A team led by Andrea Botteon used Chandra and eROSITA X-rays to trace the radio 'Treble Clef' to a black hole outburst and a cluster collision. The authors call the two-stage origin likely; the merger evidence comes from the shape of the cluster's hot gas.

Astronomers tie a 10-minute X-ray flash seen by Einstein Probe to merging neutron stars
Astronomers attribute EP250704a, a half-second gamma-ray burst followed by 10 minutes of X-rays, to two neutron stars colliding. The event gives them a test case for the hundreds of X-ray flashes Einstein Probe has logged since its 2024 launch, some of them still unexplained.

Einstein Probe catches ten minutes of soft X-rays after a sub-second gamma-ray burst
Einstein Probe recorded nearly ten minutes of soft X-rays after a short gamma-ray burst whose flash lasted under half a second. By the team's estimate the tail was too soft for gamma-ray instruments to register, so earlier missions would have logged only the flash.

Einstein Probe tracked soft X-rays for nearly 10 minutes after a 0.4-second gamma-ray burst
Einstein Probe saw a likely neutron star merger shine in soft X-rays for nearly 10 minutes after a 0.4-second gamma-ray burst. Its team argues gamma-ray detectors alone may have missed this phase in earlier mergers, a case that so far rests on one event.

Astronomers untangle three overlapping X-ray sources to map the supernova remnant nearest Sgr A*
Mayura Balakrishnan and colleagues separated three overlapping X-ray sources in Chandra data to make the first uncontaminated maps of Sgr A East. The cleaner signal gives a baseline for testing whether the remnant has heated the gas around the Milky Way's central black hole.

XRISM catches a hypergiant's wind plume falling onto the pulsar GX 301-2
XRISM spectra show wind plasma from the hypergiant Wray 977 falling onto the pulsar GX 301-2 during an X-ray flare, a first for any compact object. The spectra back a cause astronomers had long inferred from orbital timing, though so far they cover a single observing window.

The 84 detections came out of public Chandra data on six galaxies with no new observing time, and the class is defined by a spectral shape that co-author Jimmy Irwin thinks may cover three different kinds of stellar remnant.

XRISM clocks wind plasma falling onto the BP Crucis pulsar at 150 kilometres a second
A 16-hour look at the binary caught iron absorption lines sitting below their laboratory energies, and the team takes that shift as gas already on its way onto the neutron star. Rahin says nothing comparable is in the literature.

eROSITA's second release logs 1.9 million X-ray point sources from three stacked sky scans
Three stacked passes over the whole sky produced the largest public X-ray source catalog to date. Most of what it found lies outside the Milky Way, and the consortium says X-ray detection is only the first step.

Chandra spends 634,000 seconds on one quasar and finds a cluster's hot gas already there
A 21-million-Kelvin halo at redshift 3.25 already holds a mature cluster's share of normal matter, before the epoch when such gas was expected to start warming.
