Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…
Fast optical spectroscopic observations of PSR J1023+0038 over one orbital period
M. M. Messa, M. C. Baglio, P. D'Avanzo +8
The paper presents minute‑resolution optical spectroscopy of the transitional millisecond pulsar PSR J1023+0038 over a full orbit, revealing rapid changes in emission‑line properti…
A FAST search for radio pulsations during the dormant state of the AMSPs IGR J00291+5934 and MAXI J1957+032
A. Marino, E. Parent, F. Coti Zelati +15
Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries which can evolve into "recycled" radio millisecond pulsa…
On The Nature of Einstein Probe Transient EP250916a: Insights from X-ray, Optical, and Radio Observations
Gaurava K. Jaisawal, Giulia Illiano, Francesco Carotenuto +7
We report multi-wavelength studies of the transient EP250916a, detected by the Einstein Probe on 2025 September 16. Located at low Galactic latitude, the source exhibited a rapid X…
Multi-wavelength outburst activity from EP J174942.2-384834: a very faint X-ray transient discovered by Einstein Probe
F. Coti Zelati, A. Marino, Y. L. Wang +27
We report the discovery and multi-wavelength characterization of the Galactic transient EP J174942.2384834, first detected by the Einstein Probe during a faint X-ray outburst in…
Einstein Probe discovery of EP J171159.4-333253: an eclipsing neutron star low-mass X-ray binary with clocked bursts
Y. L. Wang, F. Coti Zelati, E. Parent +27
EP J171159.4-333253 is a new neutron-star low-mass X-ray binary discovered in outburst by the Einstein Probe (EP) on 2025 June 23, exhibiting clocked type-I X-ray bursts, eclipses…
