Kinetys II: Constraints on spatial variations of the stellar initial mass function from K-band spectroscopy
P. D. Alton, R. J. Smith, J. R. Lucey
We investigate the spatially resolved stellar populations of a sample of seven nearby massive Early-type galaxies (ETGs), using optical and near infrared data, including K-band spe…
KINETyS: Constraining spatial variations of the stellar initial mass function in early-type galaxies
Padraig D. Alton, Russell J. Smith, John R. Lucey
The heavyweight stellar initial mass function (IMF) observed in the cores of massive early-type galaxies (ETGs) has been linked to formation of their cores in an initial swiftly-qu…
The IMF-sensitive 1.14-micron Na I doublet in early-type galaxies
Russell J. Smith, Padraig Alton, John R. Lucey +2
We present J-band spectroscopy of passive galaxies focusing on the Na I doublet at 1.14 μm. Like the Na I 0.82 μm doublet, this feature is strong in low-mass stars and hence may pr…
