    Stellar populations in brightest cluster galaxies by Loubser, S, Sanchez-Blazquez, P, Soechting, I, Sansom, A

    Published 2010
    “…We present the results of an investigation of a large sample of brightest cluster galaxies (BCGs), their kinematic and stellar population properties and the relationships between these and the properties of the host clusters. …”

    Stellar populations in the SAMI Galaxy Survey by Watson, PJ

    Published 2023
    “…We apply this method to galaxies drawn from the SAMI Galaxy Survey, deriving seeing-corrected radial stellar population gradients for 1453 galaxies. On average, galaxies in our sample have flat age and [α/Fe] gradients, but negative metallicity gradients. …”

    Stellar populations in KDCs of Sa galaxies by Falcn-Barroso, J, Bacon, R, Cappellari, M, Davies, R, De Zeeuw, P, Emsellem, E, Krajnović, D, Kuntschner, H, McDermid, R, Peletier, R, Sarzi, M, Van De Ven, G

    Published 2006
    “…We show how the V/ maps can be used to highlight the presence of the KDC and investigate their stellar populations (i.e. age) to understand their origin (i.e. secular vs hierarchical scenarios). …”

    Extended Stellar Populations in Ultrafaint Dwarf Galaxies by Elisa A. Tau, A. Katherina Vivas, Clara E. Martínez-Vázquez

    Published 2024-01-01
    “…Adding to our list of 120 RR Lyrae stars the observations of other ultrafaint dwarf galaxies that were beyond the reach of our search, we find that at least 10 of these galaxies have RR Lyrae stars located at distances greater than four times their respective half-light radius, which implies that at least 33% of the 30 ultrafaint dwarfs with a population of RR Lyrae stars have extended stellar populations.…”

    Stellar population in star formation regions of galaxies by Gusev Alexander S., Shimanovskaya Elena V., Shatsky Nikolai I., Sakhibov Firouz, Piskunov Anatoly E., Kharchenko Nina V.

    Published 2018-05-01
    “…We assume that this is due to spatial offset of Hii clouds with respect to the related stellar population.We developed a method to estimate age of stellar population of the studied complexes using their morphology and the relation with associated H emission region. …”

    Stellar populations in the centres of brightest cluster galaxies by Loubser, S, Sanchez-Blazquez, P, Sansom, A, Soechting, I

    Published 2009
    “…This paper is part of a series devoted to the study of the stellar populations in brightest cluster galaxies (BCGs), aimed at setting constraints on the formation and evolution of these objects. …”

    The stellar populations of the M31 halo substructure by Ferguson, AMN, Johnson, R, Faria, D, Irwin, M, Ibata, R, Johnston, K, Lewis, G, Tanvir, N

    Published 2005
    “…We discuss the stellar populations associated with five prominent stellar overdensities discovered during the course of our panoramic ground-based imaging survey with the Isaac Newton Telescope Wide-Field Camera; a sixth pointing targets a region of "clean" halo. …”

    Stellar populations across cD galaxies by Loubser, S, Sansom, A, Soechting, I

    Published 2006
    “…More is being observed with the GEMINI telescopes, to create a statistically significant sample. Unresolved stellar populations will be used to investigate the history of when stars formed in these galaxies. …”

    Neural Stellar Population Synthesis Emulator for the DESI PROVABGS by K. J. Kwon, ChangHoon Hahn, Justin Alsing

    Published 2023-01-01
    “…Each posterior distribution will be inferred from joint Bayesian modeling of observed photometry and spectroscopy using Markov Chain Monte Carlo sampling and the Hahn et al. stellar population synthesis (SPS) model. To make this computationally feasible, PROVABGS will use a neural emulator for the SPS model to accelerate the posterior inference. …”
