  • This paper reports the discovery of a water maser at redshift 2.64 in the dust- and gas-rich gravitationally lensed type-1 quasar MG J0414+0534. Using the locally determined luminosity function, the probability of finding a maser this luminous associated with any single active galaxy is 10−6, leading to the conclusion that the volume densities and luminosities of masers are higher at that epoch.

  • The precise location of megamaser emission regions in galactic accretion disks has been challenging to pinpoint. Now with interferometric observations leveraging baselines larger than the Earth’s diameter, the missing information is getting closer and closer.

  • The climate crisis is no longer a prediction for the future, it is happening here and now. Astronomers have realized that they need to become part of the solution and are working towards reducing their own carbon footprint as well as communicating an astronomical perspective.
