Radio spectral characteristics of the supernova remnant Puppis A and nearby sources
(Oxford University Press, 2015-08)
This paper presents a new study of the spectral index distribution of the supernova remnant (SNR) Puppis A. The nature of field compact sources is also investigated according to the measured spectral indices. This work is ...
Feature-tailored spectroscopic analysis of the SNRsupernova remnant Puppis A in X-rays
(EDP Sciences, 2016-05)
We introduce a distinct method to perform spatially-resolved spectral analysis of astronomical sources with highly structured X-ray emission. The method measures the surface brightness of neighbouring pixels to adaptively ...
A high resolution HI study towards the supernova remnant Puppis A and its environments
(Wiley Blackwell Publishing, Inc, 2017-01)
We observed the supernova remnant (SNR) Puppis A in the 21 cm line with the Australia Telescope Compact Array with the aim of determining the systemic velocity and, hence, the corresponding kinematic distance. For the ...
New perspectives on the supernova remnant Puppis A based on a radio polarization study
(Wiley Blackwell Publishing, Inc, 2018-06)
We present a polarization study towards the supernova remnant (SNR) Puppis A based on original observations performed with the Australia Telescope Compact Array. Based on the analysis of a feature detected outside the SNR ...
Observations of the neutral hydrogen surrounding the radio-quiet neutron star RX J0822-4300 in Puppis A
(Oxford University Press, 2003-10)
We have observed the H i distribution in an area 40 × 40 arcmin2 around the neutron star candidate RX J0822–4300, which is located in the supernova remnant Puppis A. The observations of the λ21-cm line were obtained with ...
