AGN radiation imprints on the circumgalactic medium of massive galaxies
Aura Obreja, Fabrizio Arrigoni Battaia, Andrea V. Macciò +1
Active Galactic Nuclei (AGN) in cosmological simulations generate explosive feedback that regulates star formation in massive galaxies, modifying the gas phase structure out to lar…
Circumgalactic Ly emission around submillimeter-bright galaxies with different quasar contributions
Vale González Lobos, Fabrizio Arrigoni Battaia, Seok-Jun Chang +6
We present VLT/MUSE observations targeting the extended Lyman- (Ly) emission of five high-redshift (3-4) submillimeter galaxies (SMGs) with increasing quasar (QSO) rad…
The impact of early massive mergers on the chemical evolution of Milky Way-like galaxies: insights from NIHAO-UHD simulations
Tobias Buck, Aura Obreja, Bridget Ratcliffe +4
Recent observations of the Milky Way (MW) found an unexpected steepening of the star-forming gas metallicity gradient around the time of the Gaia-Sausage-Enceladus (GSE) merger eve…
Milky Way-like galaxies: stellar population properties of dynamically defined disks, bulges and stellar halos
Sara Ortega-Martinez, Aura Obreja, Rosa Dominguez-Tenreiro +3
The formation of galaxies can be understood in terms of the assembly patterns of each type of galactic component. To perform this kind of analysis, is necessary to define some crit…
NIHAO XI: Formation of Ultra-Diffuse Galaxies by outflows
Arianna Di Cintio, Chris B. Brook, Aaron A. Dutton +3
We address the origin of Ultra-Diffuse Galaxies (UDGs), which have stellar masses typical of dwarf galaxies but effective radii of Milky Way-sized objects. Their formation mechanis…
NIHAO X: Reconciling the local galaxy velocity function with Cold Dark Matter via mock HI observations
Andrea V. Macciò, Silviu M. Udrescu, Aaron A. Dutton +4
We used 87 high resolution hydrodynamical cosmological simulations from the NIHAO suite to investigate the relation between the maximum circular velocity (Vmax) of a dark matter ha…
