A Timing View of the Additional High-energy Spectral Component Discovered in the Black Hole Candidate Swift J1727.8-1613

The Astrophysical Journal Letters
We present an energy-dependent analysis for the type-C quasiperiodic oscillations (QPOs) observed in the black hole X-ray binary Swift J1727.8–1613 using Insight-HXMT observations.

Orbital Variability in Grazing Proportion: New Insights From Sedimentary Amino Acid δ15N Records of the Western Equatorial Pacific

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The carbon sequestration capacity of the biological carbon pump (BCP) is determined by surface ocean carbon fixation and the transportation of fixed carbon to the ocean interior, which is closely linked to the trophic structure of planktonic ecosystem.

Degenerate Neutron Capture Rates in the Threshold of Neutron Star–Black Hole Mergers

The Astrophysical Journal
We first show that the rate of energy generation due to neutron capture rates can be important in neutron star–black hole mergers (NS–BH mergers) by considering neutron degeneracy.

Tectonics as a Regulator of Shoreline Retreat and Rocky Coast Evolution Across Timescales

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Rocky coast morphology is shaped by interactions between wave action, sea level, and tectonics over millennial time scales. However, a clear and quantifiable signature of tectonic uplift on decadal to centennial shoreline retreat rates is outstanding.

Driven Collisionless Reconnection of Force-free Flux Tubes: From Onset to Coalescence

The Astrophysical Journal
We investigate the onset of driven collisionless reconnection and plasmoid formation in a magnetically dominated pair plasma, using 2D particle-in-cell simulations.
