An RXTE Search for the Sterile Neutrino Decay in Galaxy Clusters
Mark J. Henriksen
We have searched for the 3.55 keV line from sterile neutrino decay using 3.1 megaseconds of RXTE cluster data. A 2.5 excess of emission over a thermal model is found over the en…
RXTE Observation of the Non-thermal Emission from the Early Stage Merger in Abell 1750
Mark J. Henriksen
We make the first observation-based calculation of the energy that goes into cosmic-ray protons versus cosmic ray electrons in shock acceleration during structure formation. We fin…
Dark Galaxies in the A1367 Galaxy Cluster
Mark J. Henriksen, Scott Dusek
We have characterized a sample of extended X-ray sources in the A1367 galaxy cluster that lack optical counterparts. The sources are galaxy size and have an average total mass of $…
The Origin of Intergalactic Light in Compact Groups of Galaxies
Mark J. Henriksen
We investigate the origin of intergalactic light (IGL) in close groups of galaxies. IGL is hypothesized to be the byproduct of interaction and merger within compact groups. Compari…
A Lack of Evidence for Global Ram-pressure Induced Star Formation in the Merging Cluster Abell 3266
Mark J. Henriksen, Scott Dusek
We have selected Abell 3266 to search for ram-pressure induced star formation as a global property of a merging cluster. Abell 3266 (z = 0.0594) is a high mass cluster that feature…
Hard X-ray Emission from the NGC 5044 Group
Mark J. Henriksen
Observations made with the Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) to constrain the hard X-ray emission in the NGC 5044 group are reported here. Modelin…
