We present estimates for the occurrence rates of hot Jupiters around dwarf stars based on data from Transiting Exoplanet Survey Satellite (TESS) Prime Mission. take 97 orbiting 198,721 AFG (ranging in mass $0.8M_{\odot}$ to $2.3M_{\odot}$) an independent search using TESS Mission data. estimate our planet sample's false positive as $14\pm7\%$ A stars, $16\pm6\%$ F and $0\%$ G stars. find Jupiter $0.29 \pm 0.05\%$ $0.36 0.06\%$ $0.55 0.14\%$ with a weighted average across $0.33\pm0.04\%$.

We present a new 2 Ms Chandra observation of the cluster merger Abell 2146, which hosts two huge M~2 shock fronts each ~500 kpc across. For first time, we resolve and measure width shocks. The best-fit for bow is 17+/-1 upstream 10.7+/-0.3 kpc. A narrow collisionless will appear broader in projection if its smooth shape warped by local gas motions. show that both widths are consistent with shocks blurred motions 290+/-30 km/s. forms later on than therefore expected to be significantly...
