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…
A Spectroscopic Survey of Metal-Poor OB Stars in Local Dwarf Galaxy NGC 3109
Abby Mintz, O. Grace Telford, Evan N. Kirby +3
As JWST uncovers increasingly strong evidence that metal-poor, massive stars in early galaxies dominated reionization, observational constraints on the properties of such stars are…
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-…
