4U 1556-60 as a very faint neutron star X-ray binary at 700 pc with an undetected radio jet
Eliot C. Pattie, Thomas J. Maccarone, Thomas Russell +3
4U 1556-60 is a low-mass X-ray binary that was discovered more than 50 years ago as a persistent X-ray source; however, very little was known about it. Recently, Gaia obtained a pa…
A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
Decoding Cygnus X-2: The Critical Role of Reflection in IXPE Data
Honghui Liu, Jiachen Jiang, Adam Ingram +10
We present a spectro-polarimetric re-analysis of the first IXPE observation of Cygnus X-2 which we determine to be mainly in the normal branch, from quasi-simultaneous observations…
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…
The very faint X-ray transient Swift J174610-290018 at the Galactic center
Giovanni Stel, Gabriele Ponti, Nathalie Degenaar +17
Very Faint X-ray Transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (L_X< 1e36 erg s^-1) much lower than typical…
An XMM long look at the accretion disk plasma in the dipping neutron star LMXB 4U1624-490
Eleonora Caruso, Elisa Costantini, Nathalie Degenaar +1
Dipping neutron star low-mass X-ray binaries (NS LMXBs) are systems that exhibit periodic drops in their X-ray light curves. These are believed to be caused by material at the impa…
