  1. 📡 Beyond citizen science: engineers building the SKA-Low radio telescope in Australia had to rework its antenna layout. The original sunflower-inspired Vogel spiral placed antennas a regular 2.4 m apart, causing destructive interference - a blind spot - at 125 MHz whenever the array looked toward the Milky Way. The fix: a "Perturbed Vogel" pattern.

  3. Here's a rendered concept for the observatory site. The small dishes are replicas of the radio telescope currently connected to the network (build details: community.titanobservatory.org). The larger 10m is the one we still need funding to purchase. Each telescope is powered by a solar array and battery, and connected to the utility shed via fiberoptic to prevent long runs of conductors and allow every telescope to be entirely self-sufficient.

  4. 📡 First confirmed radio signal from a single exoplanet! The MeerKAT array caught variable radio bursts from the gas giant Beta Pictoris b (63 light-years away) – an aurora much like Jupiter's. From it, astronomers derived a magnetic field thousands of times stronger than Earth's. Magnetospheres are key to finding habitable worlds.

  8. Here's a recording of the presentation I gave to the Austin Astronomical Society. In it I lay out the observatory's goals, give a tour of the platform, and introduce the newest member of the team, Jon Richards, who will be developing an open-source telescope controller for the observatory and the community!

    'Discovery of Two Consecutive Profile Change Events on PSR J0437-4715'

    I’m so excited to finally share my second PhD paper!

    About a year ago, I discovered something interesting in the closest and brightest millisecond pulsar (MSP) to Earth, PSR J0437-4715.

    It appeared there were not one, but two long-term profile change events occurring one after the other. These events are extremely rare in the MSP population. I reported on another one about a year ago.

    We used to think these objects were stable over the long term and ran our precision timing experiments on them. However, these new findings are now challenging that idea. New studies are emerging showing that many MSPs have variable profiles.

    The exciting thing is that we see only certain parts of the profile affected, along with the polarisations, confirming a magnetospheric origin. What is really fascinating is how similar both events are - it’s like the magnetosphere becomes disrupted but re-organises itself into its original configuration.

    Here’s my feature article in #SpaceAustralia with these exciting findings!

  13. 📡 ESO has signed a contract with France's CNRS to develop a wideband intermediate frequency processor (WIFP) for ALMA. It will digitise the receiver signal from each of the 66 antennas at 40 billion samples per second — ten times today's rate. ESO says the throughput gain is like adding six antennas. Due mid-2028.
