Un'esplosione cosmica con la forza di un miliardo di soli è passata inosservata, finché non ne abbiamo colto l'eco

#ASKAP @astronomia

Alcune delle esplosioni più estreme dell’universo non lasciano quasi alcuna traccia visibile. L’esplosione iniziale non viene osservata, ma le nostre osservazioni possono catturare l’eco di lunga durata che essa lascia quando l’onda d’urto si propaga nell’ambiente circostante.

Your on a Good Thing [TM] when the first trial you run yields "too much" [1] good data :)

SKA -side effects 101

**Cosmic Fast Bursts**

January 28, 2025

The first trial of an Australian-developed technology has detected mysterious objects by sifting through signals from space like sand on a beach.

“That’s the equivalent of sifting through a whole beach of sand to look for a single five-cent coin every minute,”

“We’re also detecting long-period transients, which remain mysterious objects within our galaxy. Both fast radio bursts and these transients were first discovered in Australia, so it is great that we’re continuing the path of discovery with this impressive technology,” Dr Wang said.

Astronomen vinden de langzaamst draaiende radiostraling uitzendende neutronenster

Neutronensterren draaien typisch op zeer hoge snelheden rond. Ze doen dat in enkele seconden of slechts een fractie van een seconde. Astronomen hebben er nu eentje gevonden die anders is, ASKAP J1935+2148 zendt radiosignalen uit met een interval

Are astronomers on the brink of discovering a new celestial object?

Recently, astronomers have been discovering an emerging population of astrophysical objects that resemble neutron stars, but with longer rotation periods. This unique population is challenging our understanding of how these objects form and how they emit radiation.

I got to speak with this exciting new paper’s lead author, Dr Manisha Caleb from The University of Sydney, about this remarkable discovery, which was first found by CSIRO's #ASKAP telescope located in WA.

What if we are on the precipice of something big here? These are def. very exciting times for geeks like me!

Looking at eclipses with radio telescope also gives us insightful info into the active regions of the Sun (like sunspots) as well as helping study background sources twinkling in the Solar wind.

SUPER NEAT NEW SCIENCE!

An enormous ribbon of hydrogen encircling a spiral galaxy called NGC 4632, found with the help of CSIRO's ASKAP radio telescope (also NGC 6156)

📡📡📡

It's a 'polar ring galaxy' - where the gas is inclined almost perpendicular to the galaxy's rotation. Likely an old companion galaxy.

This map ⤵️ shows what elements of the cosmic web are intercepted by the survey beam in the Norma field: voids, clusters of galaxies, thin filaments, massive walls such as the South Pole Wall.
