Journal Article
Price-Whelan, A., Sipőcz, B., Günther, H., Lim, P., Crawford, S., Conseil, S., …Bamford, S. (2018). The Astropy Project: building an open-science project and status of the v2.0 core package. Astronomical Journal, 156(3), Article 123. https://doi.org/10.3847/1538-3881/aabc4f

The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of the The Astropy Project supports and fosters the d... Read More about The Astropy Project: building an open-science project and status of the v2.0 core package.

Galaxy Cluster Mass Reconstruction Project – IV. Understanding the effects of imperfect membership on cluster mass estimation (2018)
Journal Article
Wojtak, R., Old, L., Mamon, G., Pearce, F., de Carvalho, R., Sifón, C., …Tempel, E. (2018). Galaxy Cluster Mass Reconstruction Project – IV. Understanding the effects of imperfect membership on cluster mass estimation. Monthly Notices of the Royal Astronomical Society, 481(1), 324-340. https://doi.org/10.1093/mnras/sty2257

The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the line of sight. We study the impact of membership contamination and incomp... Read More about Galaxy Cluster Mass Reconstruction Project – IV.

OMEGA-OSIRIS mapping of emission-line galaxies in A901/2:IV: extinction of star-formation estimators with inclination (2018)
Journal Article
Wolf, C., Weinzirl, T., Aragón-Salamanca, A., Gray, M. E., Rodríguez del Pino, B., Chies-Santos, A. L., …Harborne, K. (2018). OMEGA-OSIRIS mapping of emission-line galaxies in A901/2:IV: extinction of star-formation estimators with inclination. Monthly Notices of the Royal Astronomical Society, 480(3), 3788–3799. https://doi.org/10.1093/mnras/sty2112

We study the effect of inclination on the apparent brightness of star-forming galaxies in spectral passbands that are commonly used as star-formation indicators. As diagnostics we use mass-to-light ratios in three passbands: the UV continuum at 280 n...

Galaxy Zoo: constraining the origin of spiral arms (2018)
Journal Article
Hart, R. E., Bamford, S. P., Keel, W. C., Kruk, S. J., Masters, K. L., Simmons, B. D., & Smethurst, R. J. (2018). Galaxy Zoo: constraining the origin of spiral arms. Monthly Notices of the Royal Astronomical Society, 478(1), 932-949. https://doi.org/10.1093/mnras/sty1201

Since the discovery that the majority of low-redshift galaxies exhibit some level of spiral structure, a number of theories have been proposed as to why these patterns exist. A popular explanation is a process known as swing amplification, yet there... Read More about Galaxy Zoo: constraining the origin of spiral arms.

Galaxy Zoo: Morphological Classification of Galaxy Images from the Illustris Simulation (2018)
Journal Article
Dickinson, H., Fortson, L., Lintott, C., Scarlata, C., Willett, K., Bamford, S., …Snyder, G. F. (2018). Galaxy Zoo: Morphological Classification of Galaxy Images from the Illustris Simulation. Astrophysical Journal, 853(2), Article 194. https://doi.org/10.3847/1538-4357/aaa250

Modern large-scale cosmological simulations model the universe with increasing sophistication and at higher spatial and temporal resolutions. These ongoing enhancements permit increasingly detailed comparisons between the simulation outputs and real...

Galaxy and Mass Assembly (GAMA): morphological transformation of galaxies across the green valley (2018)
Journal Article
Bremer, M., Phillipps, S., Kelvin, L., De Propris, R., Kennedy, R., Moffett, A., …Taylor, E. (in press). Galaxy and Mass Assembly (GAMA): morphological transformation of galaxies across the green valley. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/sty124

We explore constraints on the joint photometric and morphological evolution of typical low redshift galaxies as they move from the blue cloud through the green valley and onto the red sequence. We select GAMA survey galaxies with 10.25 < log(M*/M⊙) <... Read More about Galaxy and Mass Assembly (GAMA): morphological transformation of galaxies across the green valley.
