Cosmic microwave background constraints on primordial black hole dark matter [PDF]
, 2016 We revisit cosmic microwave background (CMB) constraints on primordial black hole dark matter. Spectral distortion limits from COBE/FIRAS do not impose a relevant constraint. Planck CMB anisotropy power spectra imply that primordial black holes with mBH≳

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract The Galilean satellite Europa is a primary candidate for the study of ocean worlds. In anticipation of NASA's Europa Clipper and ESA's JUICE missions, we revisit the magnetic field measurements of the Galileo spacecraft. The ocean's induction response is governed by its induction amplitude and phase shift, which are a function of the ocean ...

Tropical Tropopause Layer Evolution During QBO Disruptions
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.Abstract The tropical tropopause layer (TTL) is studied during 2015/16 and 2019/20 quasi‐biennial oscillation (QBO) disruption events using GNSS‐RO and SWOOSH satellite observations and the ERA5 reanalysis. By compositing temperature, water vapor, and tropical upwelling during different phases of QBO and QBO disruptions (XQBO), we show that XQBO events

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.

The lensing and temperature imprints of voids on the cosmic microwave background. [PDF]
, 2016 We have searched for the signature of cosmic voids in the cosmic microwave background (CMB), in both the Planck temperature and lensing-convergence maps; voids should give decrements in both.

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.Abstract High‐resolution geospatial soil moisture measurements are needed to inform hydrological modeling and to guide water management in agriculture, especially in highly heterogeneous systems such as micro‐irrigated orchards. In this research, we used a Portable L‐band Radiometer (PoLRa) to map very high‐resolution (<2 m) soil surface moisture in ...

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 ...

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
