Old Galactic novae in the eROSITA All Sky Survey
Gloria Sala, Frank Haberl, Axel Schwope +4
Nova explosions occur on accreting white dwarfs. A thermonuclear runaway in the H-rich accreted envelope causes its ejection without destroying the white dwarf, and an increase in…
Significant reflection and absorption effects in the X-ray emission of the Intermediate Polar IGR J17195-4100
Elif Şafak, Şölen Balman, Gloria Sala
X-ray emission is from shock-heated plasma in magnetic cataclysmic variables, and is processed by absorption and scattering before reaching the observer. We investigate these effec…
Gamma-ray observations of MAXI J1820+070 during the 2018 outburst
H. Abe, S. Abe, V. A. Acciari +439
MAXI J1820+070 is a low-mass X-ray binary with a black hole as a compact object. This binary underwent an exceptionally bright X-ray outburst from March to October 2018, showing ev…
The supersoft X-ray source in V5116 Sgr I. The high resolution spectra
G. Sala, J. U. Ness, M. Hernanz +1
Classical novae occur on the surface of an accreting white dwarf in a binary system. After ejection of a fraction of the envelope and when the expanding shell becomes optically thi…
Supersoft X-rays reveal a classical nova in the M 31 globular cluster Bol 126
M. Henze, W. Pietsch, F. Haberl +17
[Abridged] Classical novae (CNe) represent the main class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. Only three confirmed novae and th…
M31N 2008-05d: A M 31 disk nova with a dipping supersoft X-ray light curve
M. Henze, W. Pietsch, F. Haberl +4
Classical novae (CNe) represent a major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. Significantly different SSS properties of CNe…
Constraints on the mass and radius of the accreting neutron star in the Rapid Burster
Gloria Sala, Frank Haberl, Jordi Jose +4
The Rapid Burster (MXB 1730-335) is a unique object, showing both type I and type II X-ray bursts. A type I burst of the Rapid Burster was observed with Swift/XRT on 2009 March 5,…
CXOM31 J004253.1+411422: The first ultra-luminous X-ray transient in M 31
A. Kaur, M. Henze, F. Haberl +6
We seek clarification of the nature of X-ray sources detected in M 31. Here we focus on CXOM31 J004253.1+411422, the brightness of which suggests that it belongs to the class of ul…
The deep XMM-Newton Survey of M 31
H. Stiele, W. Pietsch, F. Haberl +5
Aims. M 31 has been completely imaged for the first time obtaining a luminosity lower limit ~10^35 erg s-1 in the 0.2-4.5 keV band. Our XMM-Newton EPIC survey combines archival obs…
Nova M31N 2007-12b: Supersoft X-rays reveal an intermediate polar?
W. Pietsch, M. Henze, F. Haberl +4
For the He/N nova M31N 2007-12b, we analyzed XMM-Newton EPIC and Chandra HRC-I observations of our monitoring program performed at intervals of ten days and added results of a XMM-…
XMM-Newton X-ray and UV observations of the fast nova V2491 Cyg during the supersoft source phase
J. -U. Ness, J. P. Osborne, A. Dobrotka +12
Two XMM observations of the fast classical nova V2491Cyg were carried out on days 39.93 and 49.62 after discovery, during the supersoft source (SSS) phase, yielding simultaneous X-…
X-ray monitoring of classical novae in the central region of M 31. II. Autumn and winter 2007/2008 and 2008/2009
M. Henze, W. Pietsch, F. Haberl +7
[Abridged] Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. We performed a dedicated monitor…

M. Henze, W. Pietsch, F. Haberl +9
(Abridged) Classical novae (CNe) have recently been reported to represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbour galaxy M 31. We c…
Recent discoveries of supersoft X-ray sources in M 31
M. Henze, W. Pietsch, F. Haberl +9
Classical novae (CNe) have recently been reported to represent the major class of supersoft X-ray sources (SSSs) in the central area of our neighbouring galaxy M 31. This paper pre…
X-ray observations of classical novae. Theoretical implications
M. Hernanz, G. Sala
Detection of X-rays from classical novae, both in outburst and post-outburst, provides unique and crucial information about the explosion mechanism. Soft X-rays reveal the hot whit…
