The Monoceros radio loop: Temperature, brightness, spectral index, and distance

Abstract

In this paper we estimated the temperatures and brightnesses of the Monoceros radio loop at 1420, 820 and 408 MHz. The linear spectrum is estimated for mean temperatures versus frequency between 1420, 820 and 408 MHz. The spectral index of Monoceros loop is also obtained. The brightness temperatures and surface brightnesses of the loop are computed using data taken from radio‐continuum surveys at the three frequencies. The spectral index of the loop is also obtained from T‐T plots between 1420–820, 1420–408, and 820–408 MHz. The obtained results confirm non‐thermal origin of the Monoceros radio loop (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

XMM–Newton observations of a gamma-ray pulsar J0633+0632: pulsations, cooling and large-scale emission

“…Most estimates are about 1.6 kpc (e.g. Borka Jovanović & Urošević 2009), which is compatible with the distance to the Rosette Nebula. It was assumed that these objects are interacting (see Xiao & Zhu 2012, and references therein).…”

Chandra measurements of the proper motion of the γ-ray pulsar J0633+0632

“…In figure 2, we present an image of the Rosette Nebula and the Monoceros Loop (G205.5+0.5) supernova remnant (SNR). The latter is a large shell-type middle-aged (30-150 kyr) SNR which may interact with the Rosette Nebula [10,11]. Using the pulsar proper motion, we constrained coordinates of the pulsar birth cite.…”
