The Geminga supernova as a possible cause of the local interstellar bubble

  title={The Geminga supernova as a possible cause of the local interstellar bubble},
  author={N. C. Gehrels and Wan Chen},
THE Solar System resides at the edge of a cavity of hot (106 K), low-density (5×10−3 cm−3), X-ray emitting gas embedded in the interstellar medium1–4. This void, sometimes called the Local Bubble, is thought to be less than 107 years old, but its origin is unknown. Here we propose that the void was caused by the supernova that produced the Geminga pulsar. The initial identification5 of Geminga as a pulsar, and the subsequent detection6–8 of pulsations in high-energy γ-rays, give an age of 3×105… 
Characteristics of nearby interstellar matter
There is a warm tenuous partially ionized cloud (T∼104 K,n(HI)∼0.1 cm−3,n(Hii∼ 0.22–0.44 cm−3) surrounding the solar system which regulates the environment of the solar system, determines the
The Milagro anticenter hot spots: cosmic rays from the Geminga supernova?
Context. The Milagro experiment has announced the discovery of an excess flux of TeV cosmic rays from the general direction of the heliotail, also close to the Galactic anticenter. Aims. We
The origin of the young stellar population in the solar neighborhood — A link to the formation of the Local Bubble?
We have analyzed the trajectories of moving stellar groups in the solar neighborhood in an attempt to estimate the number of supernova explosions in our local environment during the past 20 million
Towards a Detection of the Geminga Supernova Remnant with VERITAS
Geminga was first detected as a gamma-ray point source by the SAS-2 gamma-ray satellite observatory and the COS-B X-ray satellite observatory. Subsequent observations have identified Geminga as a
VERITAS Observations of the Geminga Supernova Remnant
Geminga was first detected as a gamma-ray point source by the SAS-2 gamma-ray satellite observatory and the COS-B X-ray satellite observatory. Subsequent observations have identified Geminga as a
Possible origin of the slow-diffusion region around Geminga
Geminga pulsar is surrounded by a multiTeV γ-ray halo radiated by the high-energy electrons and positrons accelerated by the central pulsar wind nebula (PWN). The angular profile of the γ-ray
The Sun is located inside an extremely low density and quite irregular volume of the interstellar medium, known as the Local Cavity (LC). It has been widely believed that some kind of interaction
Photometric and Spectroscopic Observations of a Diffuse Interstellar Filament in the Foreground of the Magellanic Clouds
We report the results of a photometric and spectroscopic study of stars that appear toward an infrared bright filament in the region between the LMC and SMC in the constellation Mensa. The filament
A Spectroscopic Survey of the Youngest Field Stars in the Solar Neighborhood. II. The optically faint sample
Star formation in the solar neighborhood is mainly traced by young stars in open clusters, associations and in the field, which can be identified by their X-ray emission. The determination of stellar
Open cluster ASCC21 as a probable birthplace of the neutron star Geminga
We analyze the encounters of the neutron star (pulsar) Geminga with open star clusters in the OB association Ori OB1a through the integration of epicyclic orbits into the past by taking into account


The proper motion of Geminga's optical counterpart
THE strong γ-ray source Geminga was first observed by the satellite SAS-21,2 and later seen by the COS-B satellite3,4. An association with the peculiar X-ray source 1E0630 + 178 was proposed5,
Discovery of soft X-ray pulsations from the γ-ray source Geminga
THE nature of the γ-ray source 'Geminga' (2CG195 + 04) is a problem of considerable importance in high-energy astrophysics. First discovered in 1972 by the SAS-2 satellite1, Geminga emits virtually
Optical study of the Geminga candidate field.
We have observed the field of the x-ray source IE 0630 + 178, proposed as a probable counterpart of the /-ray source 2CG 195-1-04 (Geminga). Deep CCD images of the field show two very faint optical
A theory of the interstellar medium - Three components regulated by supernova explosions in an inhomogeneous substrate
Supernova explosions in a cloudy interstellar medium produce a three-component medium in which a large fraction of the volume is filled with hot, tenuous gas. In the disk of the galaxy the evolution
The local interstellar medium
Observations and theoretical models of the local interstellar medium (LISM), defined as the region within a column density contour of 10 to the 19th H atoms/sq cm, are reviewed. The existence and
