The Einstein@Home Gamma-Ray Pulsar Survey II. Source Selection, Spectral Analysis and Multi-wavelength Follow-up
J. Wu, C. J. Clark, H. J. Pletsch +23
We report on the analysis of 13 gamma-ray pulsars discovered in the Einstein@Home blind search survey using Fermi Large Area Telescope (LAT) Pass 8 data. The 13 new gamma-ray pulsa…
Targeted millisecond pulsar surveys of Fermi gamma-ray sources with LOFAR
C. G. Bassa, Z. Pleunis, J. W. T. Hessels +7
We have used LOFAR to perform targeted millisecond pulsar surveys of Fermi gamma-ray sources. Operating at a center frequency of 135 MHz, the surveys use a novel semi-coherent dedi…
A Second Chromatic Timing Event of Interstellar Origin toward PSR J1713+0747
M. T. Lam, J. A. Ellis, G. Grillo +34
The frequency dependence of radio pulse arrival times provides a probe of structures in the intervening media. Demorest et al. 2013 was the first to show a short-term (~100-200 day…
The High Frequency Radio Emission of the Galactic Center Magnetar SGR J1745-29 During a Transitional Period
Joseph D. Gelfand, Scott Ransom, Chryssa Kouveliotou +6
The origin of the high-frequency radio emission detected from several magnetars is poorly understood. In this paper, we report the ~40 GHz properties of SGR J1745-29 as measured us…
Toward an Empirical Theory of Pulsar Emission XII: Exploring the Physical Conditions in Millisecond Pulsar Emission Regions
Joanna M. Rankin, Anne Archibald, Jason Hessels +6
The five-component profile of the 2.7-ms pulsar J0337+1715 appears to exhibit the best example to date of a core/double-cone emission-beam structure in a millisecond pulsar (MSP).…
LOFAR discovery of the fastest-spinning millisecond pulsar in the Galactic field
C. G. Bassa, Z. Pleunis, J. W. T. Hessels +15
We report the discovery of PSR J09520607, a 707-Hz binary millisecond pulsar which is now the fastest-spinning neutron star known in the Galactic field (i.e., outside of a globu…
FRB 121102 is coincident with a star forming region in its host galaxy
C. G. Bassa, S. P. Tendulkar, E. A. K. Adams +16
We present optical, near- and mid-infrared imaging of the host galaxy of FRB 121102 with the Gemini North telescope, the Hubble Space Telescope and the Spitzer Space Telescope. The…
A Multi-telescope Campaign on FRB 121102: Implications for the FRB Population
C. J. Law, M. W. Abruzzo, C. G. Bassa +33
We present results of the coordinated observing campaign that made the first subarcsecond localization of a Fast Radio Burst, FRB 121102. During this campaign, we made the first si…
Simultaneous X-ray, gamma-ray, and Radio Observations of the repeating Fast Radio Burst FRB 121102
P. Scholz, S. Bogdanov, J. W. T. Hessels +19
We undertook coordinated campaigns with the Green Bank, Effelsberg, and Arecibo radio telescopes during Chandra X-ray Observatory and XMM-Newton observations of the repeating fast…
The Host Galaxy and Redshift of the Repeating Fast Radio Burst FRB 121102
Shriharsh P. Tendulkar, Cees Bassa, James M. Cordes +21
The precise localization of the repeating fast radio burst (FRB 121102) has provided the first unambiguous association (chance coincidence probability ) of…
The Repeating Fast Radio Burst FRB 121102 as Seen on Milliarcsecond Angular Scales
B. Marcote, Z. Paragi, J. W. T. Hessels +26
The millisecond-duration radio flashes known as Fast Radio Bursts (FRBs) represent an enigmatic astrophysical phenomenon. Recently, the sub-arcsecond localization (~ 100mas precisi…
The direct localization of a fast radio burst and its host
S. Chatterjee, C. J. Law, R. S. Wharton +22
Fast radio bursts are astronomical radio flashes of unknown physical nature with durations of milliseconds. Their dispersive arrival times suggest an extragalactic origin and imply…
A Search for Fast Radio Bursts with the GBNCC Pulsar Survey
P. Chawla, V. M. Kaspi, A. Josephy +17
We report on a search for Fast Radio Bursts (FRBs) with the Green Bank Northern Celestial Cap (GBNCC) Pulsar Survey at 350 MHz. Pointings amounting to a total on-sky time of 61 day…
