Compressive sensing for spectroscopy and polarimetry
We demonstrate, through numerical simulations with real data, the feasibility of using compressive sensing techniques for the acquisition of spectro...
Concepts for future missions to search for technosignatures
New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet...
Concerning colour: The effect of environment on type Ia supernova colour in the dark energy survey
Recent analyses have found intriguing correlations between the colour (c) of type Ia supernovae (SNe Ia) and the size of their 'mass-step', the relationship...
Concerning the Existence of a ``Turbulent'' Magnetic Field in the Quiet Sun
We report on the a5F-y5Fo multiplet of Ti I and its interest for the study of ``turbulent'' magnetic fields in the quiet solar photosphere. In particular, we...
Context. CarbON CII line in post-rEionisation and ReionisaTiOn epoch (CONCERTO) instrument is a low-resolution mapping spectrometer based on lumped element...
Condensation of dust around the Wolf-Rayet star WR 125
Infrared photometry of the WC7-type Wolf-Rayet star WR 125 (MR 93) in 1981-91 shows a 10-fold rise in the 3-4 micron flux during 1990-91. This, together with...
Conditions for Reionizing the Universe with a Low Galaxy Ionizing Photon Escape Fraction
We explore scenarios for reionizing the intergalactic medium with low galaxy ionizing photon escape fractions. We combine simulation-based halo mass–dependent...
Conducting the SONG: The Robotic Nature and Efficiency of a Fully Automated Telescope
We present a description of “the Conductor,” an automated software package that handles all observations at the first Stellar Observations Network Group (SONG)...
Confidence levels of evolutionary synthesis models
The stochastic nature of the IMF in young stellar clusters implies that clusters of the same mass and age do not present the same unique values of their...
