Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
H. E. S. S. Collaboration, :, H. Abdalla +332
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies. The lowest energy threshold is obtained using monosc…
The second catalog of flaring gamma-ray sources from the Fermi All-sky Variability Analysis
S. Abdollahi, M. Ackermann, M. Ajello +124
We present the second catalog of flaring gamma-ray sources (2FAV) detected with the Fermi All-sky Variability Analysis (FAVA), a tool that blindly searches for transients over the…
A LOFAR detection of the low mass young star T Tau at 149 MHz
Colm P. Coughlan, Rachael E. Ainsworth, Jochen Eislöffel +15
Radio observations of young stellar objects (YSOs) enable the study of ionised plasma outflows from young protostars via their free-free radiation. Previous studies of the low-mass…
The Braking Index of a Radio-quiet Gamma-ray Pulsar
C. J. Clark, H. J. Pletsch, J. Wu +14
We report the discovery and timing measurements of PSR J1208-6238, a young and highly magnetized gamma-ray pulsar, with a spin period of 440 ms. The pulsar was discovered in gamma-…
The Einstein@Home Gamma-ray Pulsar Survey. I. Search Methods, Sensitivity and Discovery of New Young Gamma-ray Pulsars

We report on the results of a recent blind search survey for gamma-ray pulsars in Fermi Large Area Telescope (LAT) data being carried out on the distributed volunteer computing sys…
Detection of the magnetar SGR J1745-2900 up to 291 GHz with evidence of polarized millimetre emission
P. Torne, G. Desvignes, R. P. Eatough +6
In Torne et al. (2015), we showed detections of SGR J1745-2900 up to 225 GHz (1.33 mm); at that time the highest radio frequency detection of pulsar emission. In this work, we pres…
LBCS: the LOFAR Long-Baseline Calibrator Survey
N. Jackson, A. Tagore, A. Deller +76
(abridged). We outline LBCS (the LOFAR Long-Baseline Calibrator Survey), whose aim is to identify sources suitable for calibrating the highest-resolution observations made with the…
Entropy theorems in classical mechanics, general relativity, and the gravitational two-body problem
Marius Oltean, Luca Bonetti, Alessandro D. A. M. Spallicci +1
In classical Hamiltonian theories, entropy may be understood either as a statistical property of canonical systems, or as a mechanical property, that is, as a monotonic function of…
Spatial distribution of low-energy plasma around comet 67P/CG from Rosetta measurements
N. J. T. Edberg, A. I. Eriksson, E. Odelstad +22
We use measurements from the Rosetta plasma consortium (RPC) Langmuir probe (LAP) and mutual impedance probe (MIP) to study the spatial distribution of low-energy plasma in the nea…
Uncertainties in the Sunspot Numbers: Estimation and Implications
Thierry Dudok de Wit, Laure Lefèvre, Frédéric Clette
Sunspot number series are subject to various uncertainties, which are still poorly known. The need for their better understanding was recently highlighted by the major makeover of…
A New, Low Braking Index For the LMC Pulsar B0540-69
F. E. Marshall, L. Guillemot, A. K. Harding +2
We report the results of a 16-month monitoring campaign using the Swift satellite of PSR B0540-69, a young pulsar in the Large Magellanic Cloud. Phase connection was maintained thr…
A model for distortions of polarisation-angle curves in radio pulsars
J. Dyks, M. Serylak, S. Oslowski +4
Some radio pulsar profiles (in particular those of millisecond pulsars contain wide emission structures which cover large intervals of pulse phase. Local distortions of an average…
Massive photons from Super and Lorentz symmetry breaking
Luca Bonetti, Luís R. dos Santos Filho, José A. Helayël-Neto +1
In the context of Standard Model Extensions (SMEs), we analyse four general classes of Super Symmetry (SuSy) and Lorentz Symmetry (LoSy) breaking, leading to {observable} imprints…
Simultaneous radio and X-ray observations of PSR B0611+22
Kaustubh Rajwade, Andrew Seymour, Duncan R Lorimer +4
We report results from simultaneous radio and X-ray observations of PSR B0611+22 which is known to exhibit bursting in its single-pulse emission. The pulse phase of the bursts vary…
A deep campaign to characterize the synchronous radio/X-ray mode switching of PSR B0943+10
S. Mereghetti, L. Kuiper, A. Tiengo +14
We report on simultaneous X-ray and radio observations of the mode-switching pulsar PSR B0943+10 obtained with the XMM-Newton satellite and the LOFAR, LWA and Arecibo radio telesco…
Gauge dependence and self-force from Galilean to Einsteinian free fall, compact stars falling into black holes, Hawking radiation and the Pisa tower at the general relativity centennial
Alessandro D. A. M. Spallicci, Maurice H. P. M. van Putten
(Short abstract). In Galilean physics, the universality of free fall implies an inertial frame, which in turns implies that the mass m of the falling body is omitted. Otherwise, an…
Dispersion by pulsars, magnetars, fast radio bursts and massive electromagnetism at very low radio frequencies
Mark J. Bentum, Luca Bonetti, Alessandro D. A. M. Spallicci
Our understanding of the universe relies mostly on electromagnetism. As photons are the messengers, fundamental physics is concerned in testing their properties. Photon mass upper…

The Search for Signatures Of Transient Mass Loss in Active Stars
M. K. Crosley, R. A. Osten, J. W. Broderick +7
The habitability of an exoplanet depends on many factors. One such factor is the impact of stellar eruptive events on nearby exoplanets. Currently this is poorly constrained due to…
