Metal Abundances and Star-Formation Rates of Emission-Line Galaxies in and around the Bootes Void
Gary Wegner, John Salzer, Joanna Taylor +1
We explore the possible dependencies of galaxy metal abundance and star-formation rate (SFR) on local environment, focusing on the volume of space in and around the Bootes Void. Ou…
Metal Abundances of KISS Galaxies. VI. New Metallicity Relations for the KISS Sample of Star-Forming Galaxies
Alec S. Hirschauer, John J. Salzer, Steven Janowiecki +1
We present updated metallicity relations for the spectral database of star-forming galaxies (SFGs) found in the KPNO International Spectroscopic Survey (KISS). New spectral observa…
The Double Galaxy Cluster Abell 2465 III. X-ray and Weak-lensing Observations
Gary A. Wegner, Keiichi Umetsu, Sandor M. Molnar +7
We report Chandra X-ray observations and optical weak-lensing measurements from Subaru/Suprime-Cam images of the double galaxy cluster Abell 2465 (z=0.245). The X-ray brightness da…
Star Formation and Supercluster Environment of 107 Nearby Galaxy Clusters
S. A. Cohen, R. C. Hickox, G. A. Wegner +2
We analyze the relationship between star formation (SF), substructure, and supercluster environment in a sample of 107 nearby galaxy clusters using data from the Sloan Digital Sky…
Star Formation and Relaxation in 379 Nearby Galaxy Clusters
Seth A. Cohen, Ryan C. Hickox, Gary A. Wegner
We investigate the relationship between star formation (SF) and level of relaxation in a sample of 379 galaxy clusters at z < 0.2. We use data from the Sloan Digital Sky Survey to…
Higgs shifts from electron-positron annihilations near neutron stars
Gary A. Wegner, Roberto Onofrio
We discuss the potential for using neutron stars to determine bounds on the Higgs-Kretschmann coupling by looking at peculiar shifts in gamma-ray spectroscopic features. In particu…
