A fast-turnaround pipeline for realtime data reduction plays an essential role in discovering and permitting follow-up observations to young supernovae and fast-evolving transients in modern...
View ArticleWhat can Space Resources do for Astronomy and Planetary Science?
The rapid cost growth of flagship space missions has created a crisis for astronomy and planetary science. We have hit the funding wall. For the past 3 decades scientists have not had to think much...
View ArticleNICIL: A stand alone library to self-consistently calculate non-ideal...
In this paper, we introduce Nicil: Non-Ideal magnetohydrodynamics Coefficients and Ionisation Library. Nicil is a stand-alone Fortran90 module that calculates the ionisation values and the coefficients...
View ArticleCosmic ray physics with ARGO-YBJ [Cross-Listing]
The ARGO--YBJ experiment has been in stable data taking for more than five years at the Yangbajing cosmic ray observatory (Tibet, P.R. China, 4300 m a.s.l.). The detector collected about...
View ArticleMaking maps of Cosmic Microwave Background polarization for B-mode studies:...
Analysis of cosmic microwave background (CMB) datasets typically requires some filtering of the raw time-ordered data. Filtering is frequently used to minimize the impact of low frequency noise,...
View ArticleRadiation effects on the Gaia CCDs after 30 months at L2
Since the launch of ESA's Gaia satellite in December 2013, the 106 large-format scientific CCDs onboard have been operating at L2. Due to a combination of the high-precision measurement requirements of...
View ArticleStellar photometry with Multi Conjugate Adaptive Optics
We overview the current status of photometric analyses of images collected with Multi Conjugate Adaptive Optics (MCAO) at 8-10m class telescopes that operated, or are operating, on sky. Particular...

Context. The best precision that can be achieved to estimate the location of a stellar-like object is a topic of permanent interest in the astrometric community. Aims. We analyse bounds for the best...
View ArticleExploring the Sensitivity of Next Generation Gravitational Wave Detectors...
With the development of extremely sensitive ground-based gravitational wave detectors, and the recent detection of gravitational waves by LIGO, extensive theoretical work is going into understanding...
View ArticleDual differential polarimetry. A technique to recover polarimetric...
Current mm/submm interferometers, like the Atacama Large mm/submm Array (ALMA), use receivers that register the sky signal in a linear polarization basis. In the case of observations performed in...
View ArticleSOMBI: Bayesian identification of parameter relations in unstructured...
This work describes the implementation and application of a correlation determination method based on Self Organizing Maps and Bayesian Inference (SOMBI). SOMBI aims to automatically identify relations...
View ArticleThe Peaks of Eternal Light: a Near-term Property Issue on the Moon...
The Outer Space Treaty makes it clear that the Moon is the province of all mankind, with the latter ordinarily understood to exclude state or private appropriation of any portion of its surface....
View ArticleHigh fidelity point-spread function retrieval in the presence of...
We employ electrostatic conversion drift calculations to match CCD pixel signal covariances observed in flat field exposures acquired using candidate sensor devices for the LSST Camera. We thus...
View ArticleFolding Gravitational-Wave Interferometers [Cross-Listing]
The sensitivity of kilometer-scale terrestrial gravitational wave interferometers is limited by mirror coating thermal noise. We explore the effect of folding the arm cavities of such interferometers....
View ArticleSimultaneous Observations of Giant Pulses from Pulsar PSR B0950+08 at 42 MHz...
We report the detection of giant pulse emission from PSR~B0950+08 in 12 hours of observations made simultaneously at 42~MHz and 74~MHz, using the first station of the Long Wavelength Array, LWA1. We...
View ArticleData reduction for the MATISSE instrument
We present in this paper the general formalism and data processing steps used in the MATISSE data reduction software, as it has been developed by the MATISSE consortium. The MATISSE instrument is the...
View ArticlePulsar observations with European telescopes for testing gravity and...
A background of nanohertz gravitational waves from supermassive black hole binaries could soon be detected by pulsar timing arrays, which measure the times-of-arrival of radio pulses from millisecond...
View ArticleBack-propagating the light of field stars to probe telescope mirrors aberrations
We propose a wavefront-based method to estimate the PSF over the whole field of view. This method estimate the aberrations of all the mirrors of the telescope using only field stars. In this proof of...
