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)
- What are the following and to what sorts (read: wavelengths) of astronomers care about them? (RS)
- Adaptive Optics
- How does complexity of the AO system scale with aperture size?
- What is the characteristic size of turbulent cells?
- Closure phase
- What are measurements int he UV plane called?
- Bolometer
- CCD
- How do X-ray and optical astronomers use CCDs differently?
- Grazing incidence optics?
- Downmixing
- Adaptive Optics
