The Simulated Oxygen Shortage (SOS): Mapping the Missing OVI in Simulated Dwarf Galaxies to Subgrid Physics
Daniel R. Piacitelli, Alyson M. Brooks, N. Nicole Sanchez +9
Observations reveal extended \OVI\, reservoirs in the circumgalactic medium (CGM) of dwarf galaxies, yet current simulations systematically underpredict \OVI\, column densities. Ut…
Chemical enrichment of metal-poor stars orbiting massive black hole companions
Alejandra Rosselli-Calderon, Julia Stewart, Sijing Shen +3
There are millions of undetected black holes wandering through our galaxy. Observatories like {\it Chandra}, LIGO, and more recently, {\it Gaia}, have provided valuable insights in…
A theoretical investigation of far-infrared fine structure lines at and of the origin of the [OIII]88/[CII]158 enhancement
Camilla T. Nyhagen, Alice Schimek, Claudia Cicone +2
[Abridged] The [OIII]/[CII] and [OIII]/[NII] luminosity ratios have shown to be promising tracers of the ionisation state and gas-phase me…
The Seven Dwarfs illuminated. The impact of radiation on dwarf galaxies and their circumgalactic medium
Bernhard Baumschlager, Sijing Shen, James W. Wadsley +6
We present a high-resolution cosmological zoom-in simulation of a group of field dwarf galaxies which includes on-the-fly radiative transfer (RT) and is evolved to . Emission…
