The VIRUS-dE Survey I: Stars in dwarf elliptical galaxies - 3D dynamics and radially resolved stellar initial mass functions
Mathias Lipka, Jens Thomas, Roberto Saglia +9
We analyse the stellar structure of a sample of dwarf ellipticals (dE) inhabiting various environments within the Virgo cluster. Integral-field observations with a high spectral re…
Stellar populations of massive early-type galaxies observed by MUSE
Taniya Parikh, Roberto Saglia, Jens Thomas +3
Stellar population studies of massive early-type galaxies (ETGs) suggest that the stellar initial mass function may not be universal. In particular, the centres of ETGs seem to con…
Dynamical stellar mass-to-light ratio gradients: Evidence for very centrally concentrated IMF variations in ETGs?
Kianusch Mehrgan, Jens Thomas, Roberto Saglia +4
Evidence from different probes of the stellar initial mass function (IMF) of massive early-type galaxies (ETGs) has repeatedly converged on IMFs more bottom-heavy than in the Milky…
Composite Bulges -- III. A Study of Nuclear Star Clusters in Nearby Spiral Galaxies
Aishwarya Ashok, Anil Seth, Peter Erwin +17
We present photometric and morphological analyses of nuclear star clusters (NSCs) -- very dense, massive star clusters present in the central regions of most galaxies -- in a sampl…
Detailed shapes of the line-of-sight velocity distributions in massive early-type galaxies from non-parametric spectral models
Kianusch Mehrgan, Jens Thomas, Roberto Saglia +2
We present the first systematic study of the detailed shapes of the line-of-sight velocity distributions (LOSVDs) in nine massive early-type galaxies (ETGs) using the novel non-par…
SDSS-IV MaNGA: Radial Gradients in Stellar Population Properties of Early-Type and Late-Type Galaxies
Taniya Parikh, Daniel Thomas, Claudia Maraston +5
We derive ages, metallicities, and individual element abundances of early- and late-type galaxies (ETGs and LTGs) out to 1.5 R. We study a large sample of 1900 galaxies spannin…
