Otto Stern—An Involuntary Convert to Quantum Theory

Natural Sciences, Volume 6, Issue 2, April 2026.
Otto Stern (1888–1969) at work in his Hamburg laboratory (circa 1930). ABSTRACT The bulk of experiments and observations that lined the path to quantum mechanics amounted to a backlog of data in need of explanation. A notable exception was the Stern–Gerlach experiment (SGE) designed to test the predictions of the old quantum theory as embodied by the ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Improvement of the Target Sensitivity in DECIGO by Optimizing Its Parameters for Quantum Noise Including the Effect of Diffraction Loss

Galaxies, 2021
The DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO) is the future Japanese, outer space gravitational wave detector. We previously set the default design parameters to provide a good target sensitivity to detect the primordial ...

Low-frequency gravitational-wave science with eLISA/NGO [PDF]

, 2012
We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early 2020s. eLISA will survey the low-frequency gravitational-wave sky (from 0.

Characterization of the Outer Uranian Rings in the Visual and Near‐IR Using Keck, JWST, and HST Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present observations of the Uranian outer ring system at near‐infrared and visible wavelengths. Observations with the Keck Telescope were taken in July‐August 2007 at 2.12 and 1.63 μm, when the ring plane was almost edge‐on (ring opening angle B=0.62 $B=0.62$–0.24° ${}^{\circ}$). These data showed, for the first time, the μ ring at infrared

Mars Thermospheric Variability: Disentangling the Influence of Irradiance, Dust, and Dynamics

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present a comprehensive analysis of Martian thermospheric variability using nearly a decade of solar occultation measurements from the MAVEN Extreme Ultraviolet Monitor (EUVM). These data provide vertical profiles of CO2 ${\text{CO}}_{2}$ density and temperature from ∼130 ${\sim} 130$ to 180 km at dawn and dusk, enabling the investigation ...

A wind environment and Lorentz factors of tens explain gamma-ray bursts X-ray plateau

Nature Communications, 2022
The origin of the plateau observed in the early X-ray light curves of gamma ray bursts (GRBs) is debated. Here, the authors show that the observed plateau can be explained within the classical GRB model by considering expanding shell with initial Lorentz
