Amanda Weltman (amụrụ n'afọ 1979) bụ onye sayensị sayensị nke South Africa. A maara ya nke ọma maka ide usoro akwụkwọ na-atụ aro "cameleon gravity" iji kọwaa ịdị adị nke ike ọchịchịrị. Ọ bụ Prọfesọ na Onye isi nchọpụta South Africa ugbu a na Mahadum Cape Town.

Agụmakwụkwọ na nchọpụta mbụ[dezie | dezie ebe o si]

Amanda Weltman bu ụzọ mara physics mgbe ọ bụ nwa akwụkwọ na Mahadum nke Cape Town . [1] [1]'ịkọwa mmasị ya n'ịbụ onye na-ahụ maka physics, o kwuru na "ịghọta ụzọ eluigwe na ala si arụ ọrụ bụ naanị ọrụ kachasị mma onye ọ bụla nwere ike inwe".

N'afọ 2007, Weltman gụsịrị Ph.D. ya na physics na Mahadum Columbia na New York. [2] bụ onye na-ahụ maka physics bụ Brian Greene lekọtara ya. [3] mekwara nnyocha post-doctoral na Mahadum Cambridge dị ka akụkụ nke Centre for Theoretical Cosmology nke onye physics Stephen Hawking na-achị. Ọ bụ onye nduzi nke otu High Energy Physics, Cosmology na Astrophysics Theory nke o guzobere na 2018.

Ndụ onwe onye[dezie | dezie ebe o si]

A mụrụ Weltman na 1979 [4] na Cape Cod, Massachusetts, ma soro ndị mụrụ ya kwaga South Africa mgbe ọ dị ọnwa abụọ. [5] [2][5] nọrọ n'oge ọ bụ nwata na Johannesburg na Cape Town. [5] bụ onye na-eme egwuregwu mmega ahụ na asọmpi mgbe ọ bụ nwatakịrị.

Ya na di ya Jeff Murugan bi, onye bụ onye na-akụzi ihe na mahadum ahụ. Ọ zutere ya na 1997, [1] ma nwee ụmụ atọ. [2] [3] [1] kwuru na obi dị ya ụtọ ịzụlite ya n'ezinụlọ na-enweghị Echiche nwoke na nwanyị, nakwa na ihe mgbochi ndị ụmụ nwanyị sayensị chere ihu na-emerụ ahụ karịsịa mgbe ha mere n'ụdị echiche ụmụaka na-ahụ. [1] na di ya na-ewe oge ezumike iji lekọta ụmụ ha, ma na-agakarị nzukọ dị ka ezinụlọ.

Nnyocha na ọrụ[dezie | dezie ebe o si]

[1] maara Weltman mgbe ya na Justin Khoury dere akwụkwọ 2004 nke akpọrọ "Chameleon Cosmology", nke tụpụtara echiche iji kọwaa ike ọchịchịrị. [1] bụ nwa akwụkwọ gụsịrị akwụkwọ na Mahadum Columbia n'oge ahụ. A na-atụ aro ike gbara ọchịchịrị dị ka nkọwa maka mgbasawanye ngwa ngwa nke eluigwe na ala. Khoury na Weltman tụrụ aro ịdị adị nke ike ọhụrụ nke mere ka mgbasawanye a, nke gbanwere dabere na gburugburu ebe obibi ọ nọ. [6][1] ga-abụ nke na-adịghị ike mgbe ụmụ irighiri ihe jikọtara ọnụ, ma sie ike mgbe ha dị anya. [7] mere, echiche ahụ na-atụ aro na n'ógbè ebe ihe dị oke, ike chameleon siri ike ịchọpụta; mana n'ọ́tụ̀ ndị tọgbọrọ n'efu, ọ na-arụ ọrụ iji chụpụ ihe dị iche iche ma gbasaa eluigwe na ala.

Echiche nke ikike ndọda nke chameleon [8]-akpali akpali n'akụkụ ụfọdụ n'ihi na enwere ike ịnwale ya n'ọtụtụ gburugburu ebe gụnyere na ule ụlọ nyocha. A na-eme nchọpụta mbụ maka ike gbara ọchịchịrị na ụlọ nyocha ahụ dị ka nchọpụta maka chameleons. N'afọ 2007, Weltman sonyeere otu ndị na-eme nnwale na Fermilab na nnwale GammeV nke e mere iji chọọ axion dị ka ụmụ irighiri ihe. [9] debere ókèala mbụ na parameters nke ikike ndọda nke chameleon site na nnwale a na 2008. [1] [10] rụgharịrị nnwale ahụ ma wughachi ya dị ka ihe nchọpụta chameleon, GammeV CHASE (Cameleon Afterglow Search Experiment), [1] na nsonaazụ mbụ na-egbochi ike ọchịchịrị chameleon na 2010. Ndị a bụ nnwale mbụ nke ụdị ha ma nwee ike itinye oke nnwale mbụ na echiche ahụ. Ọrụ [11] butere ụzọ ọhụrụ nke nnwale ụlọ nyocha na-achọ ike ndọda nke chameleon, ma ọ bụ ike ọchịchịrị n'ozuzu ya, na ụlọ nyocha ahụ. A kọwawo echiche nke Khoury na Weltman mepụtara dị ka nke na-eduga na "akụkụ niile na cosmology na physics nnwale". A kọwawo ọrụ ya dị ka ịga n'ihu nke ọrụ Albert Einstein.

N'afọ ndị na-adịbeghị anya, Weltman enyewo aka dị ukwuu na astrophysics, ọkachasị n'ọhịa nke Fast Radio Bursts (FRBs), [12] ihe omimi millisecond-long bursts nke ebili mmiri redio sitere na ụyọkọ kpakpando ndị dị anya. Otu [13]'ime onyinye ya ndị bụ isi ebe a bụ ndepụta zuru oke nke ụdị echiche dị iji kọwaa ndị nne na nna FRB. N'etiti ọtụtụ onyinye ndị ọzọ dị mkpa ọ nyere na physics FRB, ọ tụpụtara ule ọhụrụ nke ihe nlereanya nke FRBs n'ihi mmetụta Gertsenshtein-Zeldovich (GZ) nke na-akọwa otu ebili mmiri na-agafe pulsar magnetosphere nwere ike isi gbanwee (n'akụkụ ụfọdụ) na radiation electromagnetic. Otu ihe ọhụrụ nke ihe nlereanya a bụ amụma ya na FRBs ga-esonyere ebili mmiri na-aga n'ihu nke ndị na-achọpụta ebili mmiri n'ọdịnihu nwere ike ịchọpụta.

Weltman na-arụ ọrụ dị mkpa na Hydrogen Intensity na Real-time Analysis eXperiment (HIRAX) nke a na-ewu ugbu a na South Africa.

Mmekọrịta ọha na eze[dezie | dezie ebe o si]

Na mgbakwunye na okwu agụmakwụkwọ, Weltman na-enye nkuzi ọha na eze banyere cosmology, astrophysics na sayensị n'ozuzu. O dere ọtụtụ isiokwu maka ọha na eze, [14] [15] maka Nature News and Reviews [16] ma nye ajụjụ ọnụ n'ọtụtụ isiokwu metụtara sayensị, cosmology na astrophysics maka mgbasa ozi dịgasị iche iche.

Weltman ejerela ndị ọkà mmụta sayensị ozi, ọkachasị na South Africa, site na ọrụ idu ndú na bọọdụ mba na ụlọ akwụkwọ. A họpụtara ya na South African Young Academy of Science na 2012 ma họpụta ya na ndị isi ya na 2015-2016.

Weltman jere ozi na Steering Board maka National Institute of Theoretical Physics nke South Africa kemgbe 2015, ma na-eje ozi ugbu a na steering board maka National Institute for Theoretical and Computational Sciences.

Weltman jere ozi na Steering Board maka East African Institute for Fundamental Research na Rwanda kemgbe 2018.
