The population of galaxies that contribute to the HI mass function

We look at the contribution of different galaxy populations to the atomic hydrogen (H I) mass function (HIMF) and the H I density parameter, ΩH I, in the local Universe. Our analysis is based on a sample of 7857 H I selected galaxies selected from a …

The EDGE-CALIFA survey: exploring the star formation law using LASSO based variable selection

We present a multilinear analysis to determine the significant predictors of star formation in galaxies using the combined EDGE-CALIFA sample of galaxies. We analyse 1845 kpc-scale lines of sight across 39 galaxies with molecular line emission …

Study of geometric phase using classical coupled oscillators

We illustrate the geometric phase associated with the cyclic dynamics of a classical system of coupled oscillators. We use an analogy between a classical coupled oscillator and a two-state quantum mechanical system to represent the evolution of the …
