Stars and gas mix in a  violent process, creating new stars and adding mass to the black hole in  the centre.\u201d Astronomer and physicist Akira Endo describes the  processes as if he had witnessed them himself. <!--more-->But in fact, knowledge  about the universe at the age of between two and seven billion years old  is limited, owing to a lack of satisfactory observations. Dust clouds  hide collisions from the view of optical telescopes, while light from  the stars heats the dust, causing it to emit sub-millimetre waves. Endo  argues that much can be learned from studying this radiation, if that is  you are able to measure its wavelength. This is the key to the  &#8216;redshift&#8217; (the Doppler-like frequency shift due to the light source&#8217;s  velocity) of the radiation, and hence to the age of the observed  galaxies. \u201cCurrent cameras produce number counts of sub-millimetre  galaxies\u201d, says Endo. \u201cBut they cannot determine the redshifts necessary  to convert number counts into a star formation history.\u201d<\/p>\n<p>The  reason for this is simply because at present no broadband spectrometer  for sub-millimetre radiation exists. Endo has therefore proposed to  develop such a spectrometer at the faculty of Applied Sciences, in  collaboration with astronomers from Leiden University and the  Netherlands Institute for Space Research (SRON). The Netherlands  Organisation for Scientific Research (NWO) has funded the project with a  grant worth 250,000 euro, and the Japan Society for the Promotion of  Science has contributed another 100,000 euro.<\/p>\n<p>The superconducting  detector that Endo plans to develop is called a kinetic inductance  detector (or KID) and consists of an antenna and a tuneable microwave  resonator. With 10,000 KIDs, each tuned to a subsequent frequency, Endo  hopes to analyse the radiation coming from those early galaxies at  frequencies ranging from 300 to 1000 gigahertz. By the time this  three-year project ends, Endo hopes to have conducted the first  measurements himself.<\/p>\n<p><a href=\"http:\/\/www.delta.tudelft.nl\/nl\/wetenschap\/astronomer-wins-veni-grant\/21692\" target=\"_blank\">Link<\/a> to article in Delta<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr. Akira Endo has been awarded a Veni grant to develop a detector for studying the evolution of the early universe.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3,6],"tags":[51,52,190,417],"class_list":["post-1322","post","type-post","status-publish","format-standard","hentry","category-articles","category-delta","tag-astronomy","tag-asttron","tag-galaxies","tag-sub-millimetre"],"_links":{"self":[{"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=\/wp\/v2\/posts\/1322","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1322"}],"version-history":[{"count":0,"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=\/wp\/v2\/posts\/1322\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1322"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1322"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.joswassink.nl\/insight\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1322"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
