Cataclysmic variables from SRG/eROSITA: new systems from eRASS1
A. D. Schwope, J. Brink, D. A. H. Buckley +12
The paper presents a new sample of 156 cataclysmic variable stars identified from the first eROSITA all‑sky X‑ray survey using a Random Forest classifier and follow‑up spectroscopy…
The SRG/eROSITA All-Sky Survey DR2: Cumulative X-ray catalogues from the first three surveys and multi-wavelength counterparts in the western Galactic hemisphere
M. E. Ramos-Ceja, G. Lamer, M. Salvato +111
The paper presents the second data release of the SRG/eROSITA all‑sky survey, providing catalogues of nearly two million X‑ray sources (point‑like and extended) from the first thre…
A phase-coherent timing solution for the X-ray dim isolated neutron star eRASSU J131716.9-402647
J. Kurpas, A. M. Pires, A. D. Schwope +2
Based on its predominantly thermal X-ray emission and long spin period, the isolated neutron star eRASSU J131716.9-402647 is one of the most promising candidates for membership in…
Isolated neutron star candidates from the fourth generation XMM-Newton catalogues
Adriana M. Pires, Christian Motch, Jan Kurpas +9
X-ray thermally emitting isolated neutron stars (XINSs) are a rare population that provides insights into neutron star cooling, magnetic-field evolution, and Galactic demographics.…
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…
Low-mass stars dominate the hot (0.7 keV) Galactic X-ray emission
G. Ponti, M. C. H. Yeung, G. Stel +12
The circumgalactic medium (CGM) of the Milky Way is composed of a tenuous atmosphere filled with multi-phase plasma, including a warm-hot virialised component. Recent studies sugge…
