SDSS-IV MaStar: Theoretical atmospheric parameters for the MaNGA stellar library (2021)
Journal Article
Hill, L., Thomas, D., Maraston, C., Yan, R., Neumann, J., Lundgren, A., …Beers, T. C. (2022). SDSS-IV MaStar: Theoretical atmospheric parameters for the MaNGA stellar library. Monthly Notices of the Royal Astronomical Society, 509(3), 4308-4329. https://doi.org/10.1093/mnras/stab3263

We calculate the fundamental stellar parameters effective temperature, surface gravity, and iron abundance - Teff, log g, [Fe/H] - for the final release of the Mapping Nearby Galaxies at APO (MaNGA) Stellar Library (MaStar), containing 59 266 per-vis...

Galaxy Zoo: 3D - Crowdsourced bar, spiral, and foreground star masks for MaNGA target galaxies (2021)
Journal Article
Masters, K. L., Krawczyk, C., Shamsi, S., Todd, A., Finnegan, D., Bershady, M., …Yan, R. (2021). Galaxy Zoo: 3D - Crowdsourced bar, spiral, and foreground star masks for MaNGA target galaxies. Monthly Notices of the Royal Astronomical Society, 507(3), 3923-3935. https://doi.org/10.1093/mnras/stab2282

The challenge of consistent identification of internal structure in galaxies - in particular disc galaxy components like spiral arms, bars, and bulges - has hindered our ability to study the physical impact of such structure across large samples. In... Read More about Galaxy Zoo: 3D - Crowdsourced bar, spiral, and foreground star masks for MaNGA target galaxies.

Clusters' far-reaching influence on narrow-angle tail radio galaxies (2021)
Journal Article
de Vos, K., Hatch, N. A., Merrifield, M. R., & Mingo, B. (2021). Clusters' far-reaching influence on narrow-angle tail radio galaxies. Monthly Notices of the Royal Astronomical Society: Letters, 506(1), L55-L58. https://doi.org/10.1093/mnrasl/slab075

In order to study the ram-pressure interaction between radio galaxies and the intracluster medium, we analyse a sample of 208 highly bent narrow-angle tail radio sources (NATs) in clusters, detected by the Low-Frequency Array Two-metre Sky Survey. Fo... Read More about Clusters' far-reaching influence on narrow-angle tail radio galaxies.

An analytical model to kinematically identify thin discs in MaNGA galaxies (2021)
Journal Article
Bershady, M. A., Weijmans, A., Yang, M., Boardman, N. F., Merrifield, M., & Drory, N. (2021). An analytical model to kinematically identify thin discs in MaNGA galaxies. Monthly Notices of the Royal Astronomical Society, 504(2), 2658-2669. https://doi.org/10.1093/mnras/stab1049

We present an analytical model to identify thin discs in galaxies, and apply this model to a sample of SDSS MaNGA galaxies. This model fits the velocity and velocity dispersion fields of galaxies with regular kinematics. By introducing two parameters...

Infrared lags in the light curves of AGN measured using a deep survey (2021)
Journal Article
Elmer, E., Merrifield, M., Almaini, O., Hartley, W. G., & Maltby, D. T. (2021). Infrared lags in the light curves of AGN measured using a deep survey. Monthly Notices of the Royal Astronomical Society: Letters, 503(1), L47-L50. https://doi.org/10.1093/mnrasl/slab023

Information on the structure around active galactic nuclei (AGNs) has long been derived from measuring lags in their varying light output at different wavelengths. In principle, infrared data would reach to larger radii, potentially even probing repr... Read More about Infrared lags in the light curves of AGN measured using a deep survey.

SDSS-IV MaNGA: the “G-dwarf problem” revisited (2021)
Journal Article
Greener, M. J., Merrifield, M., Aragón-Salamanca, A., Peterken, T., Andrews, B., & Lane, R. R. (2021). SDSS-IV MaNGA: the “G-dwarf problem” revisited. Monthly Notices of the Royal Astronomical Society: Letters, 502(1), L95–L98. https://doi.org/10.1093/mnrasl/slab012

The levels of heavy elements in stars are the product of enhancement by previous stellar generations, and the distribution of this metallicity among the population contains clues to the process by which a galaxy formed. Most famously, the “G-dwarf pr... Read More about SDSS-IV MaNGA: the “G-dwarf problem” revisited.
