Widefield ASKAP L-Band Legacy All-Sky Blind Survey

Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) [1][2][3] bụ nyocha ọgbọ na-esote nke 21 cm redio sitere na Hydrogen na-anọpụ iche (HI) na Local Universe.  Ọ bụ Australian Square Kilometer Array Pathfinder (ASKAP) telescope na-akwado ya, WALLABY ga-enyocha ụzọ atọ n'ụzọ anọ nke mbara igwe n'elu -90 ° ruo +30 ° ruo redshift nke 0.26. Ọ ga-enwe mkpebi nkuku nke 30 arcsec na mmetụta nke 1.6 mJy /beam na ọwa 4 km / s ọ bụla.  A na-atụ anya na WALLABY ga-achọpụta ihe dị ka ụyọkọ kpakpando Narị puku ise na redshift nke 0.05, na nkezi nke ihe dị ka 200 Mpc. Ihe mgbaru ọsọ sayensị nke WALLABY gụnyere:  

  • ọnụ ọgụgụ nke ụyọkọ kpakpando ndị jupụtara na gas na nso nke Local Group;
  • ọmụmụ nke njirimara HI nke ụyọkọ kpakpando, ìgwè na ụyọkọ, gụnyere mmetụta nke gburugburu ebe obibi na evolushọn ụyọkọ.

Akụkọ ihe mere eme dezie

Ndị otu B. S. Koribalski na L. Staveley-Smith duziri atụmatụ ọrụ WALLABY na 2009. ASKAP họọrọ ya na abụọ kachasị elu n'ime ọrụ nyocha sayensị iri, yana Koribalski na Staveley-Smith bụ ndị isi nyocha. Koribalski kwụsịrị n'afọ 2019. Ugbu a, Lister Staveley-Smith bụ onye nyocha isi, Karen Lee-Waddell bụ ọkà mmụta sayensị na-arụ ọrụ, na Tobias Westmeier bụ onye njikwa ọrụ .. Ndị otu WALLABY nwere ugbu a karịa ndị otu one hundred and fifty. [4] ugbu a.

Nsonaazụ sayensị mbụ dezie

E bipụtara ọtụtụ nsonaazụ sayensị site na nchọpụta WALLABY Early Science. Ihe ndị dị mkpa gụnyere nchọpụta atọ nke ìgwè ụyọkọ kpakpando, [5] [6] [7] na nyocha abụọ zuru ezu nke ụyọkọ ụyọkọ ndị dị nso. [8] [9]

Nnyocha ụgbọelu WALLABY dezie

N'ịkwadebe maka nyocha WALLABY zuru oke, nke a na-atụ anya ịmalite n'afọ 2021, WALLAPY mere nyocha nyocha n'afọ 2020, nke nwere mpaghara nyocha atọ na ntụziaka nke Hydra, NGC 4636 na Norma. A hụla data niile n'ụzọ zuru ezu, a na-emekwa ka ogige Hydra dị mma ma see ya, na-eduga na ntọhapụ mbụ nke data maka ihe fọrọ nke nta ka ọ bụrụ nchọpụta HI 150 na ntụziaka nke ụyọkọ Hydra. Ndị otu sayensị WALLABY na-enyocha data Hydra ugbu a, a na-atụkwa anya akwụkwọ sayensị mbụ na ngwụcha 2020.   [citation needed]
