Investigating Early Populations of Galaxies with the Best Telescopes in the Universe
Galaxy clusters act like cosmic telescopes, magnifying our view of the universe. These exceptionally massive structures allow astronomers to gaze deep into the cosmos and study galaxies during early ages of the universe in fantastic detail. With the completion of the Frontier Fields survey, we can now study a population of magnified, distant galaxies like never before.
Disturbed Naps and Black Hole Mass Gaps
LIGO-Virgo open public alerts give you a chance to listen in to the latest discoveries as they happen – in real time! For instance, you can follow astronomers getting closer to figuring out where the dividing line lies between neutron stars and black holes.
Uncovering a Cosmic Matter Reservoir
Uncovering promising evidence that may reveal the location of the missing baryonic matter in the universe.
FRB 121102 CHIMEs in Again
Fast radio bursts, or FRBs, are a newer and somewhat mysterious phenomenon in radio astronomy. This paper details how the authors used a new instrument called CHIME/FRB to observe and put new constraints on FRB 121102, one of the few FRBs known to repeatedly send signals.
It Takes Two to Tango: Eclipsing White Dwarfs Push General Relativity to its Limit
The Zwicky Transient Factory (ZTF) observes the entire northern sky and collects data on as many stars as possible. Combing through the light curves of 20 million stars with periodic changes in brightness, the authors of today’s paper found a hidden gem called ZTF J1539+5027, an eclipsing white dwarf binary with an orbital period of only 6.91 minutes.
Using a Random Forest to Classify ASAS-SN Variable Stars
ASAS-SN searches for supernova and finds variable stars too! They found so many (~90,000) that they decided to classify them all. How do you go about classifying 90,000 things? Machine learning, of course!
