I'd like to announce the availability of version 1.0 of PyImfit [https://github.com/perwin/pyimfit], a Python wrapper around the (very) fast, flexible, C++-based galaxy image-fitting program Imfit [https://github.com/perwin/imfit]. 🔭 (1/7)

New paper! (in press at MNRAS)
I present a study of barred spiral galaxies in the local universe aimed at finding out how many have inner bars (making them double-barred) and how many have nuclear rings. (1/7) 🔭🧪

Using a volume- and mass-limited (D < 30 Mpc, log (M_star/M_sun) $\geq 9.75$) sample of 155 barred S0-Sd galaxies, I determine the fraction with secondary structures within their bars. Some 20 +/-...
