The Structure and Star-Formation History of NGC 5461
We compute photoionization models for the giant extragalactic H II region NGC 5461, and compare their predictions to several observational constraints. The...
The structure of Abell 1351: a bimodal galaxy cluster with peculiar diffuse radio emission
We aim to review the internal structure and dynamics of the Abell 1351 cluster, shown to host a radio halo with a quite irregular shape. Our analysis is based...
The structure of Andromeda II dwarf spheroidal galaxy
We analyse in detail the spatial distribution and kinematic properties of two different stellar populations in Andromeda II dwarf spheroidal galaxy. We obtained...
The structure of galactic disks. Studying late-type spiral galaxies using SDSS
Using imaging data from the SDSS survey, we present the g' and r' radial stellar light distribution of a complete sample of ~90 face-on to intermediate inclined...
The structure of the barred galaxy NGC253: target of the VISTA and VST Science Verification extragalactic mini-survey.
The Sculptor Galaxy NGC253 is a nearby barred Sc galaxy seen nearly edge-on and it has been the target of the Science Verification (SV) for the new ESO survey...
The Structure of the Underlying Stellar Host in Blue Compact Dwarf Galaxies
Nowadays it is well established that BCDs are mostly old systems, as the vast majority of them have an extended low-surface brightness (LSB) stellar host...
The Sunyaev-Zeldovich effect in Clusters of Galaxies and the Hubble Constant
The large scale expansion rate of the Universe is given by the value of the Hubble constant. Several methods have been used to determine the Hubble constant...
The survival of stellar discs in Fornax-like environments, from TNG50 to real galaxies
We study the evolution of kinematically defined stellar discs in 10 Fornax-like clusters identified in the TNG50 run from the IllustrisTNG suite of cosmological...
The synchronized dance of the magellanic clouds' star formation history
We use the SMASH survey to obtain unprecedented deep photometry reaching down to the oldest main-sequence turn-offs in the colour-magnitude diagrams (CMDs) of...
