Microwave Kinetic Inductance Detectors [PDF]

, 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.

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

, 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

Multi-instrument observations of the ionospheric counterpart of a bursty bulk flow in the near-Earth plasma sheet [PDF]

, 2004
International audienceOn 07 September 2001 the Cluster spacecraft observed a "bursty bulk flow" event in the near-Earth central plasma sheet. This paper presents a detailed study of the coincident ground-based observations and attempts to place them ...

A Year-Long Plateau in the Late-Time Near-Infrared Light Curves of Type Ia Supernovae [PDF]

, 2023
The light curves of Type Ia supernovae are routinely used to constrain cosmology models. Driven by radioactive decay of 56Ni, the light curves steadily decline over time, but >150 days after explosion, the near-infrared portion is poorly characterized ...

Discovery of near-ultraviolet counterparts to millisecond pulsars in the globular cluster 47 Tucanae [PDF]

, 2015
We report the discovery of the likely white dwarf companions to radiomillisecond pulsars 47 Tuc Q and 47 Tuc S in the globular cluster 47Tucanae. These blue stars were found in near-ultraviolet images from theHubble Space Telescope for which we derived ...

Multi-wavelength view of the galactic black-hole binary GRS 1716–249 [PDF]

, 2021
The origins of X-ray and radio emissions during an X-ray binary outburst are comparatively better understood than those of ultraviolet, optical and infrared radiation. This is because multiple competing mechanisms – emission from intrinsic and irradiated

Imprints from the solar cycle on the helium atom and helium pickup ion distributions [PDF]

Annales Geophysicae, 2003
Neutral interstellar helium atoms penetrate into the solar system almost unaffected by gas–plasma interactions in the heliospheric interface region, and thus can be considered as carriers of original information on the basic parameters (like ...
