Using NASA's Chandra X-ray observatory and Australia Telescope Compact Array (ATCA), astronomers have investigated a pulsar wind nebula, dubbed "the Goose," powered by a young pulsar known as PSR J1016–5857. Results of ...
The first demonstration of the laser in 1960 was rapidly followed by the birth of a new research field: nonlinear optics. The unique coherence properties of stimulated emission, the fundamental physical process of laser radiation, ...
Using various space and ground-based observatories, astronomers have inspected flaring activity observed on a blazar known as S5 1803+78. Results of this multi-wavelength study, published April 10 on the arXiv pre-print server, ...
The analysis of astrophysical plasmas is vital in the quest to learn about some of the Universe's most powerful and mysterious objects and events such as stellar coronae and winds, cataclysmic variables, X-ray binaries containing ...
A showcase of evolutionarily designed sensory organs is revealed through high-resolution images of the head of the exclusively cave-dwelling blind salamander, Proteus anguinus. The proteus is an evolutionary masterpiece of ...
The presence of unusually energetic gamma rays seen in some afterglows from intense gamma-ray bursts (GRBs) could be explained by a new mathematical model developed by RIKEN researchers. This finding could help to shed light ...
While methane accounts for about 16% of the abundance in the atmosphere of greenhouse gases—which also include carbon dioxide, nitrous oxide, water vapor—it is more than 25 times better than carbon dioxide at trapping ...
When light hits a material, electrons can be released from this material—the photoelectric effect. Although this effect played a major role in the development of the quantum theory, it still holds a number of secrets: To ...
Engineers working to reverse the proliferation of greenhouse gases know that in addition to reducing carbon dioxide emissions we will also need to remove carbon dioxide from power plant fumes or from the skies. But, what ...
Using the LOw Frequency ARray (LOFAR) and the Very Large Array (VLA), European astronomers have investigated a mysterious diffuse synchrotron source in the galaxy cluster Abell 523. Results of the study, published January ...
