Abstract In this review, we summarize recent advances in the field of dusty plasmas at strong magnetic fields. Special emphasis is put on situations where experimental laboratory observations are available. These generally comprise with magnetized electrons and ions, but unmagnetized dust. The fundamental parameters characterizing a (dusty) plasma given various effects under fields presented. A...

Active galactic nuclei play a key role in the evolution of galaxies, but their inner workings and physical connection to host are poorly understood due lack angular resolution. Infrared interferometry makes it possible resolve circumnuclear dust nearby Seyfert 2 galaxy, Circinus. Previous observations have revealed complex structures polar emission interpretation was limited simple models. MATI...

This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. In the first case, a dusty plasma in thermal equilibrium and with a distribution of grain sizes is considered. A size distributi...

Context. Dusty star-forming galaxies are among the most prodigious systems at high redshift (z > 1), characterized by high starformation rates and huge dust reservoirs. The bright end of this population has been well characterized in recent years, but considerable uncertainties remain for fainter dusty star-forming galaxies, which are responsible for the bulk of star formation at high redshift ...

Since many years we know that dust in the form of dusty-molecular torus is responsible for obscuration active galactic nuclei (AGN) at large viewing angles and thus classification AGN. Recently, gained some observational theoretical insight into geometry region role dynamics outflow failed winds. We will briefly touch on all these aspects, including our dust-based model (FRADO - Failed Radiativ...

Sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. Over thepast decade a large part of Iran has been affected by this phenomenon, and Tehran has not been excluded from thisevent. Therefore, having knowledge of spatiotemporal frequency variations can aid us in future management andstorm trajectory assessment. In this study the synoptic anemo...

We present high-resolution (∼< 0. 7) ground-based images of the edge-on spiral galaxies NGC 891 (D ∼ 9.5 Mpc) and NGC 4013 (D ∼ 17 Mpc) acquired with the WIYN 3.5-m telescope. These BVI+Hα images reveal complex webs of dusty interstellar material far above the midplanes of both galaxies (0.5 ∼< |z| ∼< 2 kpc) as discussed previously by Howk & Savage (1997). The dusty high-z clouds, visible in ab...

The flow past an infinite vertical isothermal plate started impulsively in its own plane in a viscous incompressible two-phase fluid has been considered by taking into account the viscous dissipative heat. The coupled nonlinear equations governing the flow are solved for fluid and particle phases by finite difference method. The velocity and temperature fields have been shown graphically for G ...
