Chikwata chevaongorori chinotungamirwa neYunivhesiti yeUtah, iri muUnited States uye nekubatana kweEuropean Southern Observatory (ESO), iri muChile, nemamwe masangano kubva kuBrazil neArgentina, yakaratidza gomba rakakura kwazvo dema galaxy duku kudarika dzose, kureva muna a Ultra-compact dwarf galaxy.
Zvisinei, maburi matema aya anofungidzirwa kuti ari pakati pezvinenge zvese zvikuru mapoka enyeredzi. Mupfungwa iyi, kuwanikwa kunoratidza kuti mamwe ma ultra-compact dwarf galaxies anogona kuitisa iyi kirasi yemakomba matema, ichiwanzoitika kupfuura zvaimbofungwa.
Saizvozvo, madiki ekupedzisira-compact galaxies ndeimwe yemakobvu masisitimu muCosmos. Huwandu hwekufungidzira hunoratidza kuti mazhinji eaya masisitimu akakura kupfuura zvaidiwa, pamwe semhedzisiro yekumiririrwa kweaya makomba matema makuru. Maererano nezvavakabvisa, buri dema rinoita 15 kubva muzana yehuremu hwose hwegurusvusvu iri uye kunyunguduka kwaigona kunge kuri chinhu chikuru mugwara renzou guru.
Vanyori vanozivisa kuwedzera kukuru kwenhamba ye magaro matema makuru anogona kuburitswa mu cosmos yedu yemuno. Are mapoka enyeredzi Anogona kunge ari "marara" kubva pakusangana nemamwe mapoka enyeredzi.
gomba guru dema
Gomba dema repamusoro-soro igomba dema rine stock yehurongwa hwemamiriyoni kana matiririyoni ehuwandu. sora.
Tichitarisa pane zviri pamusoro, zvidzidzo zvesainzi zvinosimbisa zvakasimba kuti Gwara renzou rine gomba dema rakakura kwazvo pakati peastral centre, yakataurwa. Sagittarius KUTI*. Zvinotaridzwa kuti mazhinji eiyo, anogara yakakura hombe dema gomba pane axis yavo. Muchokwadi, imwe yefungidziro yakagadziridzwa nguva pfupi yadarika ndeyekuti ese ane elliptical uye spiral galaxies ane supermassive dema gomba papakati pawo, izvo zvaizogadzira giravhiti rinodiwa kuchengetedza kubatana.
Chirango chinogoneka mune diki renyeredzi
Pachiyero, gomba dema rakakura kwazvo muaxis ye Ultracompact dwarf galaxy M60-UCD1 yakakura zvakapetwa kashanu pane iyo Milky Way, ine huwandu hwemamiriyoni makumi maviri nerimwe eZuva, uye inoshamisa 21 muzana yehuremu hwakazara. girazi ye140 miriyoni soles. "Zvinoshamisa, nekuti iyo Milky Way yakakura ne500 uye inochajiswa kanopfuura chiuru pane iyo diki yenyeredzi M60-UCD1," Seth akadaro.
Zvinobatanidzwa negurusvusvu renyeredzi
Mune imwe kurongeka kwemazano, pakati pezvinongedzo zvine iro galaxy diki, ndezvi:
Mauto eUnited States of America anokwezvwa neARA Project
Sezvimwechetezvo, Seth akataura kuti zvinotendwa kuti boka guru renyeredzi rine nyeredzi 10.000 60 miriyoni mukati maro, rakapfuura padyo neaxis yegwara renzou rakatokura, iro munyaya ino yatiri kutaura nezveM60, uye mune iyo In. mukufamba kweizvi, nyeredzi dzose nechikamu cherima muchikamu chekunze chegwara renzou zvakatsemuka uye zvikava chikamu cheMXNUMX. Nenzira imwecheteyo, musayendisiti akataura kuti zvichida izvi zvakaitika mamiriyoni gumi emakore apfuura.
Seth anotaura kuti gombe guru renyeredzi M60-UCD1 rinogona kutenderwa, asi haakwanise kutaura kuti riini, kubva kutenderera kwemhepo. darf galaxy pedyo neM60 haiwande. M60 nderimwe remapoka makuru enyeredzi mune izvo vaongorori vanodaidza kuti "cosmos yemuno" uye, kutaura zvazviri, iri kunaya kubva kune rimwe galaxy, inonzi NGC4647. M60 ine simba rakapetwa ka25 pane NGC4647.
Nyaya yeM60
Nokufamba kwemakore, izvi zvaigona kusanganiswa nepakati peM60, ine gomba dema rine utsinye, rine mamiriyoni 4,5 emarudzi akasiyana-siyana ezuva, rakakura nekanopfuura chiuru pane Zuva. gomba gomba supermassive black of our galaxy. Kana izvozvo zvikaitika, gomba dema ratakawana muM60-UCD1 richadhumhana nehutsinye hwakanyanya dema.
Chidzidzo ichi, chakaitwa naSeth nevamwe gumi nevatatu nyanzvi dzenyeredzi, yaitsigirwa nemari neNational Science Foundation iri muUnited States of America. Zvakare neGerman Foundation for Research uye zvakare yakave nekubatana kweGemini Observatory, iyo ine akasiyana masangano esainzi kubva kuChile, Canada, Australia, Brazil neArgentina.
M60-UCD1 ingangoita 54 miriyoni light-years kubva pasi redu kana kuti 320 trillion mamaira, asi galaxy diki rinowanikwa 22.000 light-years chete kubva paaxis ye galaxy M60, iyo iri pedyo nePasi. kutendeuka, iri pakati pe Milky Way.
Vazivi venyeredzi vakaitirana nharo pamusoro pekuti aya ndiwo macores kana kuti hubs emakwara enzou makuru akadzurwa pakadhumhana nemamwe mapoka enyeredzi, kana kuti akasikwa semasumbu epasirese akabiwa, muunganidzwa wenyeredzi dzingangosvika 100.000 200 zvese zvakafuridzirwa pamwechete. Kune anenge mazana maviri mirwi globular muGwara renzou nemakwara enzou akasiyana-siyana ane zviuru.
Mhedziso pamusoro pegwara renyeredzi diki
Boka renyanzvi dzenyeredzi rakaratidza kuti boka duku renyeredzi rine gomba dema guru, richiriita iro boka duku renyeredzi rinozivikanwa kubata chinhu chakadaro zvakasimba kudaro. Kuwanikwa, kunotsanangurwa mujenari 'muzvarirwo' inoratidza kuti maburi matema anotyisa anogona kunge achiwanzoitika pane zvaifungwa pakutanga.
Saizvozvowo, maererano neuchapupu hwemuchadenga Anil Seth, ichi ndicho chinhu chidiki uye chakareruka chatinoziva chinotonga gomba dema super massive. Mupfungwa iyi, nyanzvi dzakashandisa teresikopu yemaziso/infrared iri kuchamhembe kwehemisphere, kunyanya mugomo reMauna Kea, riri muHawaii (United States of America), ndokutora mifananidzo neteresikopu yeHubble cosmic kuratidza kuti musikana anonzi galaxy. M60-UCD1 ine buri dema rine musuru wakafanana neangave mamirioni makumi maviri nerimwe ezuva.
Saizvozvowo, kuwana kwavo kunoratidza kuti mamwe akawanda ma-ultra-compact dwarf nebulae anogona kunge akabata maburi matema akakura, uye madiki iwayo anogona kunge ari marara emapoka makuru enyeredzi akatsemurwa nepakati panguva yekudhumhana nemamwe mapoka enyeredzi.
Zvisinei, hapana imwe nzira inozivikanwa iyo gomba guru rakadaro rinogona kugadzirwa muchinhu chiduku zvakadaro. Uyewo, kune makwara enzou akawanda akafanana iyo inogona kubata nhamba huru yemakomba makuru matema seaya anowanikwa mumasanhu e mapoka enyeredzi semazuva ese.
Saizvozvo, zvakakosha kuziva kuti maburi matema ari kudonha nyeredzi dzine simba regiravhiti zvekuti kunyangwe mwenje unoyeverwa kwavari, zvisinei, izvo zvakavakomberedza zvinogona dzimwe nguva projekiti X-ray jets uye zvimwe zvinomiririra effulgence. Zvinonzwisisika kuti magaro Supermassive blacks, kunyanya avo vane kana kuratidza huremu hunosvika miriyoni yenyeredzi seZuva, vari pakatarisana nemakwara enzou mazhinji.
Chekupedzisira, iro hombe dema gomba harisi mudiki diki renyeredzi chete, kune zvakare iri pakati pe Milky Way, ine huremu hwezuva mamiriyoni mana, asi sezvairi kuchaja sezvairi, ine isingasviki 0,01 muzana youkuru hwakakwana hwe<em>nebula, uhwo hunofungidzirwa kuva hunenge mabhiriyoni makumi mashanu ezuva.
