The Milky Way as a Kiloparsec-Scale Axionscope
Melanie Simet, Dan Hooper, Pasquale D. Serpico
Very high energy gamma-rays are expected to be absorbed by the extragalactic background light over cosmological distances via the process of electron-positron pair production. Rece…
A 62 Day X-Ray Periodicity and an X-Ray Flare from the Ultraluminous X-Ray Source in M82
Philip Kaaret, Melanie G. Simet, Cornelia C. Lang
In 240 days of X-ray monitoring of M82, we have discovered an X-ray periodicity at days with a peak to peak amplitude corresponding to an isotropic luminosity of $2.…
The Orbital Period of the Ultraluminous X-ray Source in M82
Philip Kaaret, Melanie G. Simet, Cornelia C. Lang
The ultraluminous x-ray source (ULX) in the galaxy M82 has been identified as a possible intermediate-mass black hole. We have found that the x-ray flux from M82 is modulated with…
