A decay of the ultra-high-energy neutrino $\nu_e \to e^- W^+$ in a magnetic field and its influence on the shape of the neutrino spectrum
the ultra-high-energy neutrino the neutrino spectrum
2011/1/13
The width of the neutrino decay into the electron and $W$ boson in a strong external magnetic field is obtained from the imaginary part of the neutrino self-energy. This result corrects the formulae ...
An Initial Mass Function for Individual Stars in Galactic Disks: I. Constraining the Shape of the IMF
Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We derive a semi-empirical galactic initial mass function (IMF) from observational constraints. We assume that the star formation rate in a galaxy can be expressed as the product of the IMF, $\psi (m)...
Primary Beam Shape Calibration from Mosaicked, Interferometric Observations
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/24
Image quality in mosaicked observations from interferometric radio telescopes is strongly dependent on the accuracy with which the antenna primary beam is calibrated. The next generation of radio tele...
