Illumination Model of Lunar Terrain around Lunar Laser Retroreflectors Based on LOLA Data

Remote Sensing
Lunar laser retroreflectors are a crucial target for lunar laser ranging (LLR). During LLR operations at all lunar laser ranging stations, the considerable distance between the Earth and the Moon makes it impossible to visually identify the position of ...

Toward Robust Detections of Nanohertz Gravitational Waves

The Astrophysical Journal, 2023
The recent observation of a common red-noise process in pulsar timing arrays (PTAs) suggests that the detection of nanohertz gravitational waves might be around the corner.

Saltier Than Expected – Small Brine Discharge Increases Salt Intrusion in the Tidal Ems Estuary, North Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract This study investigates the long‐term salinity dynamics of the partially mixed Ems Estuary, focusing on the influence of brine inflow on salt intrusion. Salinity time series from eight monitoring sites (2000–2023) were analyzed to assess variations due to river discharge and brine inflow from two injection sites.

Three Drivers of 21st‐Century Changes in Ocean Tides

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Numerical model simulations are conducted to study the response of barotropic ocean tides to 21st‐century climate change, as manifested by sea level rise, increasing ocean stratification, and expanding Antarctic ice shelf cavities. Emphasis is placed on surface elevations, with projections of M2 ${\mathrm{M}}_{2}$, S2 ${\mathrm{S}}_{2}$, K1 ${\

3D Localization of FRB 20190425A for Its Potential Host Galaxy and Implications

The Astrophysical Journal
Fast radio bursts (FRBs) are high-energy, short-duration phenomena in radio astronomy. Identifying their host galaxies can provide insights into their mysterious origins. In this paper, we introduce a novel approach to identifying potential host galaxies

Mountain Degradation Mechanisms on Io Based on Geologic Mapping of the Cocytus Montes Region From JunoCam Imagery

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Periodic high‐resolution imagery of Io is essential for understanding its surface evolution, from volcanic eruptions to tectonic deformation to large‐scale mass wasting. Juno flybys in 2023 and 2024 obtained imagery of the surface with the JunoCam imager at 1.8 km/pixel spatial resolution, comparable to global observations from the Galileo ...

Dealing with data gaps for TianQin with massive black hole binary signal

European Physical Journal C: Particles and Fields
Space-borne gravitational wave detectors like TianQin might encounter data gaps due to factors like micro-meteoroid collisions or hardware failures. Such events will cause discontinuity in the data, presenting challenges to the data analysis for TianQin,
