X-ray data trace the radio 'Treble Clef' to a black hole outburst and a later cluster merger

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.

ALMA maps the final flare-up of a dying star in the preplanetary nebula IRAS 06530

Raghvendra Sahai's team used ALMA to find a ring of radius about 16,950 Earth-sun distances around the preplanetary nebula IRAS 06530. The team says it records the star's last flare-up, but the spectra show no gas faster than 16.5 km/s, below the fast outflows a binary-jet origin should produce.

Most distant fast radio burst yet comes from a dwarf galaxy 1,000 times less massive than expected

Astronomers led by Manisha Caleb report FRB 20240304B, the most distant fast radio burst yet, emitted about 3 billion years after the Big Bang. Its host is a dwarf galaxy 1,000 times less massive than expected, and the team favors a magnetar as the source.

CHIME picks out a 9-billion-year-old hydrogen glow using only its own radio data

Canada's CHIME telescope has detected the faint radio glow of hydrogen from about 9 billion years ago using only its own observations. The University of British Columbia says that opens a cheaper path to studying dark energy, once the hydrogen maps are turned into a history of cosmic expansion.

MeerKAT and Webb trace the most distant fast radio burst to a small galaxy at redshift 2.15

MeerKAT and JWST traced fast radio burst FRB 20240304B to a galaxy seen 3 billion years after the Big Bang, more than doubling the distance record. The small, star-forming host is one data point for young magnetars as the source of at least some of these flashes.

ALMA's COMPASS survey detects methanol masers around more than half of 11 infant sun-like stars

ALMA's COMPASS survey found methanol masers around more than half of the 11 infant sun-like stars it studied. The survey puts organic chemistry around stars that are still forming, though its first papers do not trace any of it into a planet.

MeerKAT pins repeating radio bursts to the giant planet Beta Pictoris b

The team used distant quasars as fixed reference points to separate the planet's signal from its star's, then read a magnetic field of at least 1,250 gauss off the emission. The preprint has not been peer reviewed.

CHIME detects the 21 cm hydrogen signal from its own data alone for the first time

CHIME, a Canadian radio telescope, detected the 21 cm glow of distant hydrogen in 94 nights of its own data, without checking against any other telescope. The team sees a cheaper route to studying dark energy, though so far the paper establishes only that the signal is real.

CHIME picks out distant hydrogen's radio glow from 94 nights of its own data

CHIME, a Canadian radio telescope, detected the faint glow of hydrogen from a universe about 5 billion years old using 94 nights of its own data. Any test of dark energy theories comes later, from years of archived observations still to be analysed.

Hotspot ages rising with distance point to four jet outbursts from one black hole

Astronomers led by IISER Pune's Pavan Vijay Khadekar report four pairs of radio hotspots, aged 4.5 to 20.5 million years, around one elliptical galaxy. Their preprint makes the case for the first known quadruple-double radio galaxy, a dated record of one black hole's restarts that wider surveys would need to turn into a rate.

A 21-centimetre stack of 2.5 million galaxies exonerates the cosmic gas supply

Star formation has fallen to under half its rate of 4.5 billion years ago, but a FAST and DESI measurement finds the atomic hydrogen reservoir down only about a third, which moves the bottleneck downstream.

SKA-Low prototype confirms its sunflower antenna layout loses sensitivity at 125 MHz

SKA Observatory engineers found a sensitivity dip at 125 MHz on the 256-antenna AAVS3 prototype and ruled its sunflower layout out of the final telescope. The modified spiral that replaces it drops the repeating 2.4-meter spacings and has so far been checked only in simulation.

ALMA images a planet five times Jupiter's mass interacting with the gas it formed in

MPIA astronomers used ALMA to image WISPIT 2b, a gas giant five times Jupiter's mass, interacting with the gas it formed in. Formation models have rested on simulations and indirect evidence, so a planet still feeding on its birth gas gives them a direct check.

NASA pairs two Landsat scenes with a rainfall summary to show the Murchison in bloom

Above-average June rain and a very wet August in Western Australia's Murchison brought carpets of wildflowers that Landsat 8 caught in late August, in a before-and-after pair where the ground is greener and the flowers themselves go uncounted.

Ten tidal disruption events pin black hole jet launching to 2% of the Eddington limit

Andrew Mummery and Adelle Goodwin report that late radio jets in ten star-shredding events switched on as the feeding rate fell to about 2% of the Eddington limit, the threshold already known from Milky Way black holes.

Jets switch on at 2% of the Eddington limit whether the black hole weighs 10 suns or a million

Adelle Goodwin and Andrew Mummery modelled ten stars torn apart by supermassive black holes and found the late radio jets turning on at the same accretion threshold already known from much smaller black holes in our galaxy.

Fifteen years of Parkes timing turned up three glitches in a pulsar filed as quiet

PSR J1637-4642 spent about nine years of its archival record doing nothing unusual, then jumped its spin rate by 2.7 parts per million in 2018 and twice more since. That says something about baselines as well as neutron stars.

A FAST survey of 55 galaxies turns up two starless hydrogen clouds near M51

Each cloud holds about 3 million solar masses of hydrogen inside a halo of 3.7 billion, the gas fraction cold dark matter models predict for a halo that never made a star, and also what a tidal tail could imitate.

Astrochemistry's next step is checking whether finer molecular maps agree with the old ones

Higher-resolution mapping turns star-forming clouds into comparisons rather than catalogues, but first someone has to check that the finer maps agree with the ones built over previous decades.
