Resolved HII Regions with SIGNALS
Nebular emission lines are some of our most powerful tools for studying galaxies. From a handful of bright lines, we routinely estimate properties of star-forming regions (and …
HII Region Filling Factors in NGC 628: Luminosity-Size Relation and Connection with PAH Emission
*Aims.* Understanding the internal structure of H II regions is fundamental to constraining star-formation processes in galaxies. We investigate how the *filling factor* (FF) …

SIGNALS of Giant HII Regions: A Spatially Resolved Analysis of NGC 604
Observing giant H II regions at fine spatial scales uncovers detailed structures and reveals variations in ionization, abundance, and dynamical properties of ionized gas and the …
SIGNALS of Giant HII Regions: A Spatially Resolved Analysis of NGC 604
A 5-minute oral presentation delivered to the American Astronomical Society. This covers a recent completed paper on the spatially resolved data of NGC 604 as part of the SIGNALS …
Poster: SIGNALS of Giant HII Regions: Resolved Ionization & Abundance Properties of NGC 604
A poster presentation about my work investigating the spatially-resolved properties of NGC 604.
Ionized gas in NGC 4258: Exploring the AGN - Star formation connection
NGC 4258 is a prime target for studying feedback in Low-Luminosity Active Galactic Nuclei (LLAGNs) due to its proximity and comprehensive multi-wavelength coverage. Using new …

AggieSTAAR: Introduction to HII Regions
This talk was given as part of a weekly lunch talk for the undergraduates in the Aggie Scholarships for Technology Advancements in Astronomical Research (AggieSTAAR) program. In …
The SIGNALS from HII Regions
An invited review talk at the SIGNALS workshop about HII regions, pockets of gas ionized by hot stars. In this talk, I give an overview of the work that has been done about HII …
Explaining the Abundance-Ionization Correlation in HII Regions with NGC 628
An invited presentation about my work investigating the correlation between the ionization parameter and oxygen abundance in NGC 628.
SIGNALS on the mixing of oxygen and nitrogen in the spiral galaxy NGC 6946
As part of the SIGNALS survey, which comprises a sample of approximately 40 nearby galaxies observed with the Fourier transform spectrometer SITELLE, we present a study of metal …
