New Frontiers in CCD Systematics
CCDs have been the workhorse of astronomy since the 1970s, but today’s paper shows that we’re still learning about ways they can systematically affect the results of our data.
Turning a Blind Eye: Fighting the Gender Gap in Telescope Proposal Success
If you’re a woman in STEM, you’re probably all-too-familiar with the biases you might face in your field. Today’s paper examines the biases evident in telescope time awarded to men vs. women.
Choosing targets with TESS
With the launch of TESS, we will soon have many more exoplanet candidates. But how do we determine which are the most valuable for follow-up observations?
A classic optics experiment, in space with asteroids and AGNs!
Radio observations of the diffracted shadow cast by an asteroid can be used to nail down its location and determine its size and shape.
Optics to outrace them all
Astronomers are using a once-secret technology to scrutinize Kepler stars. Are rocky planets headed for a takedown?
Probing the source of a mysterious (dark matter?) line in the laboratory
A laboratory astrophysics experiment calls into question the proposed dark matter origin of an unidentified spectral line at 3.5 keV
