Supernova remnant G53.41+0.03 investigated in detail

Astronomers have carried out detailed X-ray observations of a not too long ago found supernova remnant (SNR) generally known as G53.41+0.03. Outcomes of the observational marketing campaign present essential insights into the properties of this object. The examine was detailed in a paper printed Might 7 on the arXiv pre-print server.

SNRs are diffuse, increasing constructions ensuing from a supernova explosion. They comprise ejected materials increasing from the explosion and different interstellar materials that has been swept up by the passage of the shockwave from the exploded star.

Research of supernova remnants are essential for astronomers, as they play a key function in the evolution of galaxies, dispersing the heavy components made in the supernova explosion and offering the power wanted for heating up the interstellar medium (ISM). SNRs are additionally believed to be liable for the acceleration of galactic cosmic rays.

G53.41+0.03 was confirmed as a supernova remnant in 2018 by analyzing the info from the LOFAR (LOw Frequency ARray) Two-meter Sky Survey. The SNR has a comparatively younger age and is estimated to be positioned some 24,450 mild years away.

Provided that the character of G53.41+0.03 remains to be poorly understood, a bunch of astronomers led by Vladimír Domček of the College of Amsterdam, the Netherlands, determined to take a better have a look at this SNR. Utilizing ESA’s XMM-Newton spacecraft, they carried out X-ray observations of this object with the principle goal of investigating its morphological construction.

“On this work, we comply with up SNR G53.41+0.03 with a brand new devoted 70ks XMM-Newton statement,” the astronomers wrote in the paper.

The observations discovered that G53.41+0.03 has a half-shell morphology of three.5′ in measurement with a lot of the emission coming from the higher half (in galactic coordinates). The decrease half of the SNR doesn’t present any clear morphological detection. The scale of the remnant in X-rays turned out to be smaller than in the radio band, which is most definitely attributable to a excessive picture decision supplied by XMM-Newton.

The examine recognized three distinctive areas of the remnant, all nicely characterised by the non-equilibrium ionization plasma mannequin. These areas showcase variations in their brightness and plasma traits. The astronomers assume that that is possible attributable to the upper density in the brightest area and a mix of decrease density and the proximity to the galactic airplane in the faintest area.

Moreover, the spectral evaluation revealed that G53.41+0.03 is between 1,000 and 5,000 years outdated, which confirms the comparatively younger age of this SNR. The observations additionally discovered two fascinating level sources in the geometrical heart of G53.41+0.03. Certainly one of these sources is a younger stellar object (YSO), whereas the second seems to be a magnetar, nonetheless additional investigation of this supply are wanted in order to reveal its nature.
