The Influence of Mergers on Scatter and Evolution in Sunyaev-Zel'dovich Effect Scaling Relations

Liang Yu, Kaylea Nelson, Daisuke Nagai

The Sunyaev-Zel'dovich effect (SZE) observable-mass (Y-M) scaling relation is a promising technique for obtaining mass estimates for large samples of galaxy clusters and holds a ke…

Asymptotic Limits of the Wigner -Symbol in Terms of the Ponzano-Regge Phases

Liang Yu

There are two types of asymptotic formulas for the symbol with one small and 11 large angular momenta. We have derived the first type of formula previously in [L. Yu, Phys. R…

Semiclassical Analysis of the Wigner -Symbol with Small and Large Angular Momenta

Liang Yu, Robert G. Littlejohn

We derive a new asymptotic formula for the Wigner -symbol, in the limit of one small and eight large angular momenta, using a novel gauge-invariant factorization for the asympt…

Uniform Approximation from Symbol Calculus on a Spherical Phase Space

Liang Yu

We use symbol correspondence and quantum normal form theory to develop a more general method for finding uniform asymptotic approximations. We then apply this method to derive a re…

Asymptotic Analysis of the Wigner -Symbol in the Bargmann Representation

Liang Yu

We derive the leading asymptotic limit of the Wigner -symbol from a stationary phase approximation of a twelve dimensional integral, obtained from an inner product between two…

Asymptotic Limits of the Wigner -Symbol with Small Quantum Numbers

Liang Yu

We present new asymptotic formulas for the Wigner -symbol with two, three, or four small quantum numbers, and provide numerical evidence of their validity. These formulas are…
