Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

We present results from an analysis of all data taken by the bicep2/Keck CMB polarization
experiments up to and including the 2015 observing season. This includes the first Keck …

Abstract We reconstruct the Cosmic Microwave Background (CMB) lensing potential on the
latest Planck CMB PR4 (NPIPE) maps, which include slightly more data than the 2018 PR3 …

Axions comprise a broad class of particles that can play a major role in explaining the
unknown aspects of cosmology. They are also well-motivated within high energy physics …

Thanks to its broad energy range, excellent sensitivity, and all-sky monitoring capabilities,
the Fermi Gamma-ray Space Telescope Large Area Telescope (LAT) has revolutionized our …

We show how the success of deep learning could depend not only on mathematics but also
on physics: although well-known mathematical theorems guarantee that neural networks …

Mass and radius are two of the most fundamental properties of an astronomical object.
Increasingly, new planet discoveries are being announced with a measurement of one of …

Cosmological models in which dark matter consists of cold elementary particles predict that
the dark halo population should extend to masses many orders of magnitude below those at …

In recent decades, several detector technologies have been developed with the quest to
directly detect dark matter interactions and to test one of the most important unsolved …
