Continuing on the thread from Friday’s post, I also attended the recent SPIE meeting. Here are my thoughts, as someone who is on the science side of the field, on the engineering and instrumentation conference.
Radio observations of the diffracted shadow cast by an asteroid can be used to nail down its location and determine its size and shape.
The first stellar intensity interferometry experiment in decades!
ALMA has taken a brand-new image of Fomalhaut’s famous debris disk. What can we learn from it?
Today we try to get a sense of what near-in and hot dust disks are like around other stars. Aside from being interesting in its own right, the nature of ‘exozodis’ will offer more clarity for planning exoplanet direct-imaging missions.
Now that gravitational waves have been directly detected, we can begin to use binary black hole mergers to probe strange consequences of strong-field general relativity. Today’s post examines the prospect of detecting an effect called gravitational-wave memory, and considers its potential for helping you get in shape for summer.
