Theoretical strong line metallicity diagnostics for the JWST era
Prerak Garg, Desika Narayanan, Ryan L. Sanders +5
The ratios of strong rest-frame optical emission lines are the dominant indicator of metallicities in high-redshift galaxies. Since typical strong-line based metallicity indicators…
The BPT Diagram in Cosmological Galaxy Formation Simulations: Understanding the Physics Driving Offsets at High-Redshift
Prerak Garg, Desika Narayanan, Nell Byler +9
The Baldwin, Philips, & Terlevich diagram of [O III]/H vs. [N II]/H (hereafter N2-BPT) has long been used as a tool for classifying galaxies based on the dominant source of i…
Powderday: Dust Radiative Transfer for Galaxy Simulations
Desika Narayanan, Matthew J. Turk, Thomas Robitaille +18
We present Powderday, a flexible, fast, open-source dust radiative transfer package designed to interface with galaxy formation simulations. Powderday builds on FSPS population syn…
A Hard X-ray Test of HCN Enhancements as a Tracer of Embedded Black Hole Growth
G. C. Privon, C. Ricci, S. Aalto +18
Enhanced emission from the dense gas tracer HCN (relative to HCO) has been proposed as a signature of active galactic nuclei (AGN). In a previous single-dish millimeter line s…
Origin of low surface brightness galaxies: A dynamical study
Prerak Garg, Arunima Banerjee
Low Surface Brighness Galaxies (LSBs), inspite of being gas rich, have low star formation rates and are, therefore, low surface brightness in nature. We calculate Q, th…
