A soft-spectrum PULX candidate is reported in Cen A but XMM-SAS randomisation during data reduction renders the marginal 1.27 Hz pulsation detection unreliable across repeated reductions.

First IXPE polarization measurement of GX 340+0 in normal branch yields PD 1.22±0.25% and PA 38±6°, consistent with origin in blackbody or Comptonized emission, with radio flux lower than in horizontal branch.
Discovery of Spearman correlation 0.8 between energy-dependent time lag and polarization degree in Swift J1727.8-1613, with theoretical arguments for additional mechanisms beyond inverse Comptonization.
EP J174942.2-384834 is classified as a very faint X-ray transient black hole candidate based on its hard X-ray spectra, optical/UV brightening correlated with X-rays, and lack of radio emission.
New XRISM observations confirm a highly broadened, pulsating Fe K line from the accretion column of Hercules X-1 that varies with pulse phase and evolves with the 35-day precession cycle.
New EP-FXT data on the 2024 outburst of magnetar 1E 1841-045 shows energy-dependent multi-peaked pulses, spectral hardening, BB temperature-pulse intensity correlations, and effective separation from supernova remnant emission.
An MCMC-based period search method recovers previously reported candidate periods in FRB 20201124A observations.
Wideband observations show M28A giant pulses differ from FRB 20200120E bursts in duration, luminosity, timing statistics, and spectral structure, yielding no strong evidence for a direct link.
The paper reports on the Astropy v5.0 release, project updates, ecosystem connections, and challenges facing the community-oriented open-source astronomy software effort.

Significant or Not? The Impact of Randomisation During Data Reduction on Confirming a New Pulsating Ultraluminous X-ray Source Candidate in Centaurus A
A soft-spectrum PULX candidate is reported in Cen A but XMM-SAS randomisation during data reduction renders the marginal 1.27 Hz pulsation detection unreliable across repeated reductions.

X-ray and Radio Campaign of the Z-source GX 340+0 II: the X-ray polarization in the normal branch
First IXPE polarization measurement of GX 340+0 in normal branch yields PD 1.22±0.25% and PA 38±6°, consistent with origin in blackbody or Comptonized emission, with radio flux lower than in horizontal branch.
