We investigated the central mass distribution of the luminous infrared galaxy NGC 3256 at a distance of 35 Mpc by using

This paper presents the observed data from the rotation curve of NGC 4651 galaxy from Very Large Array (VLA) and examine the results from isothermal and Bose–Einstein Condensate models. It is found that both models can be closed to the derived rotation curve from observations for this source. By fitting the observed rotation curve with the expectation models, the mass of halo from models is about 2 × 1011 M⊚. Hence, NGC 4651 galaxy can be dominated by the invisible matter.

Investigating the human mobility patterns is a highly interesting field in the 21th century, and it takes vast attention from multi-disciplinary scientists in physics, economic, social, computer, engineering…etc. depending on the concept that relates between human mobility patterns and their communications. Hence, the necessity for a rich repository of data has emerged. Therefore, the most powerful solution is the usage of GSM network data, which gives millions of Call Details Records gained from urban regions. However, the available data still have shortcomings, because it gives only the indication of spatio-temporal data at only the moment of mobile communication activities. In this chapter, Gama platform development environment of constructing spatially multi agent simulation is used for modeling and simulating the individual reconstructed trajectories. As a result, the individual trajectories revealed the human daily life patterns.
