Autor: Şen, Ş., Peletier, R. F., Boselli, A., Brok, M. den, Falcón-Barroso, J., Hensler, G., Janz, J., Laurikainen, E., Lisker, T., Mentz, J. J., Paudel, S., Salo, H., Sybilska, A., Toloba, E., van de Ven, G., Vazdekis, A., Yesilyaprak, C.

We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magnitude range -19.0 < Mr < -16.0. We analyze their absorption line-stren

Report

Abundance ratios and IMF slope in the dwarf elliptical galaxy NGC~1396 with MUSE

Autor: Mentz, J. J., La Barbera, F, Peletier, R. F., Falcón-Barroso, J., Lisker, T., van de Ven, G., Loubser, S. I., Hilker, M., Sánchez-Janssen, R., Napolitano, N., Cantiello, M., Capaccioli, M., Norris, M., Paolillo, M., Smith, R., Beasley, M. A., Lyubenova, M., Munoz, R., Puzia, T.

Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (M$_V = -16.60$, Mass $\sim 4\times10^8$ M$_\odot$), located in the Fornax cluster, have been performed with the VLT/ MUSE spectrograph in the wavelength region from $4750-9350$ \AA{}. In

Report

A monolithic collapse origin for the thin/thick disc structure of ESO 243-49

Autor: Comerón, S., Salo, H., Peletier, R. F., Mentz, J.

Publikováno v: A&A 593, L6 (2016)

ESO 243-49 is a high-mass (circular velocity $v_{\rm c}\approx200\,{\rm km\,s^{-1}}$) edge-on S0 galaxy in the Abell 2877 cluster at a distance of $\sim95\,{\rm Mpc}$. To elucidate the origin of its thick disc, we use MUSE science verification data t
