Neke atu i te 900 ngā Pulsar Hou i Kitea: Te Whakamahinga o te Hangarau Reera i roto i te Karu Whānui FAST o Haina

Kua miharo anō te ao ki tētahi kitenga hou i te FAST Telescope o Haina, he karu whakaata porowhita nui e 500 mita te whānui, kei te kawanatanga o Guizhou. Nō nā tata nei, kua angitu a FAST ki te kite i ngā pulsar hou neke atu i te 900. Ehara i te mea ka whakarei ake i te mara o te whetū arorangi anake tēnei whakatutukitanga, engari ka tukuna hoki he tirohanga hou mō ngā takenga mai me te whanaketanga o te ao whānui.

Hei hopu i ngā ngaru reo irirangi ngoikore mai i ngā pito tawhiti o te ao tūroa — ngā ngaru e pupuri ana i ngā mea ngaro o ngā tupua tawhiti, ngā pulsar, me ngā ngota ira-whetu — ka whakawhirinaki a FAST ki tētahi raupapa o ngā hangarau matatau.

Te Tūranga Hiranga o te Hangarau Reera i roto i te Hanganga a FAST

Te Hanga Tika

Ko te mata whakaata o FAST he mano tini ngā panera takitahi, ā, he mea nui te tūnga me te whakatikatika tika o ēnei panera mō ngā tirohanga tairongo-teitei. He mahi nui tā te hangarau taiaho i roto i tēnei tukanga. Mā te tapahi me te tohu taiaho tika, ka whakarite kia tika te hanga o ia wāhanga, kia mau tonu te āhua me te pumau o te mata whakaata.

Te Ine me te Tūnga

Hei whakatutuki i te whāinga me te arotahi tika, ka whakamahia te hangarau ine taiaho hei ine me te whakatika i ngā tūranga o ngā wae whakaata. Mā te whakamahi i ngā pūnaha aroturuki me te whāiti taiaho ka tino whakarei ake i te tika me te whai huatanga o ngā tirohanga.

Te Whakarewa me te Hononga

I te hanganga o FAST, i whakamahia te hangarau whakarewa laser hei hono i ngā taura rino maha me ngā hanganga tautoko. Mā tēnei tikanga whakarewa tino tika, whai hua hoki ka mau tonu te pumau me te pono o te hanganga o te karu tiro.

Ngā Whakamatao Taiaho Te Whakapūmau i te Mahi Pūmau o ngā Taputapu Reihana

I roto i te whakahaerenga o te FAST, he mahi nui tā ngā pouaka whakamatao laser. Mā rātou e whakahaere te pāmahana o te taiao mahi o ngā taputapu laser mā te wai whakamatao e rere ana, kia pai ai te mahi a ngā taputapu. Mā tēnei ka oati te tika o te tukatuka me te ine laser, ka whakarei ake i te pumau me te whai huatanga o te pūnaha.

Ko te hanganga me te whakahaere o FAST ehara i te mea e whakaatu ana i te tūranga nui o te hangarau taiaho i roto i te arorangi o ēnei rā, engari he tohu anō hoki i tētahi upoko hou i roto i te tūhuratanga a te tangata i te ao whānui. I a FAST e haere tonu ana tana mahi me tana rangahau, e matapaetia ana ka hurahia e ia ētahi atu mea ngaro o te ao, ka akiaki i ngā whanaketanga i roto i te arorangi me ngā mara pūtaiao e pā ana.
