Second Repeating Fast Radio Burst Detected

The globally distributed dishes of the European VLBI Network are linked with each other and the 305-m William E. Gordon Telescope at the Arecibo Observatory in Puerto Rico. Together they have localized FRB121102’s exact position within its host galaxy. Image credit: Danielle Futselaar, www.artsource.nl.

Astrophysicists from the CHIME (Canadian Hydrogen Intensity Mapping Experiment) Collaboration have spotted 13 new fast radio bursts (FRB) — powerful radio flashes probably arriving from far outside the Milky Way, with mysterious origins that continue to be a matter of debate. One of the newly-detected events is the second known example of a repeating FRB. Fast radio bursts are mysterious and rarely detected bursts of energy from space. Image...

Star formation in dwarf galaxies can slowly ‘heat up’ the dark matter, pushing it outwards. The left image shows the hydrogen gas density of a simulated dwarf galaxy, viewed from above. The right image shows the same for a real dwarf galaxy, IC 1613. In the simulation, repeated gas inflow and outflow causes the gravitational field strength at the center of the dwarf to fluctuate. The dark matter responds to this by migrating out from the center of the galaxy, an effect known as ‘dark matter heating.’ Image credit: Read et al, doi: 10.1093/mnras/sty3404.

This image from the NASA/ESA Hubble Space Telescope shows the reflection nebula NGC 1333 and associated Herbig-Haro objects. The picture was snapped by Hubble’s Advanced Camera for Surveys (ACS). The image was made through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / K. Stapelfeldt.

The galaxy cluster Abell S1063 was observed by the NASA/ESA Hubble Space Telescope as part of the Frontier Fields Program. The huge mass of the cluster -- containing both baryonic matter and dark matter -- acts as cosmic magnification glass and deforms objects behind it. In the past astronomers used this gravitational lensing effect to calculate the distribution of dark matter in galaxy clusters. A more accurate and faster way, however, is to study the intracluster light (visible in blue), which follows the distribution of dark matter. Image credit: NASA / ESA / M. Montes, University of New South Wales.
