XMM-Newton Resolves Parsec-scale X-ray Jets in the PeVatron Microquasar V4641 Sgr
Naomi Tsuji, Caterina Tresoldi, Kaya Mori +34
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of deg…
Distinct Velocity Components in the Absorption Lines of the Neutron Star X-ray Binary AX J1745.6-2901
Kai Matsunaga, Maxime Parra, Yutaro Nagai +10
Accretion disks in X-ray binaries regulate mass transfer onto compact objects and drive radiative and kinetic feedback to their surroundings. Here we report X-ray spectroscopy of t…
Dense, multi-phase accretion disk atmosphere in the low-luminosity state of black hole transientV4641 Sgr
Zuobin Zhang, Rob Fender, James H. Matthews +11
We present soft X-ray spectroscopy of the black-hole X-ray binary V4641~Sgr with the \textit{XMM-Newton} Reflection Grating Spectrometer (RGS). The RGS spectrum shows narrow emissi…
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…
XRISM spectroscopy of a crowded Galactic center region -- III. S, Ar and Ca ISM Absorption Features in the spectrum of MAXI J1744-294
Efrain Gatuzz, Maxime Parra, Muhammet F. Hasoglu +7
We present a comprehensive study of X-ray absorption by sulfur (S), argon (Ar), and calcium (Ca) in the interstellar medium (ISM) along the line of sight to the low-mass X-ray bina…
A high-resolution X-ray view of the ultra-fast outflow in MAXI J1810-222
C. Pinto, M. Del Santo, A. D'Aì +10
In previous work, it was reported that the Galactic black hole candidate MAXI J1810-222 exhibited a notable absorption spectral feature at around 1 keV in low-resolution X-ray spec…
X-ray Spectroscopy of Disk Winds in Black Hole X-ray Binaries
Megumi Shidatsu, Maxime Parra
Powerful outflows along the accretion disk, known as disk winds, are sometimes launched in black hole X-ray binaries. These winds often manifest themselves in X-ray spectra as blue…
