Tracing Huge, Distant Structures in the Universe
Space is filled with structures that we can’t see directly. How do astronomers trace the underlying dark-matter distribution of the universe?
Astrobites reports on tests of cosmological models using measurements of nearly 2,000 supernovae from the Dark Energy Survey and other sources.
The collapse of a magnetar into a black hole may power the strongest shocks in the universe and produce brief, bright flashes of gamma rays.

A data-driven approach identifies stars with interesting infrared emission without relying on computationally expensive modeling.
Astrobites reports on an analysis of the orbital architecture of JWST’s first directly imaged exoplanet using time-series photometry data from the Transiting Exoplanet Survey Satellite.
Nineteen nearby spiral galaxies surveyed by JWST are presented in one grand ensemble along with a customized image-processing pipeline.
While Type Ia supernovae have been used to determine cosmological distances and study the expansion of the universe, their origins are still under investigation. Recent simulations point to a double-detonation scenario being the catalyst for some of these extremely energetic events.
New observations show that Gliese 229 B is two brown dwarfs rather than one, resolving the mismatch between its measured mass and predictions of evolutionary models.
