The Prevalence of Turbulence-Regulated Multiphase Galactic Winds in Star-Forming Galaxies

Zhihui Li, Timothy Heckman, Max Gronke +8

We build upon our previously developed multi-ion radiative transfer (RT) framework, PEACOCK, to investigate the kinematic and energetic structure of cool-to-warm galactic winds in…

Kinematically Coherent Multiphase Galactic Winds in Star-Forming Galaxies Revealed by Unified Radiative Transfer Modeling of UV Emission and Absorption Lines

Zhihui Li, Timothy Heckman, Max Gronke +8

We present PEACOCK, a three-dimensional Monte Carlo radiative transfer (RT) framework designed to self-consistently model rest-frame ultraviolet emission and absorption lines arisi…

Feedback and dynamical masses in high- galaxies: the advent of high-resolution NIRSpec spectroscopy

A. Saldana-Lopez, J. Chisholm, S. Gazagnes +11

Stellar feedback is an essential step in the baryon cycle of galaxies, but it remains unconstrained beyond Cosmic Noon. We study the ionized gas kinematics, dynamical mass and gas-…

Declining metallicity and extended HeII in the outflow of an epoch of reionization analogue galaxy

M. J. Hamel-Bravo, D. B. Fisher, D. A. Berg +5

We present VLT/X-shooter spectroscopy of the extremely metal-poor starburst galaxy SBS 0335-052E, a nearby (D 54 Mpc) analog of high-redshift systems, probing its outflow up…

Electron temperature relations in low metallicity, diffuse, and extraplanar gas of starburst galaxies

Magdalena J. Hamel-Bravo, Deanne B. Fisher, Danielle A. Berg +6

In this work, we test the validity of - relations in resolved (10-200~pc) measurements of four nearby, low-metallicity (7.25 12+log(O/H) 8.33), low-mass (…

Emission Line Diagnostics for IMBHs in Dwarf Galaxies: Accounting for BH Seeding and ULX Excitation

Chris T. Richardson, Jordan Wels, Kristen Garofali +13

Dwarf AGN serve as the ideal systems for identifying intermediate mass black holes (IMBHs) down to the most elusive regimes (). However, the ubiquitousl…
