The SRG/eROSITA diffuse soft X-ray background II. spectra and morphology of the eROSITA bubbles in the western Galactic hemisphere

Michael C. H. Yeung, Martin G. F. Mayer, Andy Strong +15

The eROSITA bubbles (eRObub) were discovered in 2020 in the first SRG/eROSITA All-Sky Survey, and are among the most extended structures in the X-ray sky. Using eROSITA all-sky map…

The average X-ray spectrum of the volume-complete M-, F-, G-, and K-type star sample within 10 pc of the Sun

Xueying Zheng, Gabriele Ponti, Nicola Locatelli +15

F, G, K and M type stars are the most abundant stellar population in the Milky Way and are expected to contribute to its diffuse X-ray emission. Yet their intrinsic average X-ray s…

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…

The hot circumgalactic medium in the eROSITA All-Sky Survey III. Star-forming and quiescent galaxies

Yi Zhang, Johan Comparat, Gabriele Ponti +17

The circumgalactic medium (CGM), as the gas repository for star formation, might contain the answer to the mysterious galaxy quenching and bimodal galaxy population origin. We meas…

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…
