Multi-messenger adventures

"This book offers a well-balanced introduction to particle and astroparticle physics, requiring only a basic background of classical and quantum physics."

DESY’s astroparticle aspirations

Christian Stegmann, director of DESY’s newly established research division for astroparticle physics, describes the ambitious plans ahead in this vibrant field.

First images of the centre of a galaxy

On 10 April, researchers working on the Event Horizon Telescope released the first direct image of a black hole.

An optical image of the Cow and its host galaxy

Mysterious burst confounds astrophysicists

Hypotheses are that the Cow was either a compact object being destroyed when coming too close to a black hole, or a special type of supernova in which a black hole or magnetar is produced.

Events such as this, showing the second highest E T miss monojet event recorded in the 2016 ATLAS data, were used to search for signs of dark energy. Credit: ATLAS

Colliders join the hunt for dark energy

The ATLAS collaboration carried out a first collider search for light scalar particles that could contribute to the accelerating expansion of the universe.

Solving the next mystery in astrophysics

Until recently the number of theories on the origin of fast radio bursts outnumbered the number of observations.

Gaia finds evidence of old Milky Way merger

Many of the stars appearing in the night sky did not originate from within our galaxy.

Particle physics meets astrophysics and gravity

The 7th International Conference on New Frontiers in Physics (ICNFP 2018) took place on 4–12 July in Kolymbari, Crete.

Gravitational hunt for extra dimensions

If extra dimensions are large, part of the gravitational field would “leak” into the extra dimensions and gravitational waves would be weaker than expected.
