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…
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-…
The Burstiness of Star Formation at : A Huge Diversity in the Recent Star Formation Histories of Very UV-faint Galaxies
Ryan Endsley, John Chisholm, Daniel P. Stark +2
IRAC data have long implied that early () galaxies often have very high specific star formation rates (sSFR30 Gyr), but JWST data have shown that at leas…
JWST Observations of Starbursts: Cold Clouds and Plumes Launching in the M82 Outflow
Deanne B. Fisher, Alberto D. Bolatto, John Chisholm +28
In this paper we study the filamentary substructure of 3.3 m PAH emission from JWST/NIRCam observations in the base of the M82 star-burst driven wind. We identify plume-like sub…
DUVET: Resolved direct metallicity measurements in the outflow of starburst galaxy NGC 1569
Magdalena J. Hamel-Bravo, Deanne B. Fisher, Danielle Berg +15
We present the results of direct-method metallicity measurements in the disk and outflow of the low-metallicity starburst galaxy NGC 1569. We use Keck Cosmic Web Imager observation…
[Ne v] emission from a faint epoch of reionization-era galaxy: evidence for a narrow-line intermediate mass black hole
J. Chisholm, D. A. Berg, R. Endsley +16
Here we present high spectral resolution NIRSpec observations of GN42437, a low-mass (log(M), compact (pc), extreme starburst galaxy…
DUVET: sub-kiloparsec resolved star formation driven outflows in a sample of local starbursting disk galaxies
Bronwyn Reichardt Chu, Deanne B. Fisher, John Chisholm +13
We measure resolved (kiloparsec-scale) outflow properties in a sample of 10 starburst galaxies from the DUVET (Deep near-UV observations of Entrained gas in Turbulent galaxies) sam…
SDSS-IV MaNGA: Properties of galaxies with kinematically decoupled stellar and gaseous components
Yifei Jin, Yanmei Chen, Yong Shi +30
We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical…
