Refractive scintillation in the interstellar medium
The Astrophysical Journal, 1987 It is shown here that the large-scale component of interstellar scintillation which causes the slow variation in the apparent intensity of pulsars on time scales of days to months can be greatly enhanced when the turbulence spectrum has a limiting inner scale of the order 10 to the 9th m.

Using Giant Pulses to Measure the Impulse Response of the Interstellar Medium
The Astrophysical Journal, 2023 Giant pulses emitted by PSR B1937+21 are bright, intrinsically impulsive bursts. Thus, the observed signal from a giant pulse is a noisy but direct measurement of the impulse response from the ionized interstellar medium.

The Interstellar Scintillation of PSR J1614-2230 [PDF]
, 2023 Observations of the millisecond pulsar J1614-2230 as part of the NANOGrav 12.5 yr dataset were utilised to study the scintillation and interstellar medium along the line of sight of PSR J1614-2230.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The Radiation Assessment Detector (RAD) on the Curiosity rover has been characterizing the Martian surface radiation field since 2012. The dose observed by RAD is influenced by a variety of factors, including an essential one, the terrain. After parking near Murray Buttes in September 2016 where it first detected a ∼5% decrease in dose rate ...

Investigation of Interstellar Scintillation of the Millisecond Pulsar B1937+21 with the FAST
The Astrophysical JournalPulsar scintillation serves as a valuable tool for investigating interstellar scattering screens and their properties. In this paper, we report on multiepoch interstellar scintillation from the millisecond pulsar B1937+21 (J1939+2134) using Five-hundred ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements
Space Weather, Volume 24, Issue 3, March 2026.Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks.
