Short-term forecast of the total and spectral solar irradiance

Luis Eduardo A. Vieira, Thierry Dudok de Wit, Matthieu Kretzschmar

Among several heliophysical and geophysical quantities, the accurate evolution of the solar irradiance is fundamental to forecast the evolution of the neutral and ionized component…

Determination of the most pertinent EUV proxy for use in thermosphere modeling

T. Dudok de Wit, S. Bruinsma

Two major issues in the specification of the thermospheric density are the definition of proper solar inputs and the empirical modeling of thermosphere response to solar and to geo…

Optimized Trigger for Ultra-High-Energy Cosmic-Ray and Neutrino Observations with the Low Frequency Radio Array

K. Singh, M. Mevius, O. Scholten +100

When an ultra-high energy neutrino or cosmic ray strikes the Lunar surface a radio-frequency pulse is emitted. We plan to use the LOFAR radio telescope to detect these pulses. In t…

Determining the wavelength of Langmuir wave packets at the Earth's bow shock

V. V. Krasnoselskikh, T. Dudok de Wit, S. D. Bale

The propagation of Langmuir waves in plasmas is known to be sensitive to density fluctuations. Such fluctuations may lead to the coexistence of wave pairs that have almost opposite…

A method for filling gaps in solar irradiance and in solar proxy data

T. Dudok de Wit

Data gaps are ubiquitous in spectral irradiance data, and yet, little effort has been put into finding robust methods for filling them. We introduce a data-adaptive and nonparametr…

On the complementarity of pulsar timing and space laser interferometry for the individual detection of supermassive black hole binaries

Alessandro D. A. M. Spallicci

Gravitational waves coming from Super Massive Black Hole Binaries (SMBHBs) are targeted by both Pulsar Timing Array (PTA) and Space Laser Interferometry (SLI). The possibility of a…

Observing pulsars and fast transients with LOFAR

B. W. Stappers, J. W. T. Hessels, A. Alexov +91

Low frequency radio waves, while challenging to observe, are a rich source of information about pulsars. The LOw Frequency ARray (LOFAR) is a new radio interferometer operating in…

Evolution of the solar irradiance during the Holocene

Luis Eduardo A. Vieira, Sami K. Solanki, Natalie A. Krivova +1

Aims. We present a physically consistent reconstruction of the total solar irradiance for the Holocene. Methods. We extend the SATIRE models to estimate the evolution of the total…

Placing limits on the stochastic gravitational-wave background using European Pulsar Timing Array data

R. van Haasteren, Y. Levin, G. H. Janssen +16

Direct detection of low-frequency gravitational waves ( Hz) is the main goal of pulsar timing array (PTA) projects. One of the main targets for the PTAs is to me…

Sun-as-a-star Observation of White-Light Flares

M. Kretzschmar

Solar flares radiates energy at all wavelengths, but the spectral distribution of this energy is still poorly known. White-light continuum emission is sometimes observed and the fl…

Discovery of two millisecond pulsars in Fermi sources with the Nancay Radio Telescope

I. Cognard, L. Guillemot, T. J. Johnson +29

We report the discovery of two millisecond pulsars in a search for radio pulsations at the positions of \emph{Fermi Large Area Telescope} sources with no previously known counterpa…

The extreme physical properties of the CoRoT-7b super-Earth

A. Léger, O. Grasset, B. Fegley +23

The search for rocky exoplanets plays an important role in our quest for extra-terrestrial life. Here, we discuss the extreme physical properties possible for the first characteriz…

Disentangling stellar activity and planetary signals

I. Boisse, F. Bouchy, G. Hebrard +3

Photospheric stellar activity might be an important source of noise and confusion in the radial-velocity measurements. RV planet search surveys as well as follow-up of photometric…
