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…

On the baryon budget in the X-ray-emitting circumgalactic medium of Milky Way-mass galaxies

Yi Zhang, Soumya Shreeram, Gabriele Ponti +6

Recent observations with SRG/eROSITA have revealed the average X-ray surface brightness profile of the X-ray-emitting circumgalactic medium (CGM) around Milky Way (MW)-mass galaxie…

The Advanced X-ray Imaging Satellite (AXIS) Community Science Book

Michael Koss, Nafisa Aftab, Steven W. Allen +395

The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…

Unveiling the soft X-ray source population towards the inner Galactic disk with XMM-Newton

Tong Bao, Gabriele Ponti, Frank Haberl +5

Across the Galactic disk lies a diverse population of X-ray sources, with the fainter end remaining poorly understood due to past survey sensitivity limits. We aim to classify and…

The X-ray luminosity function of stars observed with SRG/eROSITA

Nicola Locatelli, Gabriele Ponti, Enza Magaudda +1

Background diffuse X-ray emission is contributed in large part by the emission of point sources not individually resolved. While this is established since decades for the contribut…

A sample of ionised Fe line-emitting X-ray sources in the inner Galactic disc

Samaresh Mondal, Gabriele Ponti, Tong Bao +4

Previous studies suggest that the Galactic diffuse X-ray emission is composed of unresolved point sources, primarily mCVs. However, nearby mCVs have a much lower 6.7 keV line equiv…
