Clustering at high redshift

, 2002
The addition of deep near infrared images to the database provided by the HDF-S WFPC2 is essential to monitor the SEDs of the objects on a wide baseline and address a number of key issues including the total stellar content of baryonic mass, the effects ...

Crustal Heat Flow Drives the Earthquake Magnitude Distribution

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Earthquake magnitude‐frequency distributions exhibit significant space‐time variations, which can provide critical insights into the physical processes driving seismicity. Understanding these variations is crucial for assessing seismic hazards and uncovering the physical processes driving earthquakes.

A Possible Solution to the Mystery of the ANITA Anomalous Events

Annalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Environmental history of filament galaxies

Astronomy & Astrophysics
Galaxy properties, such as stellar mass and star formation rate, correlate with their position within the cosmic web. Although galaxy properties can be correlated with a specific environment at a certain cosmic epoch, they may have experienced different ...

A Common Mantle Source for the Endogenous CO2 Degassed at the Eifel (Western Germany) and the Ardennes (Eastern Belgium) Regions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Tectonic CO2 Earth degassing is globally relevant and has probably controlled climate on a geological scale (Brune et al., 2019, https://doi.org/10.1038/s41561‐017‐0003‐6). Endogenous CO2 outgassing from rifting areas remains poorly constrained, with most available data from the East African Rift.

Extended X-ray emission around RRAT J1819-1458

, 2012
We present new imaging and spectral analysis of the recently discovered extended X-ray emission around the high-magnetic-field rotating radio transient RRAT J1819-1458. We used two Chandra observations, taken on 2008 May 31 and 2011 May 28. The diffuse X-

GLADE: Gravitational Light-Bending Astrometry Dual-Satellite Experiment

Applied Sciences
Light bending is one of the classical tests of general relativity and is a crucial aspect to be taken into account for accurate assessments of photon propagation. In particular, high-precision astrometry can constrain theoretical models of gravitation in
