X-ray luminous late-type giants: an overlooked population contributing to the Galactic ridge iron line emission
Tong Bao, Gabriele Ponti, Xiao-jie Xu +8
The origin of the highly ionized iron emission (Fe XXV at ) characterizing the Galactic ridge X-ray emission (GRXE) remains a fundamental puzzle in high-energy 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…
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…
A magnetised Galactic halo from inner Galaxy outflows
He-Shou Zhang, Gabriele Ponti, Ettore Carretti +12
Magnetic halos of galaxies are crucial for understanding galaxy evolution, galactic-scale outflows, and feedback from star formation activity. Identifying the magnetised halo of th…
