ReSolve CoE (Astroinformatics research group) determined magnetic helicity spectrum

Evidence of turbulent dynamo action in the Sun

Astroinformatics research group has determined magnetic helicity spectrum from the solar surface observations using the recently developed two-scale formalism.

Figure 1. Butterfly diagram of f-mode energy variations, computed from collapsed ring diagrams. The temporal average has been subtracted from the data, and is shown as the black line in the right panel. Its error bars represent the time-averaged standard deviation of the fluctuations of the f-mode energy around the signal for every bin.

Surface gravity oscillation mode shows remarkable solar cycle dependence

12 years of satellite data was used to reveal an enigmatic behaviour of the surface-gravity wave energy contained in the most quiet regions on solar surface.

Dust destruction in Supernova blast waves

A supernova explosion blasts hot supersonic plasma, destroying more interstellar dust in its path than fits current theory or observations of dust abundances in early galaxies.

Public transport networks

In our research project we aim to collect public transport timetable data around the world, curate the data, and publish it in a variety of formats available to be used for both transit planners as well as network scientists.

Community detection in complex networks

Most networks are not homogenious, meaning that some sets of nodes are more connected among themselves than to the rest of the network. The aim of community detection is to study this mezo-scale structure and devise algorithms that would identify these sets of nodes.
