Correction to Conversions between gas-phase metallicities in MaNGA

Jillian M. Scudder, Sara L. Ellison, Loubna El Meddah El Idrissi +1

We present a brief correction to Scudder et al. (2021) due to an error in the O3N2 based metallicity calibrations presented in that work. Conclusions are unchanged, but metallicity…

The ALMaQUEST Survey X: What powers merger induced star formation?

Mallory D. Thorp, Sara L. Ellison, Hsi-An Pan +5

Galaxy mergers are known to trigger both extended and central star formation. However, what remains to be understood is whether this triggered star formation is facilitated by enha…

Conversions between gas-phase metallicities in MaNGA

Jillian M. Scudder, Sara L. Ellison, Loubna El Meddah El Idrissi +1

We present polynomial conversions between each of 11 different strong line gas-phase metallicity calibrations, each based on 1.1 million star-forming spaxels in the public S…

A re-assessment of strong line metallicity conversions in the machine learning era

Hossen Teimoorinia, Mansoureh Jalilkhany, Jillian M. Scudder +2

Strong line metallicity calibrations are widely used to determine the gas phase metallicities of individual HII regions and entire galaxies. Over a decade ago, based on the Sloan D…

The ALMaQUEST Survey: V. The non-universality of kpc-scale star formation relations and the factors that drive them

Sara L. Ellison, Lihwai Lin, Mallory D. Thorp +5

Using a sample of ~15,000 kpc-scale star-forming spaxels in 28 galaxies drawn from the ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) survey, we investigate the galaxy-to-gala…

The ALMaQUEST Survey: II. What drives central starbursts at z~0?

Sara L. Ellison, Mallory D. Thorp, Hsi-An Pan +5

Starburst galaxies have elevated star formation rates (SFRs) for their stellar mass. In Ellison et al. (2018) we used integral field unit (IFU) maps of star formation rate surface…
