The Sunyaev-Zeldovich effect is a unique way of searching for galaxy clusters that complements multi-wavelength imaging efforts.
For the first time, astronomers have announced a Thorne–Żytkow Object candidate- a bizarre system in which a neutron star is surrounded by an envelope of stellar material.
The longest-lasting, most energetic explosions in the universe might occur in rare stars very similar to the very first stars to form in the universe.
Some GRB-SNe pairs show interesting correlations across their light curves.
Different methods of measuring the Hubble constant yield slightly different values, but they are still in reasonable agreement.
Time delays in the light from AGNs’ dusty torii can tell us the intrinsic luminosity and hence the distance to the AGN.
From examining extrasolar planetary systems, we can test if the Titius-Bode “law” is actually a law.
How do pulsating stars give away their secret identities as binary dance partners? In this paper, the authors demonstrate a new way to not only detect binaries we may have missed in the Kepler data, but also to measure their velocities without spectra.
Kepler finds the signature of a transiting white dwarf. Instead blocking the light of its companion star, the white dwarf magnifies it, creating a light curve that periodically brightens.
HD 95086 b is one of the first exoplanets directly imaged with the newly commissioned instrument Gemini Planet Imager. This is only the first in what is likely to be a long line of exciting results coming from this state of the art instrument.
