Testing the Universality of the Stellar IMF with Chandra and HST
D. A. Coulter, B. D. Lehmer, R. T. Eufrasio +8
The stellar initial mass function (IMF), which is often assumed to be universal across unresolved stellar populations, has recently been suggested to be "bottom-heavy" for massive…
Globular clusters in the far-ultraviolet: evidence for He-enriched second populations in extra-galactic globular clusters?
Mark B. Peacock, Stephen E. Zepf, Arunav Kundu +1
We investigate the integrated far-ultraviolet (FUV) emission from globular clusters. We present new FUV photometry of M~87's clusters based on archival HST WFPC2 F170W observations…
A new gamma-ray loud, eclipsing low-mass X-ray binary
Jay Strader, Kwan-Lok Li, Laura Chomiuk +5
We report the discovery of an eclipsing low-mass X-ray binary at the center of the 3FGL error ellipse of the unassociated Fermi/Large Area Telescope gamma-ray source 3FGL J0427.9-6…
An AO-assisted variability study of four globular clusters
R. Salinas, R. Contreras Ramos, J. Strader +4
The image subtraction technique applied to study variable stars in globular clusters represented a leap in the number of new detections, with the drawback that many of these new li…
