Modeling the ionizing spectra of H II regions: individual stars versus stellar ensembles
Aims: We study how IMF sampling affects the ionizing flux and emission line spectra of low mass stellar clusters. Methods: We performed 2 × 106 Monte Carlo...
Modeling the Stellar Populations in the Canis Major Overdensity: The Relation between the Old and Young Populations
We analyze the stellar populations of the Canis Major stellar overdensity using quantitative color-magnitude diagram (CMD) fitting techniques. The analysis is...
Modeling Tidal Streams in Evolving Dark Matter Halos
We explore whether stellar tidal streams can provide information on the secular, cosmological evolution of the Milky Way's gravitational potential and on the...
Modelling gaseous and stellar kinematics in the disc galaxies NGC 772, 3898 and 7782
We present V-band surface photometry and major-axis kinematics of stars and ionized gas of three early-type spiral galaxies, namely NGC 772, 3898 and 7782. For...
Modelling neutral hydrogen in galaxies using cosmological hydrodynamical simulations
The characterization of the atomic and molecular hydrogen content of high-redshift galaxies is a major observational challenge that will be addressed over the...
Modelling of surface brightness fluctuation measurements. Methodology, uncertainty, and recommendations
Aims: The goal of this work is to scrutinise the surface brightness fluctuation (SBF) calculation methodology. We analysed the SBF derivation procedure...
Modelling simple stellar populations in the near-ultraviolet to near-infrared with the X-shooter Spectral Library (XSL)
We present simple stellar population models based on the empirical X-shooter Spectral Library (XSL) from near-ultraviolet (NUV) to near-infrared (NIR)...
Modelling the emission of passive galaxy candidates at z∼3
Early-type galaxies (ETGs) are of crucial importance to trace back the galaxy mass assembly across cosmic time, yet their formation and quenching remain...
