Vigorous star formation in a bulge-dominated extremely red object at z=1.34 by Cotter, G, Simpson, C, Bolton, R

“…Even though our first target has many of the properties of an old elliptical, the ongoing star formation means that it cannot have formed all of its stellar population at high redshift. While we cannot infer any robust values for the SFR in ellipticals at z > 1 from this one object, we argue that the presence of an object with such a high SFR in such a small sample suggests that a non-negligible fraction of the elliptical galaxy population may have formed a component of their stellar population at redshifts z ∼ 1-2. …”

Galaxy and mass assembly (GAMA): the consistency of GAMA and WISE derived mass-to-light ratios by Kettlety, T, Hesling, J, Phillipps, S, Bremer, MN, Cluver, ME, Taylor, EN, Bland-Hawthorn, J, Brough, S, De Propris, R, Driver, SP, Holwerda, BW, Kelvin, LS, Sutherland, W, Wright, AH

“…Recent work has suggested that mid-IR wavelengths are optimal for estimating the mass-tolight ratios of stellar populations and hence the stellar masses of galaxies. …”

EVIDENCE FOR DARK MATTER CONTRACTION AND A SALPETER INITIAL MASS FUNCTION IN A MASSIVE EARLY-TYPE GALAXY by Sonnenfeld, A, Treu, T, Gavazzi, R, Marshall, P, Auger, M, Suyu, S, Koopmans, L, Bolton, A

“…Stars and dark matter account for most of the mass of early-type galaxies, but uncertainties in the stellar population and the dark matter profile make it challenging to distinguish between the two components. …”

Mass–Metallicity Relationship of SDSS Star-forming Galaxies: Population Synthesis Analysis and Effects of Star Burst Length, Extinction Law, Initial Mass Function, and Star Formati... by Eva Sextl, Rolf-Peter Kudritzki, H. Jabran Zahid, I-Ting Ho

The planetary nebulae population in the nuclear regions of M31: the SAURON view by Pastorello, N, Sarzi, M, Cappellari, M, Emsellem, E, Mamon, G, Bacon, R, Davies, R, de Zeeuw, P

“…The study of extragalactic planetary nebulae (PNe) in the optical regions of galaxies, where the properties of their stellar population can be best characterized, is a promising ground to better understand the late evolution of stars across different galactic environments. …”

Kinematic constraints on the stellar and dark matter content of spiral and S0 galaxies by Williams, M, Bureau, M, Cappellari, M
