Juno Reveals New Insights Into Io‐Related Decameter Radio Emissions [PDF]

open access: yesJournal of Geophysical Research: Planets, 2020
AbstractThe Juno mission is providing stunning new information about Jupiter and its environment. A new magnetic field model (JRM09) with much improved accuracy near the planet provides the basis for a better understanding of Io‐related decametric radio emissions (DAM) and implications for auroral processes.

Two-color multiphoton emission for comprehensive reveal of ultrafast plasmonic field distribution

open access: yesNew Journal of Physics, 2018
We experimentally demonstrate comprehensive reveal of the ultrafast plasmonic field distribution in a bowtie nanostructure by two-color photoemission electron microscopy (PEEM).

Revealing the sulfur dioxide emission reductions in China by assimilating surface observations in WRF-Chem [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
The anthropogenic emission of sulfur dioxide (SO2) over China has significantly declined as a consequence of the clean air actions. In this study, we have developed a new emission inversion system based on a four-dimensional local ensemble transform ...

An H2CO 6cm Maser Pinpointing a Possible Circumstellar Torus in IRAS18566+0408 [PDF]

open access: yes, 2007
We report observations of 6cm, 3.6cm, 1.3cm, and 7mm radio continuum, conducted with the Very Large Array towards IRAS18566+0408, one of the few sources known to harbor H2CO 6cm maser emission. Our observations reveal that the emission is dominated by an

Mutation effect of acoustic and electromagnetic emissions of hard rock impact failure

open access: yesInternational Journal of Distributed Sensor Networks, 2019
To reveal acoustic emission and electromagnetic emission effects during hard rock impact failure is a crucial issue for monitoring and warning rockburst risk induced by hard roof fracture and fall.

Detection of X-ray line emission from the shell of SNR B0540-69.3 with XMM-Newton RGS [PDF]

open access: yes, 2000
We present X-ray observations of PSR 0540-69.3 with the XMM-Newton observatory. The spectra obtained with the Reflection Grating Spectrometer reveal, for the first time, emission from ionized species of O, Ne and Fe originating from the SNR shell ...

Capacitive effect in ultrafast laser-induced emission from low conductance diamond nanotips

open access: yesNew Journal of Physics, 2020
Single crystal diamond nanotips reveal a new behavior for ultrafast laser-induced electron emission. Under tightly focused femtosecond laser illumination, electron yield shows a saturation with the laser intensity. When the DC bias is sufficient for dark

First optical light from the supernova remnant G 17.4-2.3 [PDF]

open access: yes, 2002
Deep optical CCD images of the supernova remnant G 17.4-2.3 were obtained and faint emission has been discovered. The images, taken in the emission lines of Halpha+[N II], [S II] and [O III], reveal filamentary structures in the east, south-east area ...

Weak Biophoton Emission Reveals Gateway To The Past

open access: yes, 2022
Our team has spent over 20 years gathering observational data from citizen scientists and conducting research and development to create a new approach to learning called "quantum social learning" or QSL. QSL focuses on the most subtle aspects of human experience, known as qualia, which include intuitions, thoughts, feelings, sensations, and perceptions.

The large scale distribution of warm ionized gas around nearby radio galaxies with jet-cloud interactions [PDF]

open access: yes, 2000
Deep, narrow-band Halpha observations taken with the TAURUS Tunable Filter (TTF) on the 4.2m WHT telescope are presented for two nearby radio galaxies with strong jet-cloud interactions. Although the brightest emission line components are closely aligned
