The effect of the impact of comet Shoemaker Levy‐9 on Jupiter's aurorae [PDF]

open access: yes, 1995
We present infrared spectra and images of the jovian aurorae taken at wavelengths sensitive to the H-3(+) molecular ion during the period around the impact of Comet Shoemaker Levy-9.

The On-orbit Performance of the Colorado Ultraviolet Transit Experiment Mission

open access: yesThe Astronomical Journal, 2023
We present the on-orbit performance of the Colorado Ultraviolet Transit Experiment (CUTE). CUTE is a 6U CubeSat that launched on 2021 September 27 and is obtaining near-ultraviolet (NUV; 2480 Å-3306 Å) transit spectroscopy of short-period exoplanets. The

Microwave Kinetic Inductance Detectors [PDF]

open access: yes, 2005
Low temperature detectors have been a subject of intense interest to the scientific community over the last decade. These detectors work at very low temperatures, often well below 1 Kelvin, to minimize the noise in the measurement of photons.

Estimating the contribution from different ionospheric regions to the TEC response to the solar flares using data from the international GPS network [PDF]

open access: yesAnnales Geophysicae, 2002
This paper proposes a new method for estimating the contribution from different ionospheric regions to the response of total electron content variations to the solar flare, based on data from the international network of two-frequency multichannel ...

Experimental and Analytical Studies of Merging Plasma Loops on the Caltech Solar Loop Experiment [PDF]

open access: yes, 2011
Of crucial importance for magnetized plasmas is magnetic helicity, a topological quantity that measures the knottedness or twistedness of the magnetic field. A universal relaxation theory, applicable to astrophysical and laboratory plasmas, dictates the
