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…

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…

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…

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…

HAWC, VERITAS, Fermi-LAT and XMM-Newton follow-up observations of the unidentified ultra-high-energy gamma-ray source LHAASO J2108+5157

The VERITAS collaboration, C. B. Adams, P. Bangale +142

We report observations of the ultra-high-energy gamma-ray source LHAASO J21085157, utilizing VERITAS, HAWC, Fermi-LAT, and XMM-Newton. VERITAS has collected 40 hours of d…
