Lavxias teb sab ART-XC telescope nyob rau hauv lub Spektr-RG chaw soj ntsuam tau pib nws txoj kev tshawb fawb thaum ntxov. Thaum lub sij hawm thawj scan ntawm lub hauv paus "bulge" ntawm lub Milky Way galaxy, ib tug tshiab X-ray qhov chaw, hu ua SRGA J174956-34086.
Nyob rau tag nrho lub sijhawm ntawm kev soj ntsuam, tib neeg tau tshawb pom txog ib lab qhov chaw ntawm X-ray hluav taws xob, thiab tsuas yog kaum ob ntawm lawv muaj lawv tus kheej lub npe. Feem ntau, lawv muaj npe sib xws, thiab lub hauv paus ntawm lub npe yog lub npe ntawm cov neeg soj ntsuam uas pom qhov chaw. Tom qab tshawb pom qhov chaw tshiab, cov kws tshawb fawb yuav tsum tau tshawb fawb txuas ntxiv uas yuav pab txiav txim siab nws qhov xwm txheej. Lub hauv paus tuaj yeem yog qhov nyob deb quasar lossis lub zeem muag lub hnub qub nrog lub hnub qub neutron lossis qhov dub.
Txhawm rau txheeb xyuas qhov khoom kom raug, cov kws tshawb fawb pom lub hauv paus ntawm hluav taws xob los ntawm lwm lub tsom iav. Lub Neil Gehrels Swift X-ray telescope, XRT, uas muaj kev daws teeb meem zoo dua, tau siv. Cov hluav taws xob hluav taws xob hauv cov hluav taws xob xoo hluav taws xob tau dhau los ua dimmer dua li cov X-rays nyuaj. Qhov no tshwm sim yog tias qhov chaw hluav taws xob nyob tom qab huab cua ntawm cov hnub qub thiab cov plua plav.
Nyob rau hauv lub neej yav tom ntej, cov kws tshawb fawb yuav sim kom tau txais cov khoom siv kho qhov muag uas yuav ua rau nws muaj peev xwm txiav txim siab qhov xwm txheej ntawm qhov chaw kuaj X-ray. Yog tias qhov no ua tsis tiav, ART-XC yuav txuas ntxiv mus tshawb xyuas thaj chaw kom pom cov khoom tsis muaj zog. Txawm hais tias qhov kev ua haujlwm yuav los tom ntej no, nws tau sau tseg tias Lavxias ART-XC telescope twb tau tso nws cov cim hauv cov ntawv teev npe ntawm X-ray qhov chaw.
