Questions in this category have been asked by PJ,MT

  • 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 photometric precision that can be achieved from the ground? What limits the attainable photometric precision?
  • At optical wavelengths, what's the typical limit to the effective telescope size set by atmospheric seeing? (RS)
  • What is the seeing at Magellan on a good night? (RS)
  • 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)
