Asymptotics of Wigner 3nj-symbols with Small and Large Angular Momenta: an Elementary Method

, 2011
Yu and Littlejohn recently studied in arXiv:1104.1499 some asymptotics of Wigner symbols with some small and large angular momenta. They found that in this regime the essential information is captured by the geometry of a tetrahedron, and gave new ...

A Direct Imaging Survey of Spitzer detected debris disks: Occurrence of giant planets in dusty systems [PDF]

, 2017
We describe a joint high contrast imaging survey for planets at Keck and VLT of the last large sample of debris disks identified by the Spitzer Space Telescope. No new substellar companions were discovered in our survey of 30 Spitzer-selected targets. We

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

Wildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Semiclassical Analysis of the Wigner $9J$-Symbol with Small and Large Angular Momenta

, 2011
We derive a new asymptotic formula for the Wigner $9j$-symbol, in the limit of one small and eight large angular momenta, using a novel gauge-invariant factorization for the asymptotic solution of a set of coupled wave equations.

A broadband radio study of the average profile and giant pulses from PSR B1821-24A [PDF]

, 2015
We present the results of wide-band (720-2400 MHz) study of PSR B1821-24A (J1824-2452A, M28A), an energetic millisecond pulsar visible in radio, X-rays and gamma-rays. In radio, the pulsar has a complex average profile which spans >85% of the spin period

Do parents expect too much or is it all about grades? The discrepancy between parents’ aspirations and child’s academic performance, and parental satisfaction with the school

Cogent Economics & Finance, 2022
Schooling is related to health and future labor market outcomes. The school parents choose for their children often depends on feedback received from other parents.

Clustering at high redshift: The connection between Lyman Alpha emitters and Lyman break galaxies

, 2013
We present a physically motivated semi-analytic model to understand the clustering of high redshift Lyman Alpha Emitters (LAEs). We show that the model parameters constrained by the observed luminosity functions, can be used to predict large scale bias ...
