The lensing and temperature imprints of voids on the cosmic microwave background. [PDF]

open access: yes, 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.

Deciphering Pleistocene Fault Activity in the Eastern Alps: Dating Fault Gouges With Electron Spin Resonance and Optically Stimulated Luminescence

open access: yesTectonics, Volume 44, Issue 8, August 2025.
Abstract The Eastern Alps have been influenced by post‐collisional indentation tectonics since the Miocene. Currently, Adria‐Europe convergence, albeit slow, is accommodated and distributed across several faults. The seismogenic potential of some of these faults is unclear. We applied optically stimulated luminescence (OSL) and electron spin resonance (

Imprints of quantum gravity in the cosmic microwave background

open access: yesEuropean 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]

open access: yes, 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

Revisiting Sub‐Surface Drought Cascades With Daily Satellite Observations of Soil Moisture and Terrestrial Water Storage

open access: yesWater Resources Research, Volume 61, Issue 8, August 2025.
Abstract The increasing frequency, intensity, and duration of extreme heat and drought events in a warming climate make it crucial to understand the relationship between surface and subsurface water storage dynamics during these events. Changes in water storage can be studied globally using satellite observations.

Simons Observatory: Characterization of the Large Aperture Telescope Receiver

open access: yesThe Astrophysical Journal Supplement Series
The 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 ...

Planck intermediate results. LI. Features in the cosmic microwave background temperature power spectrum and shifts in cosmological parameters [PDF]

open access: yes, 2016
The six parameters of the standard $\Lambda$CDM model have best-fit values derived from the Planck temperature power spectrum that are shifted somewhat from the best-fit values derived from WMAP data.

Analysis, Testing, and Design of a UHF and HF Peer‐to‐Peer Communication System for the Europan Cryosphere

open access: yesEarth and Space Science, Volume 12, Issue 8, August 2025.
Abstract This study presents a validated design of a dual‐band wireless relay system of “pucks” for through‐ice communication between a cryobot and a surface lander during a future exploration of the Europan cryosphere. The design of a terrestrial demonstration system and the results of a 103 m through‐ice system test in a relevant environment near ...
