Kilometer-precise (UII) Umbriel physical properties from the multichord stellar occultation on 2020 September 21
M. Assafin, S. Santos-Filho, B. E. Morgado +39
We report the results of the stellar occultation by (UII) Umbriel on September 21st, 2020. The shadow crossed the USA and Canada, and 19 positive chords were obtained. A limb param…
The two rings of (50000) Quaoar
C. L. Pereira, B. Sicardy, B. E. Morgado +66
Quaoar is a classical Trans-Neptunian Object (TNO) with an area equivalent diameter of 1,100 km and an orbital semi-major axis of 43.3 astronomical units. Based on stellar occultat…
Observation and Spectral Measurements of the Crab Nebula with Milagro
A. A. Abdo, B. T. Allen, T. Aune +32
The Crab Nebula was detected with the Milagro experiment at a statistical significance of 17 standard deviations over the lifetime of the experiment. The experiment was sensitive t…
Observation of TeV Gamma Rays from the Crab Nebula with Milagro Using a New Background Rejection Technique
The Milagro Collaboration
The recent advances in TeV gamma-ray astronomy are largely the result of the ability to differentiate between extensive air showers generated by gamma rays and hadronic cosmic rays…
The high-energy gamma-ray fluence and energy spectrum of GRB 970417a from observations with Milagrito
R. Atkins, W. Benbow, D. Berley +38
Evidence of TeV emission from GRB970417a has been previously reported using data from the Milagrito detector. Constraints on the TeV fluence and the energy spectrum are now derived…
