We perform a sample of N-body simulations of a minor merger between a Milky Way type galaxy and a satellite, which is density scaled version of the primary...
Galaxy merger challenge: A comparison study between machine learning-based detection methods
Aims: Various galaxy merger detection methods have been applied to diverse datasets. However, it is difficult to understand how they compare. Our aim is to...
Gauss-Seidel and Successive Overrelaxation Methods for Radiative Transfer with Partial Frequency Redistribution
The linearly polarized solar limb spectrum that is produced by scattering processes contains a wealth of information on the physical conditions and magnetic...
Gaussian covariance matrices for anisotropic galaxy clustering measurements
Measurements of the redshift-space galaxy clustering have been a prolific source of cosmological information in recent years. Accurate covariance estimates are...
Gaussianity of the cosmic microwave background: smooth goodness-of-fit tests applied to interferometric data
We adapt the smooth tests of goodness-of-fit developed by Rayner and Best to the study of the non-Gaussianity of interferometric observations of the cosmic...
GLACE survey: Galaxy activity in ZwCl0024+1652 cluster from strong optical emission lines
Although ZwCl0024+1652 galaxy cluster at z ∼ 0.4 has been thoroughly analysed, it lacks a comprehensive study of star formation and nuclear activity of its...
Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS
Aims: DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar...
Gliese 49: activity evolution and detection of a super-Earth. A HADES and CARMENES collaboration
Context. Small planets around low-mass stars often show orbital periods in a range that corresponds to the temperate zones of their host stars which are...
Context. The Hayabusa2 spacecraft launched by Japan Aerospace Exploration Agency has been conducting observations of the asteroid (162173) Ryugu since June 2018...
