Gravitational Waves from Phase Transition of Accreting Neutron Stars [PDF]

open access: yes, 1997
We propose that when neutron stars in low-mass X-ray binaries accrete sufficient mass and become millisecond pulsars, the interiors of these stars may undergo phase transitions, which excite stellar radial oscillations.

The role of thermal stratification on the co‐spectral properties of momentum transport above an Amazonian forest

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
Using micrometeorological measurements in Brazil at the Amazon Tall Tower Observatory, the scalewise impact of thermal stratification on turbulent momentum fluxes is explored in the roughness sublayer and the atmospheric surface layer. A scalewise co‐spectral budget model developed here revealed that the turbulent momentum co‐spectrum Fwu(kx)$$ {F}_{wu}

Can the Gravitational Wave Background from Inflation be Detected Locally?

open access: yes, 1993
The Cosmic Background Explorer (COBE) detection of microwave background anisotropies may contain a component due to gravitational waves generated by inflation.

Swope Supernova Survey 2017a (SSS17a), the Optical Counterpart to a Gravitational Wave Source

open access: yes, 2017
On 2017 August 17, the Laser Interferometer Gravitational-wave Observatory (LIGO) and the Virgo interferometer detected gravitational waves emanating from a binary neutron star merger, GW170817.

Airborne Lidar to Verify ICESat‐2 Arctic Summer Sea Ice Heights and Melt Pond Depths: Calibration and Validation Campaign, Greenland 2022

open access: yesEarth and Space Science, Volume 12, Issue 10, October 2025.
Abstract In July 2022, the National Aeronautics and Space Administration (NASA) funded an airborne lidar data acquisition campaign over the central Arctic Ocean to evaluate ICESat‐2 ATLAS (Ice, Cloud, and Land Elevation Satellite, Advanced Topographic Laser Altimeter System) retrievals of summer sea ice heights and melt pond characteristics.

VLBA Astrometry of the Fastest-spinning Magnetar Swift J1818.0−1607: A Large Trigonometric Distance and a Small Transverse Velocity

open access: yesThe Astrophysical Journal Letters
In addition to being the most magnetic objects in the known Universe, magnetars are the only objects observed to generate fast-radio-burst-like emissions. The formation mechanism of magnetars is still highly debated and may potentially be probed with the

Kinematic Evolution of the Cephalonia‐Lefkada Transform Fault Zone: Strain Partitioning in Response to Subduction Margin Dynamics

open access: yesTectonics, Volume 44, Issue 10, October 2025.
Abstract The eastern Adriatic margin is composed by an Ocean‐Continent Transition lithosphere (OCT), resulting in the southwards along‐strike variation from collision to subduction. The Cephalonia‐Lefkada Transform Fault zone (CTF) is a right‐lateral strike‐slip fault system located above the OCT and associated to this kinematic transition.
