As one of its contributiosn to the Around the World in 80 Telescopes webcast, part of the 100 Hours of Astronomy fiesta last weekend, NASA released a great set of movies made from data gathered by the Fermi gamma-ray observatory. It shows a view of the full sky at gamma-ray wavelengths taken between August and October last year, with gamma ray bursts popping up in quick flashes. Very nice!
Detecting supersymmtric dark matter
A very interesting paper was published in last week’s issue of Nature – I blogged about it before after reading the NASA press release. It’s wasn’t all that helpful without reading the actual paper but the cosmic ray – dark matetr link caught my attention.
Just today a conference paper (i.e. not peer-reviewed) appeared on astro-ph about some preliminary results from PAMELA – another cosmic ray detector that focuses on antiparticles (positrons and antiprotons). Recall that PAMELA was the source of some controversy earlier this year. Another paper on PAMELA data was posted on astro-ph back in October, it’s listed as being submitted to Nature so again, not reviewed yet. But perhaps another cosmic rays Nature paper soon, and there’s certainly a lot of buzz!
I had a read through these papers and some background stuff – it’s something I didn’t know much about and it’s very cool. Cosmic rays: inneresting akshually!
After diligently setting my watch for the NASA news telecon and getting comfortable on the couch, I realised that I couldn’t listen to the thing on an iPhone and had left my laptop at work (happens about once a month, good call woman). Doh.
