We review the physics opportunities of the Future Circular Collider, covering its e+ e-, pp, ep
and heavy ion programmes. We describe the measurement capabilities of each FCC …

Abstract The James Webb Space Telescope (JWST) is a large (6.6 m), cold (< 50 K), infrared
(IR)-optimized space observatory that will be launched early in the next decade into orbit …

The possibility that the dark matter comprises primordial black holes (PBHs) is considered,
with particular emphasis on the currently allowed mass windows at 1 0 16–1 0 17 g, 1 0 20 …

Abstract Primordial Black Holes (PBH) could be the cold dark matter of the universe. They
could have arisen from large (order one) curvature fluctuations produced during inflation that …

In this paper we present a new scenario where massive primordial black holes (PBHs) are
produced from the collapse of large curvature perturbations generated during a mild …

We update the constraints on the fraction of the Universe going into primordial black holes in
the mass range 10 9–10 17 g associated with the effects of their evaporations on big bang …

Aims. The EROS-2 project was designed to test the hypothesis that massive compact halo
objects (the so-called “machos”) could be a major component of the dark matter halo of the …

We report on our search for microlensing toward the Large Magellanic Cloud (LMC).
Analysis of 5.7 yr of photometry on 11.9 million stars in the LMC reveals 13–17 microlensing …

Abstract The Nancy Grace Roman Space Telescope (Roman) will perform a Galactic
Exoplanet Survey (RGES) to discover bound exoplanets with semimajor axes greater than 1 …
