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 VLA Study of Newly-Discovered Southern Latitude Non-Thermal Filaments in the Galactic Center: Polarimetric and Magnetic Field Properties
Dylan M. Pare, Cornelia C. Lang, Mark R. Morris
A population of structures unique to the Galactic Center (GC), known as the non-thermal filaments (NTFs), has been studied for over 40 years, but much remains unknown about them. I…
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…
Periodicity from X-ray sources within the inner Galactic disk
Samaresh Mondal, Gabriele Ponti, Tong Bao +9
For many years, it has been claimed that the Galactic ridge X-ray emission at the Galactic Center (GC) is truly diffuse in nature. However, with the advancement of modern X-ray sat…
X-rays from a Central "Exhaust Vent" of the Galactic Center Chimney
Scott C. Mackey, Mark R. Morris, Gabriele Ponti +2
Using deep archival observations from the Chandra X-ray Observatory, we present an analysis of linear X-ray-emitting features located within the southern portion of the Galactic ce…
Ionized regions in the central arcsecond of NGC 1068. YJHK spatially resolved spectroscopy
P. Vermot, B. Barna, S. Ehlerová +3
Context. Several bright emission line regions have been observed in the central 100 parsecs of the active galaxy NGC 1068. Aims. We aim to determine the properties and ionization m…
Fifteen years of XMM-Newton and Chandra monitoring of Sgr A*: Evidence for a recent increase in the bright flaring rate
G. Ponti, B. De Marco, M. R. Morris +13
We present a study of the X-ray flaring activity of Sgr A* during all the 150 XMM-Newton and Chandra observations pointed at the Milky Way center over the last 15 years. This inclu…
On the Fe K absorption - accretion state connection in the Galactic center neutron star X-ray binary AX J1745.6-2901
G. Ponti, S. Bianchi, T. Munoz-Darias +17
AX J1745.6-2901 is a high-inclination (eclipsing) neutron star Low Mass X-ray Binary (LMXB) located less than ~1.5 arcmin from Sgr A*. Ongoing monitoring campaigns have targeted Sg…
