Precisely measuring velocity of supernova shockwave

more »

Astronomers have precisely measured the expansion velocity of a shockwave of the supernova remnant W44. The remnant is located in the constellation of Aquila, approximately 10,000 light-years away from our solar system. The team observed the high-temperature and high-density molecular gas in the millimeter/submillimeter wave ranges.

New electron beam writer enables next-gen biomedical and information technologies

more »

(Phys.org) —The new electron beam writer housed in the Nano3 cleanroom facility at the Qualcomm Institute is important for electrical engineering professor Shadi Dayeh's two major areas of research. He is developing next-generation, nanoscale transistors for integrated electronics; and he is developing neural probes that have the capacity to extract electrical signals from individual brain cells and transmit the information to a prosthetic device or computer. Achieving this level of signal extraction or manipulation requires tiny sensors spaced very closely together for the highest resolution and signal acquisition. Enter the new electron beam writer.

Zero-dimensional transistor harvests bubble energy wasted during water electrolysis

more »

(Phys.org) —When hydrogen is produced from water during electrolysis, some energy is lost as tiny bubbles. In a new study, researchers have demonstrated that 25-nm transistors—so small that they're considered zero-dimensional (0D)—can be used to transform this lost energy into electric pulses. Millions of these 0D transistors could be used to detect individual bubbles and generate electric pulses at an optimal efficiency, gathering part of the energy lost during electrolysis and making it available for other uses.

Team succeeded in precisely measuring expansion velocity of shockwave of supernova remnant W44

more »

A research team led by Tomoro Sashida and Tomoharu Oka (Keio University) has succeeded in precisely measuring the expansion velocity of a shockwave of the supernova remnant W44. The remnant is located in the constellation of Aquila, approximately 10,000 light-years away from our solar system. The team observed the high-temperature and high-density molecular gas in the millimeter/submillimeter wave ranges. The analysis shows that the expansion velocity of the W44 shockwave is 12.9±0.2 km/sec. In addition, it became clear that the supernova explosion released kinetic energy of (1-3)×1050 erg into the interstellar medium. The energy emitted from the Sun is approximately 3.6 × 1033 ergs/sec. Can you image how enormous amount of energy is released from the supernova explosion? Furthermore, other molecular gas with an extremely high velocity of higher than 100 km/sec was also detected. The origin of this super-high-velocity molecular gas remains unclear at the present time.

Widest, deep starfield ever, using infrared light! posters

Widest, deep starfield ever, using infrared light! posters

Galaxies, Stars and Nebulae series A poster print showing the widest deep view of the sky ever made to date, using infrared light and ESO's VISTA telescope.
This particular image comes from the UltraVISTA survey and reveals more than 200 000 galaxies. To make it, ESO’s VISTA telescope was been trained on the same patch of sky repeatedly to slowly accumulate the very dim light of the most distant galaxies.
In total more than six thousand separate exposures with a total effective exposure time of 55 hours, taken through five different coloured filters, were combined to create this picture.
Apart from a handful of blue-looking stars, everything in this picture is a galaxy, billions of light years away. The tiny red dots are galaxies so remote that the light we see from them started its journey shortly after the Universe itself formed - wow!

A Starburst Galaxy - Messier 82 (Cigar Galaxy) Galaxy S3 Cover

A Starburst Galaxy - Messier 82 (Cigar Galaxy) Galaxy S3 Cover

Galaxies, Stars and Nebulae series This mosaic image of the magnificent starburst galaxy, Messier 82 (aka Cigar Galaxy) is a really sharp wide-angle view of M82. It is a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions where young stars are being born 10 times faster than they are inside in our Milky Way Galaxy.
