limiting star formation and cooling flows. We employ radiative magneto-hydrodynamic (MHD) simu…
Simulations of black hole fueling in isolated and merging galaxies with an explicit, multiphase ISM
Aneesh Sivasankaran, Laura Blecha, Paul Torrey +9
We study gas inflows onto supermassive black holes using hydrodynamics simulations of isolated galaxies and idealized galaxy mergers with an explicit, multiphase interstellar mediu…
Preferential Accretion and Circumbinary Disk Precession in Eccentric Binary Systems
Magdalena Siwek, Rainer Weinberger, Diego Munoz +1
We present a suite of high resolution hydrodynamic simulations of binaries immersed in circumbinary accretion disks (CBDs). For the first time, we investigate the preferential accr…
