Stellar populations in the nuclear regions of nearby radio galaxies by Aretxaga, I, Terlevich, E, Terlevich, R, Cotter, G, Diaz, A

“…The strengths of the absorptions are similar to those found in normal elliptical galaxies, but these values are consistent both with stellar populations of roughly similar ages (as derived from the Balmer absorption and break strengths) and with mixed young+old populations.…”

Variation of stellar populations and dark matter with time and environment by Shetty, S

“…Furthermore, I model the stellar population of the galaxies using a full-spectrum technique while reproducing their star formation history in a non-parametric manner. …”

Probing the stellar populations of early-type galaxies: the SAURON survey by Emsellem, E, Davies, R, McDermid, R, Kuntschner, H, Peletier, R, Bacon, R, Bureau, M, Cappellari, M, Copin, Y, Miller, B, Verolme, E, de Zeeuw, T

Resolving the stellar populations in A z = 4 lensed galaxy by Bunker, A, Moustakas, L, Davis, M

Stellar populations of kinematically decoupled cores in E/S0 galaxies by McDermid, R, Emsellem, E, Shapiro, K, Bacon, R, Bureau, M, Cappellari, M, Davies, R, De Zeeuw, T, Falcón-Barroso, J, Krajnovíc, D, Kuntschner, H, Peletier, R, Sarzi, M

“…We derive the stellar and gas kinematics, stellar absorption-line strengths and nebular emission-line strengths for our sample, and derive maps of the luminosity-weighted stellar age, metallicity and abundance ratio via stellar population models. From these data we find a wealth of structures either not seen or poorly resolved in the SAURON data, including a number of kinematically-decoupled cores (KDCs) in the centres of some galaxies. …”

Resolving the stellar populations in a z=4 lensed galaxy by Bunker, A, Moustakas, L, Davis, M

“…In combination with high-quality archival Hubble Space Telescope (HST) WFPC2 data, we can spatially resolve stellar populations along the arcs. The WFPC2 images clearly reveal several bright knots, which correspond to sites of active star formation. …”

The stellar population and initial mass function of NGC 1399 with MUSE by Vaughan, S, Davies, R, Zieleniewski, S, Houghton, R

“…Using data from the Multi Unit Spectroscopic Explorer (MUSE) and updated state-of-the-art stellar population synthesis models from Conroy et al., we use full spectral fitting to measure the low-mass IMF, as well as a number of individual elemental abundances, as a function of radius in this object. …”

Impact of Galaxy Mergers on Stellar Population Profiles of Early-type Galaxies by Yongmin Yoon, Jongwan Ko, Jae-Woo Kim

“…We study the impact of galaxy mergers on stellar population profiles/gradients of early-type galaxies (ETGs) using ETGs at z < 0.055 in the Stripe 82 region of the Sloan Digital Sky Survey and MaNGA integral field unit spectroscopic data. …”

Hierarchical Bayesian Inference of Photometric Redshifts with Stellar Population Synthesis Models by Boris Leistedt, Justin Alsing, Hiranya Peiris, Daniel Mortlock, Joel Leja

“…We present a Bayesian hierarchical framework to analyze photometric galaxy survey data with stellar population synthesis (SPS) models. Our method couples robust modeling of spectral energy distributions with a population model and a noise model to characterize the statistical properties of the galaxy populations and real observations, respectively. …”

Central stellar populations of early-type galaxies in low-density environments by Collobert, M, Sarzi, M, Davies, R, Kuntschner, H, Colless, M

“…We present spectroscopic observations of 22 galaxies from the combined sample, from which central velocity dispersions and the Lick stellar population indices were measured. After carefully correcting the spectra for nebular emission, we derived luminosity-weighted ages, metallicities and α-element abundance ratios. …”

Inflow, outflow, yields, and stellar population mixing in chemical evolution models by Andrews, B, Weinberg, D, Schönrich, R, Johnson, J

“…However, their predictions depend heavily on the treatment of inflow, outflow, star formation efficiency (SFE), the stellar initial mass function, the SN Ia delay time distribution, stellar yields, and stellar population mixing. Using flexCE, a flexible one-zone chemical evolution code, we investigate the effects of and trade-offs between parameters. …”

Internal kinematics and stellar populations of early-type galaxies in the Fornax cluster by Gerken, B, Davies, R, Kuntschner, H

“…We present a study of the internal kinematics and stellar populations of early-type galaxies in the Fornax cluster. 10 galaxies in a luminosity range of 21.8MB17.4 were observed with the integral field units (IFU) of Gemini South GMOS and VLT-VIMOS. …”
