How the Cookie Crumbles: A Model for Star-forming Clumps in High-redshift Disk Galaxies
Matthew E. Orr, Douglas Rennehan
We present a simple model for the number distribution of maximally star-forming clumps in rotating disk galaxies, at high- with high gas surface densities. By combining assumpti…
Diverse dark matter profiles in FIRE dwarfs: black holes, cosmic rays and the cusp-core enigma
Sophie Koudmani, Douglas Rennehan, Rachel S. Somerville +5
Dwarf galaxies have historically posed challenges to the cold dark matter (CDM) model and, while many of the so-called 'dwarf galaxy problems' have been mitigated by incorporating…
COSMOS Brightest Group Galaxies -- III: Evolution of stellar ages
G. Gozaliasl, A. Finoguenov, A. Babul +15
The unique characteristics of the brightest group galaxies (BGGs) link the evolutionary continuum between galaxies like the Milky Way and more massive BCGs in dense clusters. This…
Modelling the multi-wavelength detection of protoclusters. I: An excess of submillimetre galaxies in protocluster cores
Pablo Araya-Araya, Rachel K. Cochrane, Christopher C. Hayward +6
Studies of galaxy protoclusters yield insights into galaxy cluster formation complementary to those obtained via `archaeological' studies of present-day galaxy clusters. Submillime…
Pumping Iron: How turbulent metal diffusion impacts multiphase galactic outflows
Ulrich P. Steinwandel, Douglas Rennehan, Matthew E. Orr +2
Most numerical simulations of galaxy formation and evolution are unable to properly resolve the turbulent cascade at or below the resolution scale and turbulence models are require…
A massive, neutral gas reservoir permeating a galaxy proto-cluster after the reionization era
Kasper E. Heintz, Jake S. Bennett, Pascal A. Oesch +21
Galaxy clusters are the most massive, gravitationally-bound structures in the Universe, emerging through hierarchical structure formation of large-scale dark matter and baryon over…
Hyenas: X-ray Bubbles and Cavities in the Intra-Group Medium
Fred J. Jennings, Arif Babul, Romeel Dave +2
We investigate the role of the Simba feedback model on the structure of the Intra-Group Medium (IGrM) in the new Hyenas suite of cutting-edge cosmological zoom-in simulations. Usin…
A 100 Mpc structure traced by hyperluminous galaxies around a massive = 2.85 protocluster
George C. P. Wang, Scott C. Chapman, Nikolaus Sulzenauer +9
We present wide-field mapping at 850 m and 450 m of the = 2.85 protocluster in the HS154919 field using the Submillimetre Common User Bolometer Array 2 (SCUBA-2). Spec…
\texttt{Simba}-\texttt{C}: the evolution of the thermal and chemical properties in the intragroup medium
Renier T. Hough, Zhiwei Shao, Weiguang Cui +5
The newly updated \texttt{GIZMO} and \texttt{Simba} based simulation, \texttt{Simba-C}, with its new stellar feedback, chemical enrichment, and recalibrated AGN feedback, allows fo…
The Manhattan Suite: Accelerated galaxy evolution in the early Universe
Douglas Rennehan
Observational advances have allowed the detection of galaxies, protoclusters, and galaxy clusters at higher and higher redshifts, opening a new view into extreme galaxy evolution.…
Identifying Galaxy Cluster Mergers with Deep Neural Networks using Idealized Compton-y and X-ray maps
Ashleigh R. Arendt, Yvette C. Perrott, Ana Contreras-Santos +3
We present a novel approach to identify galaxy clusters that are undergoing a merger using a deep learning approach. This paper uses massive galaxy clusters spanning $0 \leq z \leq…
The Nature and Evolution of Early Massive Quenched Galaxies in the Simba-C Simulation
Jakub Szpila, Romeel Davé, Douglas Rennehan +2
We examine the nature, origin, and fate of early () massive () quenched galaxies (EQGs) in a new run of the Simba-C galaxy…
