Astrophysical evidence indicates that 23% of our universe's energy density is in the form of nonluminous, nonbaryonic matter referred to as dark matter. One theoretically appealing dark matter candidate is the Weakly Interacting Massive Particle (WIMP). Because of astrophysical dynamics, the detectable signal from the expected WIMP dark matter halo should exhibit a unique daily directional modu...
During their exposure, nuclear emulsion sheets detect both tracks from experimentrelated particles, as well as a considerable amount of background tracks, mainly due to cosmic rays. Unless the exposure has been fairly short, it is therefore fairly likely that a fraction of the tracks that have been identified as belonging to the particles the experiment is interested in, are really due to backg...
A computer program named TRIAC II written in MATLAB and running with a friendly GUI has been developed for recognition and parameters measurements of particles’ tracks from images of Solid State Nuclear Track Detectors. The program, using image analysis tools, counts the number of tracks and depending on the current working mode classifies them according to their radii (Mode I—circular tracks) ...
Detailed examination of the balance between star-formation and nuclear activity in AGN and starburst galaxies leads to the composition of an Hertzsprung-Russell diagram in which possible evolutionary tracks can be drawn. It is likely that these tracks also relate to the level of obscuration.
