The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Speed Distributions

Ethan Lilie, Jonah C. Rose, Mariangela Lisanti +14

Direct detection experiments require information about the local dark matter speed distribution to produce constraints on dark matter candidates, or infer their properties in the e…

The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles

Alex M. Garcia, Jonah C. Rose, Paul Torrey +23

In this work, we utilize a new suite of Milky Way-mass halos from the DREAMS Project, simulated with Cold Dark Matter (CDM), to quantify the influence of baryon feedback and intrin…

The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Satellite Galaxies

Jonah C. Rose, Mariangela Lisanti, Paul Torrey +24

We analyze the properties of satellite galaxies around 1,024 Milky Way-mass hosts from the DREAMS Project, simulated within a CDM cosmology. Utilizing the TNG galaxy-formation m…

The DREAMS Project: A New Suite of 1,024 Simulations to Contextualize the Milky Way and Assess Physics Uncertainties

Jonah C. Rose, Mariangela Lisanti, Paul Torrey +17

We introduce a new suite of 1,024 cosmological and hydrodynamical zoom-in simulations of Milky Way-mass halos, run with Cold Dark Matter, as part of the DREAMS Project. Each simula…

Linking Warm Dark Matter to Merger Tree Histories via Deep Learning Networks

Ilem Leisher, Paul Torrey, Alex M. Garcia +11

Dark matter (DM) halos form hierarchically in the Universe through a series of merger events. Cosmological simulations can represent this series of mergers as a graph-like ``tree''…

Finding the boundary: Using galaxy membership to inform galaxy cluster extent through machine learning

Christine Hao, Stephanie O'Neil, Mark Vogelsberger +3

The spatial extent of the environment's impact on galaxies marks a transitional region between cluster and field galaxies. We present a data-driven method to identify this region i…

Self-interacting dark matter in the center of a Local Group dwarf galaxy and its satellites

Thales A. Gutcke, Giulia Despali, Stephanie O'Neil +3

We present a detailed comparison of a Local Group dwarf galaxy analogue evolved in two cosmological models: the standard CDM and a self-interacting dark matter (SIDM) model with…

Measuring the splashback feature: Dependence on halo properties and history

Qiaorong S. Yu, Stephanie O'Neil, Xuejian Shen +7

In this study, we define the novel splashback depth and width to examine how the splashback features of dark matter haloes are affected by the physical…

Supersizing hydrodynamical simulations of reionization using perturbative techniques

Wenzer Qin, Katelin Schutz, Olivia Rosenstein +2

We show that perturbative techniques inspired by effective field theory (EFT) can be used to "paint on" the 21~cm field during reionization using only the underlying linear density…

Core collapse in resonant self-interacting dark matter across two decades in halo mass

Vinh Tran, Xuejian Shen, Daniel Gilman +5

Core collapse, a process associated with self-interacting dark matter (SIDM) models, can increase the central density of halos by orders of magnitude with observable consequences f…

Structure Formation under Inelastic Two-Component Dark Matter: Halo Statistics and Matter Power Spectra in the High- Universe

Ryan Low, Rakshak Adhikari, Jonah C. Rose +4

We present hydrodynamic simulations of a flavour-mixed two-component dark matter (2cDM) model that utilize IllustrisTNG baryonic physics. The model parameters are explored for two…

The effects of projection on measuring the splashback feature

Xiaoqing Sun, Stephanie O'Neil, Xuejian Shen +1

The splashback radius is a boundary of a halo that separates infalling and accreted matter. This results in a steep drop in the density profile at , which…
