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.

Webb spectra identified nine new brown dwarfs in the IC 348 nursery, the faintest estimated at about two Jupiter masses, a record low for the class. It is still open whether brown dwarf formation stops there or this survey simply could not see any fainter.

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.

Astronomers scheduled an X-ray observation to land on a predicted outburst of AT 2016blu and saw emission consistent with accretion onto a compact companion. It is the first luminous blue variable reported with such a partner.

The Kyoto-led model says an axion signal should peak in Southeast Asia, but the decade of records came from Britain, and the several unexplained dark photon candidates it also turned up cannot be checked from one station.

If the Universe's first supermassive black holes grew out of stars heated by WIMP dark matter, that history would still sit in a background measured billions of years later. A two-author Letter says the share could be dominant.

The fifth antenna of a project begun in 2009 entered service on Aug 3. It leaves 12 mid-size dishes serving more than 40 spacecraft, with part of that capacity already promised to backup duty.

MoM-BH*-1 shows the deepest Balmer break yet measured, which its discoverers read as a 100,000-solar-mass black hole inside a dense gas cocoon 660 million years after the Big Bang.

A Colgate University pair argue the nanohertz gravitational-wave background may be dominated by descendants of dark-matter-powered stars, which makes the signal an abundance limit on early seeds.
