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…

Deep XMM-Newton observation reveals hot gaseous outflow in NGC 5746

Roman Laktionov, Manami Sasaki, Jörn Wilms

We present a deep XMM-Newton observation of the massive, edge-on galaxy NGC 5746. The total exposure time of 250 ks provides unprecedented sensitivity to study the diffuse hot gas…

The SRG/eROSITA diffuse soft X-ray background. I. The local hot bubble in the western Galactic hemisphere

Michael C. H. Yeung, Gabriele Ponti, Michael J. Freyberg +10

The SRG/eROSITA All-Sky Surveys (eRASSs) combine the advantages of complete sky coverage and the energy resolution provided by the charge couple device and offer the most holistic…

Morphological Evidence for the eROSITA Bubbles Being Giant and Distant Structures

Teng Liu, Andrea Merloni, Jeremy Sanders +13

There are two contradictory views of the eROSITA bubbles: either a 10 kpc-scale pair of giant bubbles blown by the Galactic center (GC), or a 100 pc-scale local structure coinciden…

The first all-sky survey of star-forming galaxies with eROSITA: Scaling relations and a population of X-ray luminous starbursts

E. Kyritsis, A. Zezas, F. Haberl +11

We present a study of X-ray normal galaxies using data from the first all-sky scan of the eROSITA X-ray survey. eRASS1 provides the first unbiased X-ray census of normal galaxies a…

Discovery of the Goat Horn complex: a deg diffuse X-ray source connected to radio loop XII

Nicola Locatelli, Gabriele Ponti, Andrea Merloni +7

A dozen of patches of polarized radio emission spanning tens of degrees in the form of coherent and stationary loops are observed at radio frequencies across the sky. Their origin…

eROSITA narrowband maps at the energies of soft X-ray emission lines

Xueying Zheng, Gabriele Ponti, Nicola Locatelli +10

[abridged] Hot plasma plays a crucial role in regulating the baryon cycle within the Milky Way, flowing from the energetic sources in the Galactic center and disc, to the corona an…

Broadband maps of eROSITA and their comparison with the ROSAT survey

Xueying Zheng, Gabriele Ponti, Michael Freyberg +13

By June of 2020, the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) on board the Spectrum Roentgen Gamma observatory had completed its first of the planned eigh…

The warm-hot circumgalactic medium of the Milky Way as seen by eROSITA

N. Locatelli, G. Ponti, X. Zheng +7

The first all-sky maps of the diffuse emission of high ionization lines observed in X-rays by SRG/eROSITA, provide an excellent probe for the study of the warm-hot phase (T~10^6 K)…

SRG/eROSITA X-ray shadowing study of giant molecular clouds

Michael C. H. Yeung, Michael J. Freyberg, Gabriele Ponti +3

SRG/eROSITA is situated in a halo orbit around L2 where the highly variable solar wind charge exchange (SWCX) emission from Earth's magnetosheath is expected to be negligible. The…

The eROSITA Final Equatorial-Depth Survey (eFEDS): Presenting The Demographics of X-ray Emission From Normal Galaxies

N. Vulic, A. E. Hornschemeier, F. Haberl +17

The Final Equatorial Depth Survey (eFEDS), completed during the calibration and performance verification phase of the instrument on $\it{Spectrum\, Ro…
