MAXI and NuSTAR observations of the faint X-ray transient MAXI J1848-015 in the GLIMPSE-C01 Cluster

Sean N. Pike, Hitoshi Negoro, John A. Tomsick +14

We present the results of MAXI monitoring and two NuSTAR observations of the recently discovered faint X-ray transient MAXI J1848-015. Analysis of the MAXI light-curve shows that t…

Discovery and Long-term Broadband X-ray monitoring of Galactic Black Hole Candidate MAXI J1803-298

Megumi Shidatsu, Kohei Kobayashi, Hitoshi Negoro +11

We report the results from the broad-band X-ray monitoring of the new Galactic black hole candidate MAXI J1803298 with the MAXI/GSC and Swift/BAT during its outburst. After the…

Discovery of a strong 6.6 keV emission feature from EXO 1745248 after the superburst in 2011 October

Wataru B. Iwakiri, Motoko Serino, Tatehiro Mihara +4

We discover an unidentified strong emission feature in the X-ray spectrum of EXO 1745248 obtained by RXTE at 40 hr after the peak of a superburst. The structure was centered at…

Optical Variability Correlated with X-ray Spectral Transition in the Black-Hole Transient ASASSN-18ey = MAXI J1820+070

Keito Niijima, Mariko Kimura, Yasuyuki Wakamatsu +49

How a black hole accretes matter and how this process is regulated are fundamental but unsolved questions in astrophysics. In transient black-hole binaries, a lot of mass stored in…

On the nature of the anomalous event in 2021 in the dwarf nova SS Cygni and its multi-wavelength transition

Mariko Kimura, Shinya Yamada, Nozomi Nakaniwa +20

SS Cyg has long been recognized as the prototype of a group of dwarf novae that show only outbursts. However, this object has entered a quite anomalous event in 2021, which at firs…
