The Initial Cluster Mass Function of Super Star Clusters in Irregular and Spiral Galaxies
Jayce D. Dowell, Brent A. Buckalew, Jonathan C. Tan
The initial cluster mass function (ICMF) is a fundamental property of star formation in galaxies. To gauge its universality, we measure and compare the ICMFs in irregular and spira…
Is There Enhanced Depletion of Gas-Phase Nitrogen in Moderately Reddened Lines of Sight?
Adam G. Jensen, Brian L. Rachford, Theodore P. Snow
We report on the abundance of interstellar neutral nitrogen (NI) for 30 sightlines, using data from the Far Ultraviolet Spectroscopic Explorer (FUSE) and the Hubble Space Telescope…
Searching for a Stochastic Background of Gravitational Waves with LIGO
LIGO Scientific Collaboration
The Laser Interferometer Gravitational-wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to pr…
CHARA Array K'-band Measurements of the Angular Dimensions of Be Star Disks
D. R. Gies, W. G. Bagnuolo, E. K. Baines +22
We present the first K'-band, long-baseline interferometric observations of the northern Be stars gamma Cas, phi Per, zeta Tau, and kappa Dra. The measurements were made with multi…
Coherent searches for periodic gravitational waves from unknown isolated sources and Scorpius X-1: results from the second LIGO science run
The LIGO Scientific Collaboration
We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. The first search is targeted at isolated, pr…
