Artillery Shells over Circinus
The recently identified Circinus Galaxy is the nearest (∼ 4 Mpc) Seyfert 2 galaxy known and we now demonstrate to be one of the best laboratories for studying the effects of nuclear activity3 on the surrounding environment. Here we present new imaging Fabry-Perot observations of Circinus which confirm the existence of an ionization cone in this object but also show for the first time a complex ...

Near{infrared imaging of the Orion Molecular Cloud has revealed that an explosive event occurred in its core within the past 1000 years, ejecting at least a score of dense knots of gas at several 100 km/s.
متن کاملArtillery Strike Effectiveness in the Virtual Battlefield
Artillery plays an irreplaceable role in modern warfare. But due to its huge destructive power, artillery experiment is dangerous and costly. Computer simulation technology uses mathematical models to replace the missile systems and thus avoid accidents and save funds. Based on the trajectory equation model, this paper presents a computer simulation of the projectile distribution. Then, by the ...
