... it was of obvious necessity to learn, as early as possible, the exact orbit of the comet upon its return. Following the recovery 5 m Palomar observations, teams of astronomers at the Kitt Peak 4 m and the Canada-FranceHawaii 3.5 m telescopes were immediately successful in detecting P/Halley. At ESO, ...

We think that maybe astronomy has neglected g (2) for longer than was strictly necessary from a technological point of view. It is always eas ...

Deeper Knowledge Through Confusion
... • S ~ 1 Jy surveys at 1.4 GHz can constrain the evolution of the SFRD to z ~ 1.5 • Current surveys disagree below S ~ 100 Jy • EVLA confusion surveys could yield source counts to S ~ 1 Jy at 1.4 GHz and measure the effective spectral index at this level. • EVLA confusion surveys will be the deepe ...

Low radioderived star formation rates in z < 0.5 gammaray burst host
... and radio frequency interference carefully flagged on a channel-bychannel basis. Each frequency band had 2048 1-MHz-wide spectral channels allowing interference to be restricted to a few distinct channels. This was particularly important at 3 cm where powerful interference spikes occurred frequently ...

In contrast, it is increasingly clear that mergers of gas-rich disks cannot be the main formation route of more m ...

Unit 7: Manipulating Light
... Light has fascinated humans for thousands of years. In ancient times, summer solstice was a celebrated event. Even to this day, the midsummer solstice is considered one of the most important events of the year, particularly in the northern-most countries where the contrast between the amount of ligh ...

L25 A NEW CULPRIT IN THE SECOND
... We added to the images 1500 false stars (100 stars at a time) drawn from an isochrone corresponding to the oldest population in Scl and a Salpeter-like IMF. The region labeled “Old” in Figure 2a samples a portion of this isochrone. We then compared the number of false spur stars to the number of fal ...
