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

open access: yes, 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.

The Rate of Type Ia Supernovae at High Redshift

open access: yes, 2005
We derive the rates of Type Ia supernovae (SNIa) over a wide range of redshifts using a complete sample from the IfA Deep Survey. This sample of more than 100 SNIa is the largest set ever collected from a single survey, and therefore uniquely powerful ...

Black hole quasinormal mode spectroscopy with LISA [PDF]

open access: yes, 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

Adaptive Modulation and Coding Using Neural Network Based SNR Estimation

open access: yesIEEE Access, 2019
In this paper, we propose a novel Adaptive Modulation and Coding (AMC) scheme enabled by Artificial Neural Network (ANN) aided Signal-to-Noise power Ratio (SNR) estimation. The Power Spectral Density (PSD) values are trained for SNR classification and it

Study on the Quality Control for Periodogram in the Determination of Water Level Using the GNSS-IR Technique

open access: yesSensors, 2019
A GNSS station, located on the shore of sea and inland waters, and equipped with standard geodetic receivers and antennas, can be used to measure water levels using a technique called GNSS Interferometric Reflectometry (GNSS-IR).

AKARI Detection of the Infrared-Bright Supernova Remnant B0104-72.3 in the Small Magellanic Cloud

open access: yes, 2007
We present a serendipitous detection of the infrared-bright supernova remnant (SNR) B0104-72.3 in the Small Magellanic Cloud by the Infrared Camera (IRC) onboard AKARI.

Constructive summation of the (2,2) quasi normal mode from a population of black holes [PDF]

open access: yes, 2017
The quasi normal modes (QNMs) associated with gravitational-wave signals from binary black hole (BBH) mergers can provide deep insight into the remnant's properties.
