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 ...

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).

Detailed study of the microwave emission of the supernova remnant 3C 396 [PDF]

open access: yes, 2016
We have observed the supernova remnant 3C~396 in the microwave region using the Parkes 64-m telescope. Observations have been made at 8.4 GHz, 13.5 GHz, and 18.6 GHz and in polarisation at 21.5 GHz.

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.

Carrier Dynamics in Submonolayer InGaAs/GaAs Quantum Dots [PDF]

open access: yes, 2006
Carrier dynamics of submonolayer (SML) InGaAs/GaAs quantum dots (QDs) were studied by micro-photoluminecence (MPL), selectively excited photoluminescence (SEPL), and time-resolved photoluminescence (TRPL).

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

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

The Spatial and Emission Properties of the Large [O iii] Emission Nebula Near M31

open access: yesThe Astrophysical Journal, 2023
Drechsler et al. reported the unexpected discovery of a 1.°5 long [O iii ] emission nebula 1.°2 southeast of the M31 nucleus. Here we present additional images of this large emission arc, called the Strottner–Drechsler–Sainty Object (SDSO), along with ...

Emission from Bow Shocks of Beamed Gamma-Ray Bursts [PDF]

open access: yes, 2000
Beamed gamma-ray burst (GRB) sources produce a bow shock in their gaseous environment. The emitted flux from this bow shock may dominate over the direct emission from the jet for lines of sight which are outside the angular radius of the jet emission ...
