TL;DR
This paper presents detailed X-ray, radio, and infrared observations of the Mouse pulsar wind nebula powered by pulsar J1747-2958, revealing its structure, spectrum, and electron cooling processes, and providing insights into its magnetic field and flow dynamics.
Contribution
It offers the first combined multiwavelength analysis of the Mouse PWN, including spatially-resolved spectroscopy and modeling of electron cooling and magnetic field properties.
Findings
The PWN exhibits a spectral steepening along the X-ray tail.
The tail's integrated spectrum fits a single power-law with photon index 2.09.
Multiwavelength data suggest synchrotron cooling and a broken power-law spectrum.
Abstract
The young energetic pulsar J1747-2958 ( kyr, erg s) powers the Mouse pulsar wind nebula (PWN), famous for its spectacular tail spanning 45 in X-rays and 12 in radio ( kpc). We present the results of Chandra observations of the PWN and the analysis of archival lower-frequency data. The Chandra HRC image reveals a point-like source at the pulsar position, 1 behind the bow shock apex of the PWN. The flattened appearance of the compact nebula is consistent with an equatorial outflow deformed by the ram pressure, implying that the angle between the pulsar's spin axis and line of sight is (in agreement with the radio and -ray pulse profiles). The spatially-resolved spectroscopy with Chandra ACIS shows that the power-law (PL) spectrum steepens from to over the 45…
