Probing new physics with long-lived charged particles produced by atmospheric and astrophysical neutrinos
Shin'ichiro Ando, John F. Beacom, Stefano Profumo +1
As suggested by some extensions of the Standard Model of particle physics, dark matter may be a super-weakly interacting lightest stable particle, while the next-to-lightest partic…
An Unexpectedly Swift Rise in the Gamma-ray Burst Rate
Matthew D. Kistler, Hasan Yuksel, John F. Beacom +1
The association of long gamma-ray bursts with supernovae naturally suggests that the cosmic GRB rate should trace the star formation history. Finding otherwise would provide import…
Characterizing Supernova Progenitors via the Metallicities of their Host Galaxies, from Poor Dwarfs to Rich Spirals
Jose L. Prieto, Krzysztof Z. Stanek, John F. Beacom
We investigate how the different types of supernovae are relatively affected by the metallicity of their host galaxy. We match the SAI Supernova Catalog to the SDSS-DR4 catalog of…
Neutrino Constraints on the Dark Matter Total Annihilation Cross Section
Hasan Yuksel, Shunsaku Horiuchi, John F. Beacom +1
In the indirect detection of dark matter through its annihilation products, the signals depend on the square of the dark matter density, making precise knowledge of the distributio…
TASI Lectures on Astrophysical Aspects of Neutrinos
John F. Beacom
Neutrino astronomy is on the verge of discovering new sources, and this will lead to important advances in astrophysics, cosmology, particle physics, and nuclear physics. This pape…
TeV gamma-rays from photo-disintegration/de-excitation of nuclei in Westerlund 2
Luis A. Anchordoqui, John F. Beacom, Yousaf M. Butt +4
TeV gamma-rays can result from the photo-de-excitation of PeV cosmic ray nuclei after their parents have undergone photo-disintegration in an environment of ultraviolet photons. Th…
