Rotation periods of the Hyades open cluster using ASAS light curves : measuring the Hyades gyro-age and benchmarking tools for gyrochronology studies with LSST
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Rotation period distributions for older open clusters are difficult to
obtain because of the general scarcity of clusters with ages greater
than 200 Myr, as well as the challenge of measuring rotation periods
for less ...
Dark radiation from particle decays during big bang nucleosynthesis
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Cosmic microwave background (CMB) observations suggest the possibility of an extra dark
radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more
ambiguous. Dark radiation from a decaying ...
Real-time real-space density functional theory calculations of electron scattering in materials
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)
Density functional theory is utilized in real-time,
real-space simulations of LEED measurements and attosecond electron
scattering. For LEED measurements, we find that our simulation results
agree well with experimental ...
