Plasma Dynamics of Radiative Cooling Accretion Flow in AM Herculis with XRISM
Yukikatsu Terada, Kaya Mori, Takayuki Hayashi +14
We present XRISM/Resolve high-resolution X-ray spectroscopy of the prototypical magnetic cataclysmic variable AM Herculis. All satellite lines of highly ionized Fe are fully resolv…
The General Antiparticle Spectrometer (GAPS) Antarctic Balloon Payload
The GAPS Collaboration, Kazutaka Aoyama, Tsuguo Aramaki +65
The General Antiparticle Spectrometer (GAPS) is an Antarctic stratospheric balloon mission designed to provide unmatched sensitivity to low-energy (<0.25 GeV/n) cosmic-ray antiprot…
XRISM spectroscopy of a crowded Galactic center region -- I. Disentangling the sources in the field of view
Maxime Parra, Kai Matsunaga, Shifra Mandel +16
The Galactic center is a complex and crowded region hosting the supermassive black hole Sgr A*, numerous accreting compact objects, and diffuse X-ray emission. This paper presents…
XRISM spectroscopy of a crowded Galactic center region -- II. Narrow emission lines in the Black Hole candidate MAXI J1744-294/Swift J174540.2-290037
Maxime Parra, Shifra Mandel, Kai Matsunaga +13
Narrow, highly ionized X-ray emission lines in black hole low-mass X-ray binaries (BH-LMXBs) are rare and have been observed in only a few sources, during unusual, heavily obscured…
A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
Broadband X-ray observations of the periodic optical source ZTF J185139.81+171430.3 and its identification as a massive intermediate polar
Ren Deng, Kaya Mori, Eric Miao +5
We present X-ray observations of the periodic optical source ZTF J185139.81+171430.3 (hereafter ZTF J1851) by the XMM, NICER and NuSTAR telescopes. The source was initially specula…
