Hubble Abona Flash Itangaje Hagati ya Galagisi

Mugihe ikirere nijoro gishobora kugaragara gituje (kandi ni cyiza cyane), isanzure yuzuyemo ibisasu biturika kandi bigongana. Mubidakunze kubaho muribi bihe byinzibacyuho harimo ibyo bita Luminous Byihuta Ubururu Optical (LFBOTs), bimurika cyane mumucyo wubururu kandi bigashira nyuma yiminsi mike. Ibi bintu byinzibacyuho bigaragazwa gusa na telesikopi ikomeza gukurikirana ikirere. Hifashishijwe icyuma cyitwa Hubble Space Telescope, itsinda mpuzamahanga ry’abahanga mu bumenyi bw’inyenyeri baherutse kureba LFBOT iri hagati yinjeje ebyiri, ahantu ha nyuma bari biteze ko bazabona imwe.

Iri tsinda ryari riyobowe n’umuhanga mu bumenyi bw’inyenyeri Ashley Chrimes, Umushakashatsi w’ikigo cy’ibihugu by’Uburayi gishinzwe ubushakashatsi, wahoze mu kigo cy’imibare y’imibare n’ubumenyi bw’ibinyabuzima (IMAPP) muri kaminuza ya Radboud. Yifatanije na bagenzi be bo muri IMAPP, Ikigo cya 3SRON cyo mu Buholandi gishinzwe ubushakashatsi ku kirere, Cosmic Dawn Centre (DAWN), Ikigo cya Niels Bohr, Ikigo cya Gravitational Wave Astronomie, Observatoire ya Afurika y'Epfo, hamwe na kaminuza nyinshi n'ibigo by'ubushakashatsi. Urupapuro rusobanura ibyo babonye ruzashyirwa ahagaragara mu kwezi kwa buri kwezi kwa Royal Astronomical Society.

LFBOT yambere yagaragaye muri 2018 (AT2018cow) na Asteroid-Terrestrial-impact-Last Alert Sisitemu (ATLAS). Ibi birori byiswe "Inka," byari byiza cyane inshuro 10-100 kurenza supernova isanzwe kandi byabereye muri galaxy hafi miriyoni 200 zumucyo (miriyoni 60 parsec). Kuva icyo gihe, abahanga mu bumenyi bw'ikirere bavumbuye LFBOT ku gipimo kingana n'umwaka ku mwaka, bityo bake gusa ni bo bazwi, kandi ni bike cyane bizwi kuri bo. Mugihe inyigisho nyinshi zerekeye impamvu zishobora kubaho zibaho, Hubble aherutse kuvumbura yatumye iki kintu kirushaho kuba amayobera.
