Supermassive black holes in cosmological simulations I: MBH − M⋆ relation and black hole mass function [PDF]

Monthly notices of the Royal Astronomical Society, 2020
The past decade has seen significant progress in understanding galaxy formation and evolution using large-scale cosmological simulations. While these simulations produce galaxies in overall good agreement with observations, they employ different sub ...

Simulations of the Milky Way’s Central Molecular Zone – II. Star formation [PDF]

Monthly notices of the Royal Astronomical Society, 2020
The Milky Way’s Central Molecular Zone (CMZ) has emerged in recent years as a unique laboratory for the study of star formation. Here we use the simulations presented in Tress et al. to investigate star formation in the CMZ.

Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at z ≥ 10?

The Astrophysical Journal Letters, 2023
Recent photometric detections of extreme ( z > 10) redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation and in the most acute case, in tension with ΛCDM itself.

Galaxy Formation Theory [PDF]

, 2010
We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of baryonic material we describe the analytical and numerical

The overarching framework of core-collapse supernova explosions as revealed by 3D fornax simulations [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We have conducted 19 state-of-the-art 3D core-collapse supernova simulations spanning a broad range of progenitor masses. This is the largest collection of sophisticated 3D supernova simulations ever performed.

An Optimal Integral Controller for Adaptive Optics Systems

Sensors, 2023
Integral controllers are commonly employed in astronomical adaptive optics. This work presents a novel tuning procedure for integral controllers in adaptive optics systems which relies on information about the measured disturbances. This tuning procedure

Super-resolution emulator of cosmological simulations using deep physical models [PDF]

Monthly notices of the Royal Astronomical Society, 2020
We present an extension of our recently developed Wasserstein optimized model to emulate accurate high-resolution (HR) features from computationally cheaper low-resolution (LR) cosmological simulations.

Spectral Templates Optimal for Selecting Galaxies at z > 8 with the JWST

The Astrophysical Journal, 2023
The selection of high-redshift galaxies often involves spectral energy distribution (SED) fitting to photometric data, an expectation for contamination levels, and measurement of sample completeness—all vetted through comparison to spectroscopic redshift

Not So Heavy Metals: Black Hole Feedback Enriches The Circumgalactic Medium [PDF]

, 2018
We examine the effects of SMBH feedback on the CGM using a cosmological hydrodynamic simulation \citep[{\sc Romulus25};][]{Tremmel2017} and a set of four zoom-in `genetically modified' Milky Way-mass galaxies sampling different evolutionary paths.
