Long-term Radio Observations of the Intermittent Pulsar B1931+24
N. J. Young, B. W. Stappers, A. G. Lyne +3
We present an analysis of approximately 13-yr of observations of the intermittent pulsar B1931+24 to further elucidate its behaviour. We find that while the source exhibits a wide…
PSR J1906+0746: From relativistic spin-precession to beam modeling
Gregory Desvignes, Michael Kramer, Ismaël Cognard +4
Shortly after the discovery of PSR J1906+0746, some hints of profile variations were already interpreted as first signs of relativistic spin-precession occuring. Using observations…
SPAN512: A new mid-latitude pulsar survey with the Nancay Radio Telescope
Gregory Desvignes, Ismaël Cognard, David Champion +4
We present an ongoing survey with the Nançay Radio Telescope at L-band. The targeted area is and . This survey is charac…
Observations of transients and pulsars with LOFAR international stations and the ARTEMIS backend
Maciej Serylak, Aris Karastergiou, Chris Williams +3
The LOw Frequency ARray - LOFAR - is a new radio interferometer designed with emphasis on flexible digital hardware instead of mechanical solutions. The array elements, so-called s…
Extreme Ultraviolet Solar Irradiance during the rising phase of solar cycle 24 observed by PROBA2/LYRA
M. Kretzschmar, I. E. Dammasch, M. Dominique +3
The Large Yield Radiometer (LYRA) is a radiometer that has monitored the solar irradiance at high cadence and in four pass bands since January 2010. Both the instrument and its spa…
Sun-as-a-Star Observation of Flares in Lyman α by the PROBA2/LYRA radiometer
M. Kretzschmar, M. Dominique, I. E. Dammasch
There are very few reports of flare signatures in the solar irradiance at H i Lyman α at 121.5 nm, i.e. the strongest line of the solar spectrum. The LYRA radiometer onboard PROBA2…
M87 at metre wavelengths: the LOFAR picture
F. de Gasperin, E. Orru', M. Murgia +92
M87 is a giant elliptical galaxy located in the centre of the Virgo cluster, which harbours a supermassive black hole of mass 6.4x10^9 M_sun, whose activity is responsible for the…
A possible interpretation for the apparent differences in LFQPO types in microquasars
P. Varniere, M. Tagger, J. Rodriguez
In most microquasars, low-frequency quasi-periodic oscillations (LFQPO) have been classified into three types (A, B and C depending on the peak distribution in the PDS and the shap…
Towards a self-consistent orbital evolution for EMRIs
Alessandro Spallicci, Patxi Ritter, Sylvain Jubertie +2
We intend to develop part of the theoretical tools needed for the detection of gravitational waves coming from the capture of a compact object, 1-100 solar masses, by a Supermassiv…
Four Highly Dispersed Millisecond Pulsars Discovered in the Arecibo PALFA Galactic Plane Survey
F. Crawford, K. Stovall, A. G. Lyne +29
We present the discovery and phase-coherent timing of four highly dispersed millisecond pulsars (MSPs) from the Arecibo PALFA Galactic plane survey: PSRs J1844+0115, J1850+0124, J1…
Two Millisecond Pulsars Discovered by the PALFA Survey and a Shapiro Delay Measurement
J. S. Deneva, P. C. C. Freire, J. M. Cordes +29
We present two millisecond pulsar discoveries from the PALFA survey of the Galactic plane with the Arecibo telescope. PSR J1955+2527 is an isolated pulsar with a period of 4.87 ms,…
Intermediate behavior of Kerr tails
Anıl Zenginoğlu, Gaurav Khanna, Lior M. Burko
The numerical investigation of wave propagation in the asymptotic domain of Kerr spacetime has only recently been possible thanks to the construction of suitable hyperboloidal coor…
Self-forced gravitational waveforms for Extreme and Intermediate mass ratio inspirals
Kristen A. Lackeos, Lior M. Burko
We present the first orbit-integrated self force effects on the gravitational waveform for an I(E)MRI source. We consider the quasi-circular motion of a particle in the spacetime o…
Wide-band Simultaneous Observations of Pulsars: Disentangling Dispersion Measure and Profile Variations
T. E. Hassall, B. W. Stappers, J. W. T. Hessels +91
Dispersion in the interstellar medium is a well known phenomenon that follows a simple relationship, which has been used to predict the time delay of dispersed radio pulses since t…
First LOFAR observations at very low frequencies of cluster-scale non-thermal emission: the case of Abell 2256
R. J. van Weeren, H. J. A. Rottgering, D. A. Rafferty +79
Abell 2256 is one of the best known examples of a galaxy cluster hosting large-scale diffuse radio emission that is unrelated to individual galaxies. It contains both a giant radio…
Coronal Temperature Maps from Solar EUV images: a Blind Source Separation Approach
T. Dudok de Wit, S. Moussaoui, C. Guennou +5
Multi-wavelength solar images in the EUV are routinely used for analysing solar features such as coronal holes, filaments, and flares. However, images taken in different bands ofte…
Interaction of Close-in Planets with the Magnetosphere of their Host Stars. II. Super-Earths as Unipolar Inductors and their Orbital Evolution
Randy O. Laine, Douglas N. C. Lin
Planets with several Earth masses and a few day orbital periods have been discovered through radial velocity and transit surveys. Regardless of their formation mechanism, a key evo…
