The SRG/eROSITA All-Sky Survey DR2: Cumulative X-ray catalogues from the first three surveys and multi-wavelength counterparts in the western Galactic hemisphere
M. E. Ramos-Ceja, G. Lamer, M. Salvato +111
The eROSITA telescope array on board the Spektrum-Roentgen-Gamma (SRG) mission began its all-sky survey program in December 2019, scanning the sky at an approximately six-month cad…
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…
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…
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…
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…
Disentangling the Galactic centre X-ray reflection signal using XMM-Newton data
K. Anastasopoulou, I. Khabibullin, E. Churazov +5
We investigate the X-ray emission from the Galactic Centre (GC) region, focusing on the 6.4 keV fluorescent line of neutral or weakly ionised iron, which is commonly attributed to…
Hunting for High-Mass X-ray Binaries in the Galactic Center with NuSTAR
Shifra Mandel, Julian Gerber, Kaya Mori +9
The central deg region of our Galaxy contains X-ray point sources that were detected by a series of Chandra observations over the last two decades. Ho…
eROSITA X-ray Analysis of the PeVatron Candidate Westerlund 1
Konstantin Haubner, Manami Sasaki, Alison Mitchell +7
It is unclear which fraction of cosmic rays above an energy of 1 PeV is accelerated by the observed Galactic PeVatron population. These sources' gamma-ray data is typically degener…
An acceleration-radiation model for nonthermal flares from Sgr A
Maria Petropoulou, Gabriele Ponti, Giovanni Stel +1
(Abridged) Sgr A is the electromagnetic counterpart of the accreting supermassive black hole in the Galactic center. Its emission is variable in the near-infrared (NIR) and…
XMM-Newton and NuSTAR discovery of a likely IP candidate XMMU J173029.8-330920 in the Galactic Disk
Samaresh Mondal, Gabriele Ponti, Luke Filor +7
We aim at characterizing the population of low-luminosity X-ray sources in the Galactic plane by studying their X-ray spectra and periodic signals in the light curves. We are perfo…
The SRG/eROSITA all-sky survey. X-ray emission from the warm-hot phase gas in long cosmic filaments
X. Zhang, E. Bulbul, N. Malavasi +24
The properties of the warm-hot intergalactic medium (WHIM) in cosmic filaments are among the least quantified units in modern astrophysics. The Spectrum Roentgen Gamma/eROSITA All…
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…
Characterisation of the X-ray point source variability in the eROSITA south ecliptic pole field
David Bogensberger, Kirpal Nandra, Mara Salvato +11
Aims: During the Spectrum Roentgen Gamma (SRG)/ eROSITA all-sky surveys, X-ray sources close to the South Ecliptic Pole (SEP) are observed almost every 4 hours. We aim to identify…
The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere
