All Those Question Memes

weather: foggy
outside: 8°C
mood: dorky
Because I can't keep up with all the memes, I'll boil it down to:

  1. Tell me something about yourself that I didn't know.

  2. Tell me something you've discovered about me.

  3. Tell me something else. Anything at all, but if you need a writing prompt, I have Astronomy on my mind today.

    1. Easy:

      Look up at the pretty sparklies in the sky. How does it make you feel?

    2. A little more challenging:

      Our neighbor galaxy, Andromeda, has a luminosity (intrinsic brightness) 3 times as bright as the Luminosity of our Milky Way galaxy, LAndromeda = 3LMW, and is at a distance of dAndromeda = 0.7 Mpc. The flux we observe from the Andromeda galaxy (apparent brightness) is 10,000 times brighter than the flux observed from a distant quasar, fAndromeda = 104fquasar. This quasar has a luminosity that is 1000 times the luminosity of our Milky Way galaxy, Lquasar = 103LMW.

      What is the distance d to the quasar? Show your work.

      Solution

      fAndromeda/fquasar = ( LAndromeda/Lquasar ) ( Andromeda/quasar )

      quasar/Andromeda = ( fAndromeda/fquasar ) ( Lquasar/LAndromeda )

      dquasar/dAndromeda = ( fAndromeda/fquasar ) ( Lquasar/LAndromeda )

      dquasar/dAndromeda = (104) ( 103LMW/3LMW )

      dquasar = 107/3 x 0.7 Mpc

      = 1826 x 0.7 Mpc = 1.28 x 10³ Mpc

    3. OH MY GOD WHERE THE HELL WERE YOU BEFORE I GOT MARRIED?!?!:

      Explain how antennas and electromagnetic wave propagation work using the concepts of divergence and curl with mention of their practical applications in Astronomy.
