Sadly a DECRA can only purchase up to 1/3rd of a house in Sydney, let alone a giant radio telescope…

Or just refurbished the one already there!

Does the telescope actually come with the land? And the buyer could (in theory) do whatever they want with the telescope?

Could tell the antennas were all pointed at the same spot and that data was streaming easily enough!

There was indeed a large cat. But only a single antenna…

An institute or grant not budgeting for APCs is apparently a legitimate reason to ask RAS for a fee waiver!
I asked for one during a brief period between MNRAS going gold open access and my institution making a deal with them, and it was granted

And finally, some pulsars live in unusual locations.
Like this millisecond pulsar that I helped find in the central region of our Galaxy! And is embedded in a giant glowing filament of radio light!!

Some neutron stars have extremely powerful magnetic field and do all sorts of whacky things. Like emitting beams fast radio bursts 💥
Or behave in totally unexpected ways: doi.org/10.1093/mnra...
And imprint their magnetic fields on the emitted radio waves: doi.org/10.1038/s415...

The dynamic magnetosphere of Swift J1818.0–1607
ABSTRACT. Radio-loud magnetars display a wide variety of radio-pulse phenomenology seldom seen among the population of rotation-powered pulsars. Spectropol

There’s also a unique “double pulsar” that has provided an extremely powerful tool for testing relativity: www.aanda.org/articles/aa/...

By carefully tracking the rotation rates of 100’s of pulsars, we’ve been able to peer into their insides: doi.org/10.1093/mnra...
And realise that both the rate at which their spins slow down and emit radio waves are A LOT more variable than once thought: doi.org/10.1093/mnra...

The impact of glitches on young pulsar rotational evolution
ABSTRACT. We report on a timing programme of 74 young pulsars that have been observed by the Parkes 64-m radio telescope over the past decade. Using modern

We’ve looked with Murriyang (the 64-m Parkes radio telescope) at 8-9 GHz, and still didn’t see any pulses from the object in the Snake. SKA-Mid should detect or rule out pulsed emission when it comes online in ~3-5 years.
