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 astronomical adaptive optics - I. The software package CAOS
The software package CAOS (code for adaptive optics systems) described in this paper is a software ensemble of modules designed for end-to-end simulation of...
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 Lick spectroscopic indexes with the tunable filters of OSIRIS on GTC
We present the modelling of new indicators for old and intermediate age stellar populations based on the absorption features of Mg λ ˜ 5175 Å, Fe λ ˜ 4383 Å...
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...
Stellar flare research is an exciting and rapidly developing field of astrophysics. The Sun is an invaluable proving ground to test predictions of flare...
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 star counts in the Monoceros stream and the Galactic anti-centre
Context. There is a continuing debate as to the form of the outer disc of the Milky Way galaxy, which has important implications for understanding the Galaxy's...
