Gamma-ray polarisation sharpens multi-messenger astrophysics

The 2020s should see the start of a new type of astrophysics, reports Merlin Kole.

AMS detector given a new lease of life

With its new cooling system in place, the Alpha Magnetic Spectrometer continues its quest to understand the origin of cosmic rays.

Success in scientific management

Barry Barish speaks to the Courier about his role in turning LIGO into a Nobel Prize-winning machine.

Cosmology and the quantum vacuum

The sixth conference in the series marked Spanish theorist Emilio Elizalde’s 70th birthday.

Scoping out the Einstein Telescope

Activities are gathering pace at two sites in Europe where the Einstein Telescope, a proposed next-generation gravitational-wave observatory, may be built.

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is one of several radio telescopes scouring the sky for fast radio bursts.

Renewed doubt cast on origin of fast radio bursts

Researchers trace second repeating fast radio burst to ordinary galaxy, suggesting that extreme environments are not required.

Astroparticle physicists head down under

Wide-ranging discussions at TeVPA featured the DAMA signal, GeV gamma rays from the galactic centre, the 21 cm radio line, AMS's positron excess and a host of cosmic messengers.

Crisis for cosmology?

A new fit to Planck’s 2018 data release exchanges an anomalously large lensing amplitude for a higher energy density, thereby inferring a closed universe.
