ASASSN-13co: A Type-Defying Supernova

There are arguably a lot of things defy categorization, but it’s not everyday that we find something that suggests we do away with our categories altogether. The authors of today’s paper believe that the recently-discovered Type II supernova ASASSN-13co — read that as “assassin”, please — might just be one of the latter.

How do satellite galaxies orbit their host?

Satellite galaxies orbiting a host galaxy seem to display highly anisotropic angular distributions.

Tuning in to Radio Exoplanets

Title: Limits on low frequency radio emission from southern exoplanets Authors: Tara Murphy, et al. First Author Institution: Sydney Institute for Astronomy, The University of Sydney, Australia Status: Accepted for publication in MNRAS Astrobites is no stranger to exotic exoplanet discoveries- the Kepler mission alone has increased our knowledge of these worlds by leaps and bounds, and many exciting discoveries have been done […]

Dust gets interesting

Thought dust could only bore you? Think again: it may obscure our view of time’s very beginning!

Searching for Galaxy Clusters with the SZ Effect

The Sunyaev-Zeldovich effect is a unique way of searching for galaxy clusters that complements multi-wavelength imaging efforts.

The first discovery of a Thorne–Żytkow Object?

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.

Gamma rays: a window to the first stars?

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.

Can gamma ray bursts be used as standard candles?

Some GRB-SNe pairs show interesting correlations across their light curves.

Piecing together the Hubble constant

Different methods of measuring the Hubble constant yield slightly different values, but they are still in reasonable agreement.

A new method for cosmic distances: using active galactic nuclei

Time delays in the light from AGNs’ dusty torii can tell us the intrinsic luminosity and hence the distance to the AGN.
