Water Resources Research, Volume 61, Issue 5, May 2025.Abstract This paper reviews the current state of high‐resolution remotely sensed soil moisture (SM) and evapotranspiration (ET) products and modeling, and the coupling relationship between SM and ET. SM downscaling approaches for satellite passive microwave products leverage advances in artificial intelligence and high‐resolution remote sensing using ...

Exploring cosmic origins with CORE: Extragalactic sources in cosmic microwave background maps [PDF]
, 2016 We discuss the potential of a next generation space-borne Cosmic Microwave Background (CMB) experiment for studies of extragalactic sources. Our analysis has particular bearing on the definition of the future space project, CORE, that has been submitted ...

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Imprints of quantum gravity in the cosmic microwave background
European Physical Journal C: Particles and Fields, 2019 It has been shown that the spectrum of quantum gravity contains at least two new modes in addition to the massless graviton: a massive spin-0 and a massive spin-2.

Cosmic Microwave Background Acoustic Peak Locations [PDF]
, 2016 The Planck collaboration has measured the temperature and polarization of the cosmic microwave background well enough to determine the locations of eight peaks in the temperature (TT) power spectrum, five peaks in the polarization (EE) power spectrum and

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

Simons Observatory: Characterization of the Large Aperture Telescope Receiver
The Astrophysical Journal Supplement SeriesThe Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that currently consists of three 0.42 m small-aperture telescopes and one 6 m large-aperture telescope (LAT), located at an elevation of 5200 m in the ...

Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract Current observations show that a significant fraction of the Universe is composed of dark energy and dark matter. In this paper, the simultaneous effects of these dark sectors on the Euler–Heisenberg black hole are investigated, using the quintessence matter field and perfect fluid to model them. In particular, the black hole's thermodynamics,

physica status solidi (a), Volume 222, Issue 5, March 2025.A cost‐effective approach to produce diamond platelets with nitrogen vacancy center (NV) ensemble range is investigated. NVs are generated in industrially produced high‐pressure–high‐temperature type 1b diamonds by high‐energy electron irradiation of 10 MeV and annealing.
