Radio Emission From Snr 1987A [PDF]

International Astronomical Union Colloquium, 1994
AbstractDiffusive acceleration of electrons by the blast wave of SNR 1987A is shown to provide a reasonable fit to observations of the radio emission since it reappeared in 1990 July. As well as determining the diffusion coefficient in this model, the observations indicate that the compression ratio of the gas subshock embedded in the blast wave is ~2 ...

Emission Measures and Emission-measure-weighted Temperatures of Shocked ISM and Ejecta in Supernova Remnants

, 2019
A goal of supernova remnant (SNR) evolution models is to relate fundamental parameters of a supernova (SN) explosion and progenitor star to the current state of its SNR.

SnR Evaluation Framework

, 2021
Purpose of this SnR evaluation framework is to provide guidance on a structured evaluation process for all use cases to evaluate all technology components developed under the SnR project. In order to achieve this, a set of KPIs has been formulated for each individual technology component.

X-ray/Optical/Radio Observations of a Resolved Supernova Remnant in NGC 6822

, 2004
The supernova remnant (SNR), Ho 12, in the center of the dwarf irregular galaxy NGC 6822 was previously observed at X-ray, optical, and radio wavelengths.

Throughput improvement on bidirectional Fano algorithm [PDF]

, 2010
Recently, we introduced a bidirectional Fano algorithm (BFA) [10] which can achieve much higher decoding throughput compared to the regular unidirectional Fano algorithm (UFA), especially at low signal-to-noise-ratio (SNR).

Modeling SNR G1.9+0.3 as a Supernova Inside a Planetary Nebula [PDF]

, 2015
Using 3D numerical hydrodynamical simulations we show that a type Ia supernova (SN Ia) explosion inside a planetary nebula (PN) can explain the observed shape of the G1.9+0.3 supernova remnant (SNR) and its X-ray morphology.

Chronic stress-induced neurodegenerative changes in Wistar rats: Hippocampal evidence and the mitigating effects of Allium Sativum

Babcock University Medical Journal
Objective: Stress triggers a biological response perceiving a threat, chemicals and hormones surge throughout the body, after long-term exposure, stress accelerates cell ageing, immune senescence, and some age-related diseases such as neurodegenerative ...

Detection performance analysis of hybrid MIMO radar

The Journal of Engineering, 2019
This study focuses on the detection performance analysis of a notional hybrid MIMO radar, which can be seen as a combination of the phased-array and distributed MIMO radars.

The molecular clump towards the eastern border of SNR G18.8+0.3

, 2012
The eastern border of the SNR G18.8+0.3, close to an HII regions complex, is a very interesting region to study the molecular gas that it is probably in contact with the SNR shock front.

Black hole quasinormal mode spectroscopy with LISA [PDF]

, 2009
The signal-to-noise ratio (SNR) for black hole quasinormal mode sources of low-frequency gravitational waves is estimated using a Monte Carlo approach that replaces the all-sky average approximation. We consider an eleven dimensional parameter space that
