📡 China's FAST radio telescope revealed peculiar behavior of RRAT J1541+4703. This rotating radio transient switches between sporadic bursts and normal pulsar mode. It spends 98% of time in RRAT state; pulsar episodes last just 20–170 pulses. It may represent an evolutionary link from pulsars to RRATs.

FAST observes a peculiar rotating radio transient that also switches to pulsar states

Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), Chinese astronomers have explored the behavior of a rotating radio transient (RRAT) known as RRAT J1574+4703. The new observations found that this object switches between RRAT and normal pulsar states. The finding was detailed in a paper published March 25 on the arXiv pre-print server.

Typisches Aprilwetter: Erst dicht bewölkt und ziemlich unbeständig 🌧️
Doch am Ende hat die Sonne sich noch gezeigt – und wir konnten sogar mit den Teleskopen beobachten 🔭
Dazu gab es einige spannende Stationen und gut gefüllte Vorträge – danke fürs Vorbeikommen!❤️

🔭 Mysterious radio signal with a 36-minute period! Astronomers using ASKAP discovered source ASKAP J1424 – emitting 100% polarized signals of unknown nature. It could be a white dwarf binary system. The signal lasted just 8 days before vanishing.

Astronomers discover long-period radio transient of unknown origin

Using the Australian SKA Pathfinder (ASKAP), astronomers have discovered a new long-period radio transient source, which received the designation ASKAP J142431.2–612611 (ASKAP J1424 for short). The newfound transient has a period of approximately 36 minutes and its nature is unknown. The finding was reported in a paper published March 9 on the arXiv preprint server.

STAR PARTY CHAOS

1 Night at a Star Party… BEST NIGHT EVER

one night. that’s all it took

rocked up to the Messier Star Party thinking it’d be a chill night looking at stars… yeah nah

ended up interviewing Norm about a planispheric astrolabe he literally designed and built, Hugh with his home-built 6" RC, and Phil from the radio astronomy crew about what they’re doing with the dish out at LMDSS

ran Messier Bingo, gave away prizes, pointed telescopes at the Sun, then spent the rest of the night imaging under stupidly good skies

and somewhere in between all that… just hung out with a bunch of legends I haven’t seen in ages

one night, way too much fun, zero regrets

📡 Millisecond pulsars emit radio signals from unexpected places!

A CSIRO & Max Planck study of ~200 pulsars found a third broadcast radio waves from two regions – not just near the surface, but also from a "current sheet" beyond the light cylinder, where magnetic fields whip around at near light speed.

Signals match gamma-ray data from NASA's Fermi telescope.

Radio signals from the edge of extreme stars

A team of German and Australian astronomers found evidence that some of the fastest-spinning stars in the Universe broadcast radio waves from far beyond where scientists thought possible.

Radiosignale aus dem Randbereich extremer Sterne

Ein Team von Astronomen hat festgestellt, dass einige der am schnellsten rotierenden Sterne, die sogenannten Millisekundenpulsare, Radiowellen aus verschiedenen, weit voneinander entfernten Regionen aussenden. Diese Erkenntnis stellt die bisherige Annahme in Frage, dass Radiowellen nur in der Nähe der Sternoberfläche erzeugt werden. Die Entdeckung zeigt, dass die Signale aus Bereichen stammen können, in denen Magnetfelder mit nahezu Lichtgeschwindigkeit rotieren.
