The Dark Matter

Such a particle does not exist within the standard model of particle physics. Dark matter makes up 25 % of the energy density of the universe. The true nature

The challenge now is to understand the underlying physics of the particles that make up dark matter and the nature of dark energy. The lecture includes

Contribution from the students of the 4th CERN–CLAF School of High-Energy. Physics who participated in the Discussion Session addressing the issues of dark

The notion of “dark matter” emerged from several astronomical observations concerning the structure of galaxies, the rotation of stars and neutral hydrogen gas

13 Mar 2025 Dark matter is an unknown substance that makes up about 80% of the In this colloquium, Jelle Aalbers will discuss the evidence for the

Subject headings: multiverse, universe, photons, protons, dark matter, expansion. 1. INTRODUCTION. The previous arXiv.1101.0161 paper, found dark energy to be

The goal of this book is to make sense of the specters that represent dark matter: to explain how astronomers came to know about it; how theoreticians uncovered

According to theory, when a particle of dark matter collides with its antiparticle, they annihilate, unleashing a burst of energy and exotic particles

In Section 4 we measure the distribution in dark matter halo mass as a function of redshift, luminosity, half-light radius, and colour. In Section 5 we repeat

Dark matter's existence is known from gravitational effects on visible matter and gravitational lensing of background radiation. It was originally hypothesized

According to the gravitational theory of physics, without dark matter, galaxies would col- lapse into separate parts and stars would move in com- pletely

In his paper he concluded that most of the matter in clusters is totally invisi- ble. Zwicky argued that gravity must keep the galaxies in the clus- ter

Dark matter (DM which we know to exist from its influence on cosmological and astrophysical observations, and which is fundamental to the galactic structure

In cosmology, the observed matter in the Universe only accounts for 5% of the observed gravity, while the remaining 26% and 69% are accounted for via dark

Dark matter is needed to explain a variety of observed astronomical phenomena, such as the internal dynamics of galaxies and galaxy clusters, the strength of

Astrophysicists describe dark matter,1 (and more recently dark energy) as invisible mass predicted by the big band theory, yet so far only perceived

26 Feb 2016 A complementary method is the production of dark matter particles at colliders such as the Large Hadron Collider, where they could be observed

1 Dec 2025 25 of this Review, the DM accounts for 26.4% of the critical density in the universe, or 84.4% of the total matter density. The nature of only a
