Abstract
I present the results of a systematic search for classical novae in the Galactic bulge and Magellanic Clouds in data from the OGLE survey. I measured nova rates in all those environments: 13.8 +/- 2.6 per yr(Milky Way bulge), 2.4 +/- 0.8 per yr (LMC), and 0.9 +/- 0.4 per yr (SMC). The K-band luminosity-specific nova rate in the Galactic bulge is significantly higher than in other galaxies, suggesting different nova rates per unit mass in different Galactic populations. I also provide strong upper limits on the number of very frequently erupting recurrent novae, which indicates they cannot be a significant channel of SN Ia progenitors. Finally, I identified several post-nova candidates based on their photometric variability.
