Source Notes:

From H.E.S.S. Collaboration (2015):
- "(the detection) coincides with the superbubble 30 Dor C, the first
such source detected in VHE gamma rays"

This detection was announced at the Fermi Symposium by Komin et al. (2014):
- "H.E.S.S., with its superior angular resolution of about 0.05
degrees, can separate individual sources in the LMC. In this talk we
will present the result of 210 h observations with the H.E.S.S.
telescopes. Besides the already known PWN N 157B, these observations
establish significant VHE gamma-ray emission from the superbubble
30 Dor C and show evidence for emission from the supernova remnant (SNR) N 132D.

Positional Information:
150128: The position was updated from the SIMBAD one.
From H.E.S.S. Collaboration (2015):
- R.A. (J2000): 05 35 55 +/- 5s
- Dec. (J2000): -69 11 10 +/- 20"

Spectral Information:
From H.E.S.S. Collaboration (2015):
- spectral index: 2.6 +/- 0.2(stat) +/- 0.3(syst)

Distance:
From H.E.S.S. Collaboration (2015):
- the distance to the Large Magellenic Cloud, where this superbubble
lies, is approximately 50 kpc

Source properties:
From Kavanagh et al. (2018):
- "The 30 Dor C superbubble is unique for its synchrotron X-ray shell,
as well as being the first superbubble to be detected in TeV gamma
rays, though the dominant TeV emission mechanism, i.e., leptonic or
hadronic, is still unclear. We aim to use new Chandra observations of
30 Dor C to resolve the synchrotron shell in unprecedented detail and
to estimate the magnetic field in the postshock region, a key
discriminator between TeV gamma-ray emission mechanisms."
- "The average postshock B-field determined around the X-ray
synchrotron shell of 30 Dor C suggests the leptonic scenario as the
dominant emission mechanism for the TeV gamma-rays."
