The NANOGrav 11-Year Data Set: Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries
K. Aggarwal, Z. Arzoumanian, P. T. Baker +60
Observations indicate that nearly all galaxies contain supermassive black holes (SMBHs) at their centers. When galaxies merge, their component black holes form SMBH binaries (SMBHB…
The NANOGrav 11-Year Data Set: Evolution of Gravitational Wave Background Statistics
J. S. Hazboun, J. Simon, S. R. Taylor +60
An ensemble of inspiraling supermassive black hole binaries should produce a stochastic background of very low frequency gravitational waves. This stochastic background is predicte…
The NANOGrav 11-year Data Set: Pulse Profile Variability
P. R. Brook, A. Karastergiou, M. A. McLaughlin +30
Access to 50 years of data has led to the discovery of pulsar emission and rotation variability on timescales of months and years. Most of this long-term variability has been seen…
Timing of Eight Binary Millisecond Pulsars Found with Arecibo in Fermi-LAT Unidentified Sources
J. S. Deneva, P. S. Ray, F. Camilo +7
We present timing solutions for eight binary millisecond pulsars (MSPs) discovered by searching unidentified Fermi-LAT source positions with the 327 MHz receiver of the Arecibo 305…
The Third Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
M. Ackermann, M. Ajello, W. Atwood +139
The third catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT (3LAC) is presented. It is based on the third Fermi-LAT catalog (3FGL) of sources detected between 100…
Fermi-LAT detection of gamma-ray emission in the vicinity of the star forming regions W43 and Westerlund 2
M. Lemoine-Goumard, E. Ferrara, M. -H. Grondin +2
Particle acceleration in massive star forming regions can proceed via a large variety of possible emission scenarios, including high-energy gamma-ray production in the colliding wi…
The NANOGrav 11-year Data Set: Pulsar-timing Constraints On The Stochastic Gravitational-wave Background
Z. Arzoumanian, P. T. Baker, A. Brazier +57
We search for an isotropic stochastic gravitational-wave background (GWB) in the newly released -year dataset from the North American Nanohertz Observatory for Gravitational Wa…
Multiwavelength Observations of the Redback Millisecond Pulsar J1048+2339
J. S. Deneva, P. S. Ray, F. Camilo +9
We report on radio timing and multiwavelength observations of the 4.66 ms redback pulsar J1048+2339, which was discovered in an Arecibo search targeting the Fermi-LAT source 3FGLJ1…
A Search for Candidate TeV Emitters in the High-latitude Fermi Unassociated Source
P. Fortin, D. Horan, E. Ferrara
We report the results of an analysis to identify candidates for very high energy (VHE; E > 100 GeV) emission from high-latitude (|b|>10) unassociated sources in the year-1 catalog…
Hunting for treasures among the Fermi unassociated sources: a multi-wavelength approach
F. Acero, D. Donato, R. Ojha +6
The Fermi Gamma-ray Space Telescope has been detecting a wealth of sources where the multi-wavelength counterpart is either inconclusive or missing altogether. We present a combina…
