Photoionization of Disk Winds

The disk-wind model suggests that the broad emission lines of a quasar are emitted from the surface of the accretion disk feeding the central black hole. In this paper, we assume that a line-driven wind emerges from the illuminated face of the disk and calculate the line emission produced by this wind. The location and mass-loss rate of the wind are determined by the physics of the line driving...

The Winds of Change.

Distance learning and other modes of online instruction, such as those offering hybrid models, are closely linked to the manner that new technologies are tested, implemented and evaluated. This paper works from an understanding of where technologies supporting instruction have converged in 2002, and suggests that by taking an evolutionary view of technology we will improve the design of instruc...

Theory of Pulsar Winds

I discuss recent work on the nature of relativistic winds from Rotation Powered Pulsars, on the physics of how they transport energy from the central compact object to the surrrounding world, and how that energy gets converted into observable synchrotron emission.

The Winds of Change

Pakistani women are increasingly making an impact at the international level though it will take time for this to make a difference in the plight of women at home. According to a recent poll conducted by the Thomson Reuters Foundation, Pakistan is the third most dangerous country for women, preceded only by Afghanistan and the Congo. With domestic violence, dismal healthcare and brutal poverty ...
