Searching for Unmodeled Sources Using the Earth Occultation Data from the Fermi GBM
James Rodi, Gary L. Case, Michael L. Cherry +5
Employing the 12 NaI detectors in the Fermi GBM, the Earth Occultation Technique (EOT) can be used to measure the fluxes of x-ray and gamma-ray sources. Each time a source passes b…
Three years of Fermi GBM Earth Occultation Monitoring: Observations of Hard X-ray/Soft Gamma-Ray Sources
Colleen A. Wilson-Hodge, Gary L. Case, Michael L. Cherry +15
The Gamma ray Burst Monitor (GBM) on board Fermi has been providing continuous data to the astronomical community since 2008 August 12. In this paper we present the results of the…
High-energy electromagnetic offline follow-up of LIGO-Virgo gravitational-wave binary coalescence candidate events
Lindy Blackburn, Michael S. Briggs, Jordan Camp +5
We present two different search methods for electromagnetic counterparts to gravitational-wave (GW) events from ground-based detectors using archival NASA high-energy data from the…
Large Observatory for x-ray Timing (LOFT-P): A Probe-classs Mission Concept Study
Colleen A. Wilson-Hodge, Paul S. Ray, Deepto Chakrabarty +31
LOFT-P is a concept for a NASA Astrophysics Probe-Class (<$1B) X-ray timing mission, based on the LOFT concept originally proposed to ESAs M3 and M4 calls. LOFT-P requires very lar…
Discovery of spin-phase dependent QPOs in the super-critical accretion regime from the X-ray pulsar RX J0440.9+4431
Christian Malacaria, Daniela Huppenkothen, Oliver J. Roberts +5
RX J0440.9+4431 is an accreting X-ray pulsar (XRP) that remained relatively unexplored until recently, when major X-ray outburst activity enabled more in-depth studies. Here, we re…
Studying geometry of the ultraluminous X-ray pulsar Swift J0243.6+6124 using X-ray and optical polarimetry
Juri Poutanen, Sergey S. Tsygankov, Victor Doroshenko +108
Discovery of pulsations from a number of ULXs proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by several orders of magnitude. The co…
