ASAS-SN Transients - Ohio State University
WebAbstract We present the discovery of ASASSN-18ey (MAXI J1820+070), a new black hole low-mass X-ray binary (LMXB) discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN). A week after ASAS-SN discovered ASASSN-18ey as an optical transient, it was detected as an X-ray transient by MAXI/GCS. WebApr 4, 2024 · Tweet. We report on recent NICER observations of the transient black hole candidate MAXI J1820+070 (ASASSN-18ey). After spending the initial part of its outburst in the hard state, MAXI J1820+070 made a rapid transition to a softer spectral state in early July (ATel #11820, #11823).NICER monitoring observations show that it remained in this … easiest way to start a tshirt business
