Beyond MHD: modeling and observation of partially ionized solar plasma processes
The temperature and density conditions in the magnetized photosphere and chromosphere of the Sun lead to a very small degree of atomic ionization. At particular...
Beyond the Hubble Sequence — Exploring Galaxy Morphology with Unsupervised Machine Learning
Conventionally, galaxy morphological classifications are defined by visual assessment. However, visual classification systems such as Hubble types can be...
We present the analysis of the photometric and spectroscopic properties of a sample of 29 low redshift (z 0.6) QSOs for which both HST WFPC2 optical images and...
Biases in the estimation of velocity dispersions and dynamical masses for galaxy clusters
Using a set of 73 numerically simulated galaxy clusters, we have characterised the statistical and physical biases for three velocity dispersion and mass...
