Source Notes:
Source Position:
From
Abeysekara et al. (2017):
- R.A. (J2000): 105.12 deg (= 07h 00m 28.8s)
- Dec. (J2000): +14.32 deg (= +14d 19' 12")
- the statistical uncertainty on the position is 0.8 deg
- the systematic uncertainty on the position is 0.1 deg
Source Extent:
From
Abeysekara et al. (2017):
- "The measured extent of this source is around 2 deg"
- it was "discovered in the 1 deg extended search, with a TS of
29. The corresponding TS maximum in the 2 deg extended search is 51"
Spectral Properties:
From
Abeysekara et al. (2017):
The spectrum is given for an extension of 1 deg and of 2deg:
- 1 deg: spectral index: 2.17 +/- 0.16(stat) +/- 0.2(syst)
- 2 deg: spectral index: 2.03 +/- 0.14(stat) +/- 0.2(syst)
Source Association:
From
Linden et al. (2017):
- the authors propose that this object is a member of a new class of
TeV emitters - "extrended TeV halos"
- "Observations by HAWC and Milagro have detected bright and spatially
extended TeV gamma-ray sources surrounding the Geminga and Monogem
pulsars. We argue that these observations, along with a substantial
population of other extended TeV sources coincident with pulsar wind
nebulae, constitute a new morphological class of spatially extended
TeV halos."
From
Abeysekara et al. (2017):
- "It is likely associated with the B0656+14 pulsar, which has similar
characteristics to the Geminga pulsar: old (111 kyr), nearby (288 +33
−27 pc) and low spindown power (3.8e34 erg s−1 ) (
Brisken et al. 2003)."
