DOI: 10.1051/0004-6361/201630218
Abstract: We present new evidence for eight early-type galaxies (ETGs) from the CALIFA Survey that show clear rotation around their major photometric axis (“prolate rotation”). These are LSBCF560-04, NGC 0647, NGC 0810, NGC 2484, NGC 4874,… read more here.

DOI: 10.1051/0004-6361/201935090
Abstract: Observations of neutral hydrogen (HI) and molecular gas show that 50% of all nearby early-type galaxies (ETGs) contain some cold gas. Molecular gas is always found in small gas discs in the central region of… read more here.

DOI: 10.1051/0004-6361/202039408
Abstract: The transformation of late-type galaxies has been suggested as the origin of early-type dwarf galaxies in galaxy clusters. Venhola et al. analysed correlations between colour and surface brightness for galaxies in the Fornax cluster binned… read more here.

DOI: 10.1093/mnras/staa3996
Abstract: We present a set of self-consistent chemo-dynamical simulations of MW-type galaxies formation to study the origin of the bimodality of $\alpha$-elements in stellar populations. We explore how the bimodality is related to the geometrically and… read more here.

DOI: 10.1093/mnras/stab1996
Abstract: The change of the total mass density slope, γ, of early-type galaxies through cosmic time is a probe of evolutionary pathways. Hydrodynamical cosmological simulations show that at high redshifts density profiles of early-type galaxies were… read more here.

DOI: 10.1093/mnras/sty528
Abstract: In this paper, we investigate whether the stellar initial mass function (IMF) of early-type galaxies depends on their host environment. To this purpose, we have selected a sample of early-type galaxies from the SPIDER catalogue,… read more here.

DOI: 10.1093/mnras/sty740
Abstract: A tight far-infrared - radio correlation similar to that in star-forming late-type galaxies is also indicated in star-forming blue early-type galaxies, in which the nuclear optical-line emissions are primarily due to star-forming activities without a… read more here.
