1 and 3), all but a few associated with active galaxies of the blazar class. These discoveries comprise the single largest category of gamma-ray source detected with EGRET and are all the more noteworthy in that prior to the launch of the CGRO only one such gamma-ray AGN was known, ...
When the focus light falls on your subject and your subject is in focus, take a test shot to check your snoot is in the correct position, and when it is, tighten the clamps of your strobe arms and you are ready to go! The problem comes in when you find a differently sized subject ...
In 2024 the Perseid meteor shower was active between 17 July and 24 August, with the number of meteors (also known as shooting stars) increasing every night until it reached its peak, after which it then tailed off. This year the peak was on the night of the 12th and before dawn on 1...
This chapter presents a simulation approach for Time-of-Flight cameras, which is able to retain all light interactions with the objects of the scene within the geometric optics model. In particular, the method includes a physical description of direct and diffuse reflection, refraction, and Mie-sc...
One sample also features the letter X written without any ink. It is written with the backside of a ballpen, so that the image shows only the deformation of the paper due to the pressure typically applied during writing. Each sample consists of only one sheet of paper with the letters ...
Keywords: attosecond pulses; X-ray optics; plasma-based X-ray laser; strong optical field; Stark effect; high-order harmonic amplification1. Introduction The beginning of the 21st century was marked by the emergence and rapid development of attosecond physics—an interdisciplinary field of research ...
In the long run, a cooling system shall be implemented, for which the mechanical stability of the optics must be carefully assessed. 4. Wavefront Propagation Simulation Performance of the hybrid SDL was evaluated by the front-to-end simulation. For this purpose, wavefront propagation was ...
Hence, TimeMaxyne has been demonstrated to be capable of shot-noise limited, time-resolved imaging, at time resolutions of 50 ps and below, only limited by the X-ray pulse widths of the synchrotron. Keywords: time-resolve X-ray microscopy; pump-probe data acquisition; magnetic imaging...

Additionally, according to the presented data for comparing the same film surface (see Figure 7) taken with an optical microscope and a scanning electron microscope, the density of the observed tracks is very dependent on the used optics, which allows detecting tracks. In the case of ...
