The Astrophysical Journal, 2023 Scintillation of pulsar radio signals caused by the interstellar medium can in principle be used for interstellar interferometry. Changes in the dynamic spectra as a function of pulsar longitude were in the past interpreted as having spatially resolved ...

Interstellar scintillation of PSR J0437–4715 [PDF]
Astronomy & Astrophysics, 2006 We studied the turbulence spectrum of the local interstellar plasma in the direction of PSR J0437-4715, on the basis of our observations and those reported earlier by others. We combine these data to form a structure function for the variations of phase along the line of sight to the pulsar.

Pulsar Investigation Using Interstellar Scintillation [PDF]
International Astronomical Union Colloquium, 2001 AbstractWe discuss the resolution of pulsar magnetospheres using interstellar scintillation. The two-dimensional spatial structure of pulsar emission zones can be obtained from analysis of diffractive scintillations at low frequencies. Based on refractive and diffractive scintillation of pulsars we can also reconstruct the distribution of turbulent ...

Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]
, 2008 We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

The Reaction of Muonium with Hydrogen Peroxide in Aqueous Solution
ChemPhysChem, Volume 24, Issue 21, November 2, 2023., 2023 Experimental data on muonium kinetics in water greatly expands the set of experimental data on kinetic isotope effects in the reactions of H atoms with H2O2 and its conjugate base HOO−. Abstract Rate constants for the reactions of muonium (Mu) (the ultralight isotope of the hydrogen atom) with H2O2 in H2O and D2O2 in D2O have been determined at various

Space Weather, Volume 21, Issue 10, October 2023., 2023 Abstract We have conducted a blind search in 49 consecutive days of interplanetary scintillation observations made by the Murchison Widefield Array from mid‐2019, with overlapping daily observations approximately East and South‐East of the Sun at an elongation of ∼30° and a field of view of 30°.

Unfolding the Neutron Flux Spectrum on the Surface of Mars Using the MSL‐RAD and Odyssey‐HEND Data
Space Weather, Volume 21, Issue 8, August 2023., 2023 Abstract Understanding the long‐term radiation environment at the surface of Mars allows us to estimate the exposure for future robotic and crewed missions. Typically, the radiation environment includes charged particles (i.e., protons and heavier ions) and neutral particles (i.e., gamma rays and secondary neutrons).

Interstellar Scintillation of Radio Sources as a Probe for Investigations of the Local Interstellar Medium [PDF]
International Astronomical Union Colloquium, 1997 AbstractA possibility of obtaining information on small scale inhomogeneities of the electron component of the local interstellar medium (LISM) is investigated using interstellar scintillations of extragalactic radio sources. We analyse Culgoora array observational data on variability of 190 extragalactic radio sources, covering most of the sky, at 80 ...

Following the Path of Least Resistance
Perspectives of Earth and Space Scientists, Volume 3, Issue 1, December 2022., 2022 Abstract The reason a path may be the path of least resistance is because it may be the path for which you are most suited. For you it may look like a stroll in the park; for someone else, it may look like climbing Everest. Or vice versa. Taking the “easy” route is not copping out; it is a form of playing to your strength. Here I detail my professional
