Orbital and superorbital variability of LS I +61 303 at low radio frequencies with GMRT and LOFAR

B. Marcote, M. Ribó, J. M. Paredes +23

LS I +61 303 is a gamma-ray binary that exhibits an outburst at GHz frequencies each orbital cycle of 26.5 d and a superorbital modulation with a period of 4.6…

The 1st Fermi Lat Supernova Remnant Catalog

Fabio Acero, Markus Ackermann, Marco Ajello +156

To uniformly determine the properties of supernova remnants (SNRs) at high energies, we have developed the first systematic survey at energies from 1 to 100 GeV using data from the…

Wide-Band, Low-Frequency Pulse Profiles of 100 Radio Pulsars with LOFAR

M. Pilia, J. W. T. Hessels, B. W. Stappers +84

LOFAR offers the unique capability of observing pulsars across the 10-240 MHz frequency range with a fractional bandwidth of roughly 50%. This spectral range is well-suited for stu…

Deep view of the Large Magellanic Cloud with 6 years of Fermi-LAT observations

LAT Collaboration

The nearby Large Magellanic Cloud (LMC) provides a rare opportunity of a spatially resolved view of an external star-forming galaxy in gamma-rays. The LMC was detected at 0.1-100Ge…

2FHL: The Second Catalog of Hard Fermi-LAT Sources

LAT Collaboration

We present a catalog of sources detected above 50 GeV by the {\it Fermi}-Large Area Telescope (LAT) in 80 months of data. The newly delivered Pass 8 event-level analysis allows the…

PSR J1906+0722: An Elusive Gamma-ray Pulsar

C. J. Clark, H. J. Pletsch, J. Wu +117

We report the discovery of PSR J1906+0722, a gamma-ray pulsar detected as part of a blind survey of unidentified Fermi Large Area Telescope (LAT) sources being carried out on the v…

A LOFAR census of millisecond pulsars

V. I. Kondratiev, J. P. W. Verbiest, J. W. T. Hessels +29

We report the detection of 48 millisecond pulsars (MSPs) out of 75 observed thus far using the LOFAR in the frequency range 110-188 MHz. We have also detected three MSPs out of nin…

Limits on anisotropy in the nanohertz stochastic gravitational-wave background

S. R. Taylor, C. M. F. Mingarelli, J. R. Gair +32

The paucity of observed supermassive black hole binaries (SMBHBs) may imply that the gravitational wave background (GWB) from this population is anisotropic, rendering existing ana…

Discovery of a Spin-Down State Change in the LMC Pulsar B0540-69

F. E. Marshall, L. Guillemot, A. K. Harding +2

We report the discovery of a large, sudden, and persistent increase in the spin-down rate of B0540-69, a young pulsar in the Large Magellanic Cloud, using observations from the Swi…

Probing Atmospheric Electric Fields in Thunderstorms through Radio Emission from Cosmic-Ray-Induced Air Showers

P. Schellart, T. N. G. Trinh, S. Buitink +71

We present measurements of radio emission from cosmic ray air showers that took place during thunderstorms. The intensity and polarization patterns of these air showers are radical…

Single pulse and profile variability study of PSR J1022+1001

K. Liu, R. Karuppusamy, K. J. Lee +6

Millisecond pulsars (MSPs) are known as highly stable celestial clocks. Nevertheless, recent studies have revealed the unstable nature of their integrated pulse profiles, which may…
