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 (

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.

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.

Separation of Correlated Astrophysical Sources Using Multiple-Lag Data Covariance Matrices

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
This paper proposes a new strategy to separate astrophysical sources that are mutually correlated. This strategy is based on second-order statistics and exploits prior information about the possible structure of the mixing matrix.

Cosmic Microwave Background Polarization Analysis [PDF]

open access: yes, 2008
With polarization of the cosmic microwave background (CMB) now detected, and confirmed by several independent experiments, the next goal is to characterise accurately its statistical properties. In these lecture notes we review the physical motivation for pursuing CMB polarization, and the basic statistical properties of the polarization fields.

Forecast of Foreground Cleaning Strategies for AliCPT-1

open access: yesThe Astrophysical Journal Supplement Series
We report the test results of several independent foreground cleaning pipelines used in the Ali CMB Polarization Telescope experiment (AliCPT-1), a high-altitude cosmic microwave background (CMB) imager in the Northern Hemisphere with thousands of ...

Betti Functionals as Probes for Cosmic Topology

open access: yesUniverse
The question of the global topology of the Universe (cosmic topology) is still open. In the ΛCDM concordance model, it is assumed that the space of the Universe possesses the trivial topology of R3, and thus that the Universe has an infinite volume.
