SDSS-IV MaNGA: a distinct mass distribution explored in slow-rotating early-type galaxies
(OXFORD UNIV PRESS, 2018)
We study the radial acceleration relation (RAR) for early-type galaxies (ETGs) in the SDSS MaNGA MPL5 data set. The complete ETG sample show a slightly offset RAR from the relation reported by McGaugh et al. (2016) at the ...
Globular cluster systems as tracers of the evolutionary history in NGC 3258 and NGC 3268
(Wiley Blackwell Publishing, Inc, 2017-09)
We present a new photometric study of NGC 3258 and NGC 3268 globular cluster systems (GCSs), using images in filters B, C, V, R, I and z', obtained from four different telescopes. The wide spatial coverage allows us to ...
Assembly of spheroid-dominated galaxies in the EAGLE simulation
(EDP Sciences, 2019-08)
Context. Despite the insights gained in the last few years, our knowledge about the formation and evolution scenario for the spheroid-dominated galaxies is still incomplete. New and more powerful cosmological simulations ...
Stellar kinematics across the Hubble sequence in the CALIFA survey: General properties and aperture corrections
(EDP Sciences, 2017-01)
We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies displaying a wide range of morphologies across the Hubble sequence, ...
Brightest cluster galaxies: The centre can(not?) hold
(Wiley Blackwell Publishing, Inc, 2021-01)
We explore the persistence of the alignment of brightest cluster galaxies (BCGs) with their local environment. We find that a significant fraction of BCGs do not coincide with the centroid of the X-ray gas distribution ...
On the precursors of fossil groups

Spectroscopic aperture biases in inside-out evolving early-type galaxies from CALIFA
(EDP SCIENCES, 2016)
Integral field spectroscopy (IFS) studies based on CALIFA survey data have recently revealed ongoing low-level star formation (SF) in the periphery of a small fraction (similar to 10%) of local early-type galaxies (ETGs), ...
First confirmed ultra-compact dwarf galaxy in the NGC 5044 group
(EDP Sciences, 2017-03)
Context: Ultra-compact dwarfs (UCDs) are stellar systems displaying colours and metallicities between those of globular clusters (GCs) and early-type dwarf galaxies, as well as sizes of Reff ≲ 100 pc and luminosities in ...
Mid-infrared colour gradients and the colour-magnitude relation in virgo early-type galaxies
(Monthly Notices of the Royal Astronomical Society, 2010)
