Transient phase space showing radio luminosity versus the product of timescale and observing frequency for different transient source classes, following Cordes et al. (2004).
This is a figure from Murphy & Kaplan (2025) published in PASA. See the paper text (Figure 1 caption) for a full description.

Participation in Australian high school #Physics is declining!
The proportion of Yr 12 students studying physics fell from 14.9% in 2015 to 12.1% in 2023; gender ratio unchanged.
(Luckily this hasn't impacted the number of students studying Physics @sydney.edu.au, but it is a broader issue).

In an era that is very cynical about higher education, it's great to see students from a range of cultural and educational backgrounds working together, sharing their experiences and recommending books to read. Both on campus and online.
