Observations of the post shock break-out emission of SN 2011dh with XMM-Newton [PDF]

open access: yes, 2012
After the occurrence of the type cIIb SN 2011dh in the nearby spiral galaxy M 51 numerous observations were performed with different telescopes in various bands ranging from radio to gamma-rays.

Spectrum of Singly Charged Uranium (U II) : Theoretical Interpretation of Energy Levels, Partition Function and Classified Ultraviolet Lines

open access: yesAtoms, 2017
In an attempt to improve U II analysis, the lowest configurations of both parities have been interpreted by means of the Racah-Slater parametric method, using Cowan codes.

The re-emission spectrum of digital hardware subjected to EMI [PDF]

open access: yes, 2003
The emission spectrum of digital hardware under the influence of external electromagnetic interference is shown to contain information about the interaction of the incident energy with the digital circuits in the system.

The sudden appearance of CO emission in LHA 115-S 65 [PDF]

open access: yes, 2012
Molecular emission has been detected in several Magellanic Cloud B[e] supergiants. In this Letter, we report on the detection of CO band head emission in the B[e] supergiant LHA 115-S 65, and present a K-band near-infrared spectrum obtained with the ...

InPBi Quantum Dots for Super-Luminescence Diodes

open access: yesNanomaterials, 2018
InPBi thin film has shown ultra-broad room temperature photoluminescence, which is promising for applications in super-luminescent diodes (SLDs) but met problems with low light emission efficiency.

Nitride superluminescent diodes with broadened emission spectrum fabricated using laterally patterned substrate.

open access: yesOptics Express, 2016
We demonstrate InGaN/GaN superluminescent diodes with broadened emission spectra fabricated on surface-shaped bulk GaN (0001) substrates. The patterning changes the local vicinal angle linearly along the device waveguide, which results in an indium ...

Tailoring emission spectra by using microcavities

open access: yesResults in Physics, 2019
We present a theoretical model to describe emission spectrum of an emitter in a micro-cavity. Our model proposes that the spectrum in a metal micro-cavity depends on the product of the emission spectrum in free space and the local density of states (LDOS)

On the Integrated Spectrum of the X-ray Binaries and the Origin of Soft X-ray Emission from the Bulge of M31 [PDF]

open access: yes, 2000
Using ROSAT PSPC data, we have performed several tests aimed at understanding the origin of the soft X-ray spectral component detected from the bulge of M31.

The emission spectrum of curium [PDF]

open access: yesAtomic Data and Nuclear Data Tables, 1976
Abstract The curium emission spectrum was observed from 2400 to 11 200 A using electrodeless lamps as sources. Accurately measured wavelengths of 2034 of the strongest 244 Cm lines are reported. The wavelengths, wavenumbers, and relative intensities are given.

Emission spectrum of the driven nonlinear oscillator [PDF]

open access: yes, 2012
Motivated by recent "circuit QED" experiments we investigate the noise properties of coherently driven nonlinear resonators. By using Josephson junctions in superconducting circuits, strong nonlinearities can be engineered, which lead to the appearance ...
