  • What do you know about WMAP?
  • What spacecraft have gone up recently?
  • What's the latest, coolest instrumentation?
  • what do you know about HST?
  • why do we build large telescopes on the ground, if HST has a much better resolution with just 2.3m?
  • If we observed a neutron star in LMC from a X-ray telescope, are we able to use a optical telescope to find out if it has a optical companion?
    • How many stars in LMC?
    • What's the angular resolution for a X-ray telescope (some early X-ray telescope before Chandra)?
    • What's the angular resolution for a typical optical telescope?
    • In the field we observed the neutron star, how many stars we would observed in optical?

  • What's the typical spectral resolution for a optical telescope?
  • What distances can we get to using parallax measurements?

  • What is the difference between atmospheric effects in optical and radio astronomy? (RS)
  • How was the frequency band of MWA chosen? (I'm in MWA; other experimentalists could get an analogous question). (RS)
